Quick Company Overview

Tuttnauer’s specialty is infection control through its line of autoclaves, (also called steam sterilizers) and other machines and products.  That’s why I am detailing their info here.

Steam sterilizers prevent harmful microbes, fungus, and disease cross contamination between patients.  Some of the settings where you can find their autoclaves (and other company’s autoclaves) are:

  • Hospitals: Surgical instruments and gear must be sterile when it comes into contact with an open wound.
  • Universities: Research facilities need sterile items to avoid contamination of their experiments, data, and biological samples.
  • Surgical clinics: Sterilizers are found in surgeon’s offices and other small locations where surgery is performed.
  • Dentists’ offices: Dental hand pieces need a specially rated type of autoclave, so keep that in mind if you are working for a dentist.
  • Research institutes: A variety of reasons exist for sterility, much like universities.
  • Laboratories: In addition to sterilizing things like petri dishes and glassware, labs need to decontaminate hazardous waste.  Sometimes this is done with Tuttnauer’s large 3870elv autoclave.
  • Veterinary offices: Our furry friends deserve sterile instruments and items, too!

Tuttnauer has a reputation for durability and reliability.  Their machines are on the high priced end, but you get the quality you pay for.  They are also widely used across the world.  That is why I’ve focused my first AutoclaveReviews.com research pages on a few Tuttnauer machines.

This is a video from Tuttnauer’s Youtube channel that was done by them as an intro to their business:

Based on my couple of months of autoclave research, they seem to be a leader in the infection control industry.

Tuttnauer EZ10 AutoclaveThe Tuttnauer EZ9 and EZ10 autoclaves are automated, table top machines.  Automatic means it is one run with a touch of the button and has preset cycles with their own time, temp, and pressure.

These are the same sterilizers except for their chamber sizes.  This article and video below is going to cover the features, specs, and differences between these sterilizers.

If you only need the user manual, try here for a pdf version you can download.

You can do me a big favor and like my videos on Youtube or leave a question in the comments.  Also think about sharing the video link with someone that is looking to buy an autoclave.  Thanks!

EZ9 and EZ10 Video on Their Features and Specs:

Overview of the Tuttnauer EZ Series

The Tuttnauer EZ10 is one of the “EZ” group of sterilizers which also includes the EZ9 and EZ11 models.  These are automated autoclaves.  Automatic means a full sterilization cycle is run at the touch of a button.  It is “set and forget”.  This automation is the main difference between Tuttnauer’s “EZ” series of autoclaves and their 2340m and 2540m cousins.

In contrast, those two autoclaves are manually operated.  Their sterilization cycles  are run by dials on the front of the machine.  When the cycle is complete, you crack the door open to dry the gear inside.

Common Features of the EZ9 and EZ10

  • The EZ series of Tuttnauer sterilizers uses an active drying system in the chamber.  This active system is more reliable for evenly drying all the packs and wrapped gear after the sterilization cycle.  It also limits possible contamination during the drying cycle since the door remains closed.
  • HEPA air filter, which is replaceable.  This aids the active drying feature in limiting contaminants that enter the chamber.
  • The inner chambers:  made of stainless steel grade 316L.  They are also electro-polished, which extends the life of the metal.  This provides more resistance to moisture, pressure, and deposits.
  • Pre-set sterilization cycles: wrapped instruments and packs, unwrapped gear, and a drying cycle.
  • Custom sterilization cycles: program and save your own custom parameters.
  • Bright blue display for easy viewing.
  • Alerts: Visual and audio in case a cycle is interrupted.
  • Pressure and temperature are constantly monitored when a cycle is running.
  • Double door locking mechanism when chamber is pressurized.
  • Ability to sterilize dental hand pieces because of its 501k clearance.
  • Water sensor: blocks the cycle when water is low.  This prevents damage to this Tuttnauer autoclave.
  • Recovery system in case of power outage.
  • Front water drain valve makes it easy to empty and clean the machine.
  • Optional printer for documentation of instrument sterilization.
  • Two year parts and labor warranty.  (Check with your dealer.  Maintenance must be done according to the manual, too.)

The Size Difference Between These Sterilizers

The EZ10 and EZ9 are similar in functions and features.  Their only difference is in the sizes and number of trays that each can hold.  There are also variations in the “K” models, which sterilize faster, but require higher electrical voltage.  You can also get an optional printer with each.

This is a graphic I made for the difference in this family of sterilizers.  The “Unwrapped Time” section means the processing times are from a “cold” autoclave start or “hot” start.  This means whether the machines’ water reservoir has been pre-heated or not.

Tuttnauer EZ9 and EZ10 Specs

I think that about covers the Tuttnauer EZ version of steam sterilizers.  I learned a ton researching these ones and hope it helped you in some way.  Leave a comment if you have more questions.

Tuttnauer 3870EA AutoclaveTuttnauer’s 3870 autoclaves are among the largest table top autoclaves on the market.  (With a total weight is over 200 lbs.!)  The EA version can process a huge amount of instruments at once.

Another benefit to the size is that longer instruments can be run in the 15″ by 30″ chamber.  Before you choose an autoclave, make sure to go through your instruments to find the longest ones that you will be processing.

There are a few different versions of the Tuttnauer 3870 that I’ll discuss towards the bottom of this post.

Some Useful Links for the 3870

Here’s my overview video for this Tuttnauer autoclave.  I cover all the different versions of this one too, such as the “m”, which is the manual one and “elv” which is “electronic, lab, vertical.”  Watch the vid so you can be really obsessed :

Needless to say, the 3870 is a large capacity machine that can fit 15 IMS sterilizing cassettes.  It has a much larger sterilization chamber compared to something like Tuttnauer’s 2540m, or Midmark’s M11 autoclaves.

I have read in places that the 3870 comes with a three shelf stand and two year warranty.  I write this all the time, but please verify the warranty and included items directly with your vendor/ supplier to be 100% sure.  Assume nothing!

Tuttnauer focused on ease of use, automation, durability, and quality in this autoclave.  One button touch (on the EA version) will lock the door, run the preset sterilization cycle, and then actively dry the load.  The can help to increase the certainty that your sterile instruments and gear will remain sterile.  Now for the full…

List of Tuttnauer 3870ea Features

  • New bright blue digital display of machine information.
  • Chamber is stainless steel, grade 316L that has been electro-polished for durability.
  • Rapid cycles for a fast sterile instrument turnover.
  • Auto shutoff after sterilization and drying cycles.
  • Double door locking mechanism while chamber is pressurized for safety.
  • Single touch controls for “set and forget” cycles.  (No need to babysit the automatic version).
  • Three pre-set sterilizing programs.
  • Replaceable HEPA filter to reduce contaminants from the air.
  • Active drying, closed door system.  This limits the chances of contamination to wet packs and pouches that are newly sterilized.
  • Ability to program and save custom cycles for your own needs.
  • Optional printer to document your completed cycles.
  • Automatic pressure and temperature monitoring.
  • Cycle info recovery in case of power outage or interruption of cycle.
  • Automatic water shutoff when low volume is detected to prevent sterilizer damage.
  • Water reservoir drain valve is at front for easy emptying and cleaning.
  • Thermostat is dual safety to prevent overheating and damaging of the autoclave.

  • Dimensions of chamber: 15″ x 27″
  • Size of Trays: Small – 1.3″ x 26.6″ x 1″; Large – 13.8″ x 26.6″ x 1″
  • Holds three standard IMS cassettes.
  • Dimensions of stand: 36″ x 24″ x 33″
  • Water capacity: 22 gal.
  • Cycle times: From cold start – 32 min.; From hot start – 23 min.
  • Weight 213 lbs.

Other 3870 Versions Besides “EA”

Tuttnauer attaches different letters to their sterilizer series within the same models.  Each letter describes a specific feature or purpose for that autoclave.  We can get an idea of the contrasts when we know what the abbreviations mean.

Though the machines may all have the 3870 number, one looks very different and others have varying features.  I did my best to match the letters with their function in the way that made sense to me.  It might not be completely accurate, to be honest.

  • 3870EA: Electronically controlled Automatic sterilizer
  • 3870M: Manual version of this autoclave.  Operated by dials on the front.  Does not have automated drying process.  Less expensive than the automatic EA version.
  • 3870EHS: Stands for Electronic, High Speed, high vacuum autoclave.  Has pre-vacuum and post vacuum cycle options.
  • 3870ELV: Electronic, Laboratory, Vertical: These versions have door at top.  They can process liquids, glass, and bio-hazard waste.
  • EAP: EA version with optional Printer.

That’s about all the information I could find for the Tuttnauer 3870EA automatic autoclave and its cousin sterilizers.  If you need some questions answered, please ask them in the comments or on my “Autoclave Reviews” Youtube Channel here.

The Tuttnauer 2540m sterilizer is a bench top, steam pressure model for processing instruments such as: dental and surgical tools, tattoo needles, nail salon gear, etc.  The “M” means it is manually run by knobs on the front.

Tuttnauer 2540M AutoclaveThis is opposed to the automatic autoclaves that are electronically controlled with preset temps and times.  The manual versions bring the prices down, but don’t sacrifice on quality, in general.

Here are answers to the top questions I see about the 2540M

Video Overview of this Steam Sterilizer

I also shot this video about the M and KM series of this autoclave. You can do me a huge favor by checking it out and liking it on Youtube, subscribing, and sharing it around.

This is a table top autoclave that sterilizes wrapped and unwrapped instruments in trays.  It’s used by dental, medical, veterinary, tattoo offices, and labs where sterile instruments are used.

The inner chamber is heated with electricity and kills germs and bacteria with steam put mechanically under pressure.  This is the same process most autoclaves use to sterilize or decontaminate gear.

The whole water reservoir has to be heated for the cycle to do its job.  The working temperature range for this steam sterilizer is from 212F to 273F, so it can process instruments sensitive to heat.  Also, the hotter cycle can work faster on more tolerant items.  (I like the versatility of that.  It’s a cool feature.)

Different Series Types of the 2540 Sterilizer

This sterilizer also comes in a Kwiklave M (called KM) series.  The dimensions, parts, and features of the “M” and “KM” are the same.  The only difference is that the KM heats up much quicker.  This is useful if your office is sterilizing a lot of instruments and needs to run through cycles quickly.

With the 2540KM model, you need a higher voltage than the M model at 220 – 235 volts.  You may need a buck/boost transformer.  I would just ask an electrician or do a bit more autoclave research on your own!

Dimensions of the Tuttnauer 2540M

  • 10″ X 19″ chamber size.  These dimensions are close to the Midmark M11 autoclave, which is 11″ X 18″.
  • Six gallon reservoir volume.
  • 21.5″ depth X 20″ width X 14.4″ height – Make sure you have the counter space!
  • Holds three full and three half standard sterilizing cassettes.
  • Four trays, each – 16.3″ depth X 6.7″ width X 0.8″ height
  • 85 pound shipping weight.  Be careful.  Safety first!

Autoclaves Similar to the 2540

There are a few sterilizers by this company that are similar in function and size.  There is a 2340M model which is most similar to the 2540M, but slightly smaller.

I also see the 3870EA version compared to these two.  The 3870 is much larger and an automatic model.  The 3870 vs 2540 prices will be about $12,000 vs $4,000, respectively.

Some Warranty Details

(From the user manual) Tuttnauer covers parts and labor on new models for one year.  This applies to materials and workmanship errors on all parts except for the door gasket and HEPA (particle) filters within the machine.  These two items are “wear items” and will need to be replaced after a certain period of time.

Also, the inside chamber is covered against defects for ten years.  This warranty does not cover misuse, neglect, altering the autoclave, or using it in an improper way.  This could be voided if not sold by an authorized dealer.  Of course, read the full manual since this page is a summary of info.

Features of the Tuttnauer 2540M Sterilizer

  • Door and chamber are “electro polished” for longer life.  (You may want to research this further.)
  • Protection from overheating with a dual thermostat.
  • Auto shutoff at the completion of sterilizing AND drying cycles.
  • Water reservoir drain valve is at the front for easy flushing and cleaning.
  • When chamber is pressurized, a dual safety lock seals the door shut for safety.
  • This sterilizer holds international certifications that are listed in the next section fully.
  • Unwrapped instruments cycle length from cold start: 30 min; from hot start: 14  min.
  • Electrical requirements: 120volt, 50/60Hz., 1400W., 12A

Standards of this Machine

Here is the list of standards for this sterilizer listed from the user manual.

  • FDA cleared
  • L61010-1 General Safety
  • L61010-2-041 Particular Safety for Autoclave
  • NISO9001:2008 – Quality System
  • SO13485:2003 – Quality Systems – Medical devices.

What is the Tuttnauer 2540M Made of?

  • Chamber: electro polished 316L stainless steel
  • Door: CF8 stainless steel
  • Trays: 304 stainless steel
  • Door handle: thermal insulated plastic

That’s it for my overview of this table top steam sterilizer.  The Midmark M11 is also close to the 2540 models in size and function, so check that one out too.

I hope this article answered your questions, whether you are looking to buy one for your office, or trying to fix yours!  Let me know in the comments if you have any more autoclave questions.  I can keep adding details to this page to make it more helpful.

As a word of safety, please don’t try to repair sterilizers and parts if it is not an easy process covered in the Tuttnauer 2540m service manual.  Simple troubleshooting has saved my ass in the past.  But, autoclaves deal with high heat, pressure, and moisture which all compound the danger in an electrical device.  Safety first always people!

Thanks for reading.  You can do me a huge favor by sharing this page or site around the web or with your colleagues.  Check out my Youtube videos here, too.  Have a good one.

Tuttnauer’s 2340M is their manually operated, table top steam sterilizer with a 9 inch diameter chamber.  The newest version of this autoclave has a white front and a blue panel on the right, like in the picture.

Tuttnauer 2340M manual autoclave

The new version of 2340M

Manual sterilizers are run by turning dials on the front of the autoclave.  There is also a 2340MK version, which seems to be discontinued because I’ve only seen old looking ones and the manual on Tuttnauer’s site only shows a 2540MK now.  The “M” stands for manual and the “K” makes it a Kwiklave, so it is faster.

Looking for the service manual?  You can find it here.  This steam sterilizer is designed to supplement a medical facility and is great for surgical clinics, dentists’ offices, tattoo offices, and any other shop that needs to sterilize a large amount of gear.

Similar Autoclaves to the 2340M

  • Midmark M9 automatic: Same chamber size sterilizer from the Midmark corporation, but an automatic (one button push) machine.
  • Tuttnauer 1730 Valueklave: This is a slightly smaller manual sterilizer and a great selling budget machine.
  • Tuttnauer EZ9 and EZ10: These autoclave machines are similar in size to the 2340, but are automatic, computer run.  That means instead of being operated by dials, it is a one button push.  The automated sterilizers are always more expensive because their computer components are always more complicated.

Dimensions and Specs

  • Weight: 85 lbs. (39 kg.)
  • Total dimensions: 21.5 in. x 20 in. x 14.4 in. (54.5 cm x 51.0 cm x 36.5 cm)
  • Chamber size: 9 in. x 18 in. (23.0 cm x 47.0 cm)
  • Chamber volume: 5 gal. (19 Liters)
  • Standard cassettes: 2 full and 2 half
  • Number of trays: 3
  • Tray dimensions: 16.3 in x 6.7 in x 0.8 in (41.5 cm x 17.0 cm x 2.0 cm)
  • Unwrapped cycle time: 27 min. (cold start), 13 min. (hot start)
  • Voltage: 120V, Frequency: 50/60 Hz
  • Power: 1400W, Current: 12A

Features of the 2340M Sterilizer

  • New bright panel
  • Pressure gauge
  • 1 year warranty on parts and labor (new machines, check your vendor)
  • Has the needed international certifications
  • Machine is protected by overheating with a dual safety thermostat
  • Water drain is at front of machine for quick draining of the reservoir.
  • Door is prevented from opening when the chamber is pressurized with a dual safety lock.
  • The autoclave shuts off automatically after sterilization cycle and drying cycle.
  • Inner part of door and chamber are electro polished for long life.

So, to summarize, Tuttnauer has been a leader in quality and durable steam sterilizers for decades.  The 2340M model is a good medium size compared to others.  It is also a great value that will deliver safe infection and disease control for your business.

Tuttnauer Elara 11 AutoclaveTuttnauer’s Elara 11 steam sterilizer is a newly designed, automated machine.  It is a pre-vacuum and post-vacuum Class B sterilizer, meaning it adheres to the European EN 13060 standards for the instruments that it’s able to run.

The Elara is also integrated with a host of electronic data features, some optional.  First, here are some quick links to help your research:

I wanted to add this detailed product overview video from Tuttnauer’s Youtube Channel:

Offices Where the Elara 11 is Most Useful

Tuttnauer describes this as mainly a “clinic” sterilizer.  It is meant to be run continuously throughout the day in surgical clinics, dental clinics, and veterinary clinics.  It is a pre-vac and post-vac workhorse, in other words.  There is no wait time between cycles (of the 11D) because of its unique steam internals.  I’ll talk about this after the “features” section.

Sizes and Specs for the Tuttnauer Elara 11

  • Standard pouch capacity: 24
  • Number of trays: 6
  • Chamber volume: 7.5 gal.
  • Chamber is made of 316L Stainless Steel
  • Electrical: 230V, 50/60Hz, 2200W, 10A

Features of this Tuttnauer Class B Sterilizer

  • Five preset programs.  Two are test cycles.  Customize up to 20 programs for special needs.
  • Separate reservoirs for clean water and waste water provides clean steam for each cycle.
  • Waste reservoir is at the back of the machine.
  • Has an energy saving sleep mode.
  • Ability to fill with clean water from the top or front.
  • Chamber and inner part of sterilizer door are mirror polished to resist corrosion.
  • Automated shutoff keeps the chamber and load from overheating.
  • Digital alert and visual alert for low clean water prevents cycle from running and damaging the autoclave.
  • Visual and audio alert when a cycle does not properly run.
  • Alert for when waste water needs to be emptied.
  • Automatic monitor of water quality.  Alerts you when water is not clean to prevent damage from minerals.
  • Multiple colored LCD display for easy viewing of cycle info.
  • 26 different languages are supported on the screen.
  • Warranty is one year parts and labor from Tuttnauer and 10 years for the inner chamber.
  • Newly designed “EZGlide” door has a double locking mechanism.  It is a simple push close without any external latching.

What Makes the Elara 11 Unique?

Internal Steam Generator:  The unique internal steam component of the Tuttnauer Elara 11D allows it to constantly run sterilization cycles.  Steam is produced by the generator constantly.  There is no waiting between autoclave cycles, which makes this a good choice for busy clinics of all types.

High Volume Vacuum Pump: Removes all air pockets pre-vac so steam can fully penetrate all the gear to be sterilized.  The same pump is used post sterilization to assist with instrument drying.  This is especially efficient for wrapped instruments.

Electronic Monitoring: The Elara 11 sterilizer can communicate through a local area network computer.  Its network port is on the rear.  You can also download the info from 200 sterilization cycles onto a USB drive.  There is also a thermal printer that is built-in for paper documentation.

(Optional) Remote PC Reporting (R.PC.R.): Allows you to track the cycle history from a connected computer.  It will track all the parameters, allow you to graph the history, and export it to a PDF file.

Tuttnauer Elara 11D vs 11I

So, everything is the same with the two models in terms of sizes and features of these autoclaves, plus whatever extras are purchased.  The only difference is in the steam generation of the machines.  The Elara 11D comes with the built in steam generator described above.  It is going to have a constant supply of steam for the cycles to be run back to back.

The Tuttnauer Elara 11I creates steam in the chamber.  It does NOT have the special steam generator and will require more heating time between loads.  Both versions are still considered “Class B”, though.  this is because they can run similar types of instruments.

That’s about it for this high tech, Class B autoclave.  It is best for busy medical and dental clinics who turn over a ton of instruments every day.  Most of the features are not needed for smaller offices.

Have a good one.

The Prestige Classic 2100 medical autoclave is a fully electric, professional grade, top loaded sterilizer by Prestige Medical U.K.  It has a similar look and size to the “pressure cooker” types of sterilizers (I cover those here).  But, the similarities end there.  This one is electric operated and is not used on the stove top.

Prestige Classic 2100 AutoclaveWhen I first found this autoclave, I had my reservations about it.  But, as I studied its features and saw its widespread popularity, I have to say that I’m impressed by this little guy!

Water is added to the chamber and an internal heating element runs the show.  The cycle is computer automated.  It is much less expensive than more robust (cube shaped) table top machines from say, Tuttnauer or Midmark  corporations.  I’ve seen the Prestige Classic 2100 for sale at around $900 for a new one.

A surprising thing I found is that the Prestige Classic is sold in 80 countries across the globe, which leads it to being one of the best selling automated autoclaves in the world.  Here is my video covering this table top sterilizer:

So, let’s get into the details of this little machine.

Dimensions of this Prestige 2100 Autoclave

  • Height: 13.2 in. (33.5 cm)
  • Machine weight: 9.9 lbs (4.5 kg)
  • Width: 13.4 in. (34 cm)
  • 120V electrical (make sure you don’t run 240V!)
  • Diameter of the Chamber: 8.3 in. (21.1 cm)
  • Height of Chamber: 9.3 in. (23.6 cm)
  • Max Weight of the Load: 6.6 lbs. (3 kg)
  • Longest Instrument that will Fit: 9 in. (22.9 cm)

Sterilizer Features and Functions

  • Compact, portable, and light weight
  • Internal instrument basket with a lid
  • Lifetime guarantee for the internal heating element
  • Listed by the Food and Drug Administration (FDA)
  • Light indicators for: power, cycle in progress and sterilization in progress.
  • Displays whether cycle was a success or failure.
  • Start cycle with one push of the button
  • Lid locks while the chamber is pressurized for safety. (It won’t blow its lid on you!)
  • Over pressurization protection X2: Pressure release valve plus a gasket offset feature.
  • It will detect if there is not enough water and turn the power off.
  • Fuse is attached to a thermostat.  If it gets too hot or there is a circuit fault, it will kick the sterilizer off.
  • Gasket will last 750 cycles.
  • 11 minute sterilizer cycle is very fast (trust me).

In summary, the Prestige Classic looks pretty solid for its price and compact size.  Through my research, this one seems to stand in a category of its own.  It is a useful autoclave for dentists, podiatrists, tattoo artists, piercing artists, nail salons and similar uses.

I am not sure if I would recommend it for surgical uses.  I would prefer a better controlled vacuum environment.  Given its popularity across the world, price, and portability, I would definitely recommend it for the listed offices, though.
