Tuttnauer 3870EA Automatic Autoclave – Full Profile

Tuttnauer 3870EA AutoclaveThe 3870 family are among Tuttnauer’s largest table top autoclaves.  (The full weight is over 200 lbs.!)  The EA version can process a huge amount of instruments at once.

Longer instruments can be run in the 15″ by 30″ chamber.  That is something to think about if you are looking to buy an autoclave and have long items.

There are a few different versions of the 3870 sterilizer series that I discuss at the bottom of this page.

First Off, Some Vital Links for this Sterilizer

I condense the specs and features while comparing the different machines within the 3870 Series.  You can listen to my annoying voice, too!

This is a large capacity machine that can fit 15 IMS sterilizing cassettes.  It has a much larger chamber compared to a sterilizer like Tuttnauer’s 2540 machine.

These autoclaves usually come with a three shelf stand and two year warranty.  I say this in most of my articles, but verify the warranty and included gear with your supplier to be %100 sure.

This automated autoclave has lots of “bells and whistles”.  Tuttnauer focused on a high amount of automation.  One button touch will lock the door, run the preset sterilization cycle, and actively dry the load.  Some of these steps help to increase the safety of your sterile instruments and gear.  Here is the full list.

List of Tuttnauer 3870 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.  (You don’t have to babysit the through the cycles like with manual models).
  • 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.

  • Automatic pressure and temperature monitoring.
  • Cycle info recovery in case of power outage or interruption of cycle.

Other 3870 Versions Besides “EA”

Tuttnauer attaches different letters to their sterilizer 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.

Though the machines may all have the 3870 number, they might look different and have various features.  I did my best to match the letters with their function in the way my “supply mind” works.  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 on my “Autoclave Reviews” Youtube Channel here.  I’ve been getting too much spam when I turn on comments here.  Take it easy.
