Consider purchasing an Andersen sterilizer for in-house sterilization if you:

  • Require sterile processing of items in smaller lots
  • You have items or devices that are sensitive to heat or moisture
  • Have a wide variety of items to sterilize (EO is the most versatile method available)
  • Need to sterilize frequently

Opting for In-House sterilization garners several benefits:

  • Speed up the pace of research with on-site sterilization
  • Mitigate contamination concerns by keeping samples in the lab
  • Our sterilizers have a small footprint
  • Feature easy, inexpensive installation
    • No tanks, external compressors or fixed water lines
  • Are extremely affordable – essential equipment in every wet lab
  • Are self contained units – The liner bag acts as the chamber and the cabinet acts at the EO containment area or vent hood
  • Are easy to use and come with a gas sterilization expert, providing free training and decades experience working with environmental and health industry regulators
  • Control every aspect of your sterilization workflow and improve your ability to manage inventory
  • Reduced sterilization turnaround time
  • Reduced transportation costs and environmental impact
  • Allowed in municipalities where other gas sterilizers are not, due to Andersen’s ultra-low emissions

Three in-house sterilizer line choices

AN75 Series is FDA Cleared



A favorite of universities and research labs! This tabletop sterilizer is easy to install and operate. Validated to achieve a 10-6 SAL at room temperature (<68ºF) with a 12- or 24-hour cycle.

EOGas 4 is FDA Cleared



Temperature-controlled tabletop unit with four cycles as fast as 3.5 hours (including aeration). Low temp for R&D and heated for those scaling-up to a validated process.

EOGas 333



Use this large volume system as part of a validated process. Expand capacity easily as needs increase. Customers are sterilizing up to 10 pallets a month with this option.

    • Two weeks
    • One week
    • 24 to 48 hours
  • Can customize cycles to meet your specific requirements


  • Validation
    • Sterilization process
    • Packaging (including sealer)
    • Shelf-life & transportation studies
    • Residual testing
  • Contract sterilization
  • Lab services


Achieves FDA-required 10-6 sterility assurance level (SAL) for terminal sterilization of medical devices. In fact, we have 15 recent FDA clearances.


Our exclusive EO-Flexible Chamber Technology and the resulting ability to use a microdose of EO has garnered two national awards.


With Andersen you can choose in-house sterilization, contract or both. Any way you slice it, Andersen makes it so easy.

Oversee every aspect of your sterilization workflow and improve your ability to manage inventory.

Anprolene AN74i

Our newest Anprolene series, the FDA-cleared AN75, recently launched and offers upgrades ideal for a laboratory setting.

In-house university research case study

Researchers at a leading university needed to sterilize pollen on a microbial level for a study on bee feeding habits. The sterilization method had to be gentle and effective. The team had been bogged down with a time-intensive process in-house and it didn’t want to risk contamination or delays by sending pollen out to be sterilized.

The university research team purchased an Anprolene AN74i. Anprolene is our most affordable option and the room temperature cycles are gentle enough…well…to sterilize pollen!

The sterilizer has made their process more “efficient and effective” so the doctors and their team can concentrate on what they do best. Note: Many facilities will install an inexpensive Anprolene unit in each lab to eliminate the possibility of cross-contamination.

Why ethylene oxide (EO/EtO) sterilization?

Ethylene oxide is the gold standard in sterilization. It offers hospital-level sterility assurance (10⁻⁶) along with
unparalleled gentleness and material compatibility.
