Protecting Patients
For more than six decades, Andersen Sterilizers has focused on just one thing —
the design and manufacturing of effective and affordable low-temperature
sterilization solutions for healthcare, veterinary, research and manufacturing markets.
We help you protect your patients and preserve your instruments.
Is HLD Enough?
Hospital-acquired infections not only put your patients at risk, but also put practices at risk. They have been reported as recently as fall 2024
Responding to a 2019 outbreak, in 2020 FDA disseminated an alert that sterilization, particularly terminal (e.g., gas) sterilization, provides a greater margin of safety than high-level disinfection.
Andersen’s FDA-cleared EOGas 4PLUS provides terminal sterilization for a wide range of medical devices, including those with complex lumens that can degrade using other modalities, such as steam and H2O2. FDA-cleared, EOGas 4PLUS is the only system proven to sterilize the longest lumens.
Commonly Sterilized Items
Andersen systems deliver terminal sterilization (10⁻⁶ SAL) without compromising device integrity — no dulling, clouding, or degradation. Commonly sterilized devices include:
- Flexible endoscopes (including the longest lumens)
- Hand-pieces and cords
- Mix-material instruments or trays
- Implants, sharps, plastics, rubber, non-wovens/cellulose, fiber optics, electronics and batteries

WHY CHOOSE ANDERSEN
Discover the Advantages of Choosing Andersen for Your Research Needs
From FDA-clearances to award-winning EO technology, our sterilizers deliver reliability, safety, and efficiency for your research and laboratory needs.
FDA Clearances
Our sterilizers are FDA-cleared for medical settings. We have 18 clearances covering everything from the sterilization of the longest and narrowest colonoscope lumens.
Size Matters
Our space-saving tabletop designs enable even the smallest practices to have access to sterilization solutions that ensure their patients are protected.
Eliminate Superbugs
Hospital-acquired infections not only put your patients at risk, but also put practices at risk. With incidents on the rise, sterility is no longer a luxury but a simple necessity.
Abatement Option
We are proud to offer dry catalyst resin abators. The resin converts ethylene oxide to biodegradable organic compounds. This contrasts catalytic abators that burn off EO and can be expensive to install.
Time
When you think about staff time management, don’t just consider sterilization time, also consider capacity. Instead of running all day, staff can run one sterilization cycle overnight.
Operator Safety
Our exclusive technology works behind the scenes to keep your staff safe. The microdose of EO and smart cabinet design are just two of these safeguards.
Why Ethylene Oxide?
There are many benefits to ethylene oxide sterilization, some of which may be crucial to your hospital or clinic, especially when reprocessing complex multi-channel endoscopes and delicate medical devices. Andersen’s FDA-cleared sterilizers offer several advantages, including low per-cycle cost, low-temperature operation and EO-Flexible Chamber Technology, which allows our systems to use a microdose of EO — just 17.6 grams per cycle. Our systems are able to achieve terminal sterilization (10-6 SAL) with 90% less EO than our competitors — this is ethylene oxide sterilization reimagined.
