Sterilize More with Terminal Sterilization

Andersen’s FDA-cleared sterilization systems use Ethylene Oxide-Flexible Chamber Technology® (EO-FCT) to provide terminal sterilization for a wide range of veterinary devices, helping hospitals and clinics control costs without compromising safety. EO-FCT works differently from traditional rigid-chamber ethylene oxide systems. By removing excess air from the chamber before sterilization, EO-FCT needs only a microdose of EO (just 17.6 grams) to achieve full sterilization. Rigid-chamber systems, by comparison, can require up to 90% more ethylene oxide to reach the same result.

High-temperature and chemical sterilization methods can damage heat-sensitive electronics, thermolabile polymers, bonded materials, and other delicate components. Excessive heat, moisture, and oxidation can cause corrosion, material degradation, and shortened device lifespan — problems Andersen sterilizers are designed to solve.

Material Compatibility

Andersen’s AN75 and EOGas 4 systems are FDA-cleared to sterilize complex devices — including scopes with lumens longer than 1,100 mm — to a 10⁻⁶ Sterility Assurance Level (SAL), effectively eliminating pathogens. Trusted by veterinary practices worldwide, both systems combine low per-cycle cost with a space-saving tabletop design and broad device compatibility.

Andersen’s sterilizers are compatible with:

• Heat-sensitive devices
• Metal devices
• Rubber-based devices
• Vessel sealing tools (e.g., LigaSure)
• Optical scopes and electronics
• Cautery units
• Syringes and tubing
• Sutures and needles
• Scalpels and blades
• Wraps

Efficient & Effective

With a minimum cycle time of 3.5 hours, the EOGas 4 lets busy clinics run multiple sterilization loads per day — ideal for practices handling same-day surgeries. Faster turnaround keeps procedures on schedule and reduces reliance on costly backup instruments, saving clinics time, space, and money.

Whether you need a compact solution like the Anprolene AN75 or a higher-capacity option like the EOGas 4, Andersen offers sterilization systems built to fit your clinic’s workflow and budget. Backed by decades of experience and expert technical support, Andersen Sterilizers helps veterinary teams build sterilization processes that protect both patients and instruments.

A sterilizer for every need.
