Andersen Sterilizers, Inc.

Andersen Sterilizers, Inc. is a global manufacturer of FDA-cleared ethylene oxide (EO) sterilization systems for healthcare, veterinary, research, and manufacturing applications. The company specializes in proprietary Ethylene Oxide-Flexible Chamber Technology (EO-FCT), which achieves terminal sterilization (10-6 SAL) using 90% less ethylene oxide than competitive rigid-chamber systems—typically just 17.6 grams per cycle. Founded by Dr. H.W. Andersen, the company offers a tiered product portfolio including the newly released EOGas 4PLUS (designed for difficult-to-sterilize endoscopes including duodenoscopes and colonoscopes), the EOGas 4 (suitable for surgical centers and large-animal veterinary practices), the EOGas 3 (compact, efficient model with built-in microprocessor control), and the AN75 Series (room-temperature tabletop sterilizers ideal for veterinary and mobile clinic settings). All systems are designed for low per-cycle cost, low-temperature operation, and preservation of delicate instruments. The company operates with FDA clearances and maintains manufacturing and service capabilities in Haw River, North Carolina, and a secondary office in Morrisville, North Carolina, serving hospitals, surgical centers, veterinary practices, and contract sterilization/reprocessing facilities globally.
