IN-HOUSE Sterilization

Make Sterilization Part of Your Production Process

Anprolene AN75i, EOGas 4, EOGas 310, EOGas 333

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

  • Require sterile processing of items in smaller lots
  • Are performing research
  • Have product under development, including clinical trials
  • Have a product undergoing compatibility or functionality testing
  • Manufacture custom devices and/or combination devices and drug products

Opting for In-House sterilization garners several benefits:

  • Control every aspect of your sterilization workflow and improve your ability to manage inventory
  • Reduced sterilization turnaround time
  • Scalable, expand incrementally and virtually indefinitely based on your needs
  • 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 temp (<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 temperature 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 your needs increase. Customers are sterilizing up to 10 pallets a month with this option.

EOGas 333

In-house medical device case study

Over a decade ago, one of our manufacturing customers chose to bring sterilization in-house because they wanted control over every aspect of production and inventory management. They did not want to waste the energy and effort to ship product back and forth.

The company gained control over their supply chain and cut out shipping woes by purchasing an EOGas 333. By daily in-house sterilization of device production, small and medium manufacturers can achieve the aggregate capacity of one or more commercial EO pallet chambers.

With one cabinet the company reported they could sterilize up to 10 pallets of product per month. Our systems are inherently and uniquely scalable. As their demand grew they added additional EOGas 3 cabinets to achieve necessary capacity. Today, they run 10 EOGas 333 cabinets seven days a week. They can now sterilize up to 25 pallets per week or 100 pallets per month. Note: One way many customers gain efficiency is by only sterilizing the end product (not outer product/shipping packaging).

Contract medical device case study

When the COVID-19 pandemic hit, authorities began requesting testing supplies and Keystone Solutions Group knew they could help. From first request to sending out swabs – it was just four weeks.

“Andersen Scientific was willing to jump in and understood how to get there,” said David Furchak, Launch Architect at Keystone. Andersen expedited the validation and packaging of Keystone’s swabs starting in March 2020. “The employees at Andersen have been good about figuring out the best path forward. Their collaboration and willingness to have conference calls at all hours is the key to success.”

Andersen sterilized two pallets per week from Keystone for over four months – during the peek of the pandemic. Generally, we were able to returned the swabs the day after receiving them.

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.
