Case Study
In-house manufacturing case study
Challenges:
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.
Solutions:
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.
Results:
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).
Case Study
Contract manufacturing case study
Challenges:
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.
Solutions:
“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.”
Results:
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?
Why Now?
Other methods miss what EO gas reaches. EO sterilizes 100% of surfaces, even in hard-to-reach lumens and complex devices. With just a microdose (17.6g), EO Gas 4+ uses 10x less gas than competitors — proving safer doesn’t mean weaker.
