Picarro Partners with SOLSTEO to Enable Safer, More Responsible Ethylene Oxide Sterilization

Technology leading EtO gas analyzers, sterilization equipment and expert consulting services will now be available throughout Europe, the Middle East, and South-East Asia 

Santa Clara, CA – November 17, 2020 – Picarro Inc., a leading provider of trace gas analyzers for a variety of air and emissions monitoring applications, today announced a partnership with SOLSTEO, the European market leader in industrial sterilization. Through this partnership, the companies will provide customers throughout EMEA and South-East Asia with a one-stop-shop for market-leading Ethylene Oxide (EtO) gas concentration analyzers and high-performance EtO sterilization equipment, plus expert consultancy, training, sales and support. 

EtO is an important chemical used for the sterilization of medical equipment and a common ingredient in the industrial production of other compounds. Known to have mutagenic properties even at low concentrations, there are major concerns about the effects of long-term exposure on humans, and regulatory bodies worldwide are re-evaluating exposure limits. Picarro and SOLSTEO customers will be able to better control and monitor EtO, achieve compliance to regulations, improve worker safety, demonstrate environmental and corporate responsibility, and optimize costs for process maintenance.

“With their proven expertise in medical sterilization using EtO, SOLSTEO is an ideal partner for Picarro,” said Joel Avrunin, Vice President of Scientific Instrumentation for Picarro. “We’re pleased to be working with them to bring our advanced EtO gas analyzers to sterilization facilities around the world.”

“In addition to being able to detect EtO at parts-per-trillion levels, Picarro’s are the most user-friendly gas analyzers,” said Jean-Baptiste Bonnet, Technical Director at SOLSTEO. “Combining this highly sensitive technology with our state-of-the-art sterilization equipment will enable our customers to easily measure and monitor EtO and prevent overexposure.”

Picarro EtO Analyzers
Using innovative, next-generation Cavity Ring-Down Spectroscopy (CRDS) laser technology, Picarro has developed a gas analyzer family capable of measuring parts-per-trillion (ppt) levels of EtO (C2H4O)  in real time (less than 2 seconds) – and without the need for chromatographic separation or pre-concentration. These analyzers enable services providers, regulators, and industrial users of EtO such as medical sterilization companies, to accurately and effortlessly measure and monitor EtO. With this technology, customers can adapt to changing regulations, protect the health of workers and the environment by minimizing exposure, and reduce maintenance costs by identifying and fixing or replacing only faulty components rather than entire systems.
