855 Series

Controlled Atmosphere / Anaerobic Chamber with 2 year warranty!

The 855-Series (Anaaerobic Chamber) is designed for manually controlling your atmosphere when working with oxygen sensitive materials.  It is perfect for working in situations requiring low levels of oxygen during critical isolation of the operator or your research materials.  Any inert gas may be used. 

It's main advantage is minimizing the risk of oxygen entry into the main working chamber. It trace amounts of O2 happen to enter the main chamber, the catalyst heater reduces it to water vapor.  The installed drying train system can then be activated to remove any excess water vapor.  

The 855-Series is offered as a complete system, and ready to use.  No installation is required and no additional accessories are needed.
