Anaerobic Chamber NAC-100 is anaerobic systems with controlled atmosphere that are also designed with high capacity incubator and large work area. These chambers attain the desired atmospheric conditions by eliminating oxygen down to 0-5ppm by reacting 5% or less hydrogen gas with a palladium catalyst. Equipped with two sets of gloves and an airlock transfer chamber permits the operator to enter the glove box without compromising the atmosphere inside thereby increasing the tactile efficiency. The unit requires minimal daily maintenance and is easy to use for working with oxygen sensitive materials, product containment needs, and/or general isolation control.
