Abstract

An enclosure defining an anaerobic chamber for confining an anaerobic atmosphere, cuff and sleeve assemblies mounted on the enclosure in an airtight relation to the chamber so as to enable a scientist to insert his/her arms into said cuff and sleeve assemblies in an airtight manner so that his/her hands can be projected into the chamber without allowing oxygen into the chamber thereby offering the scientist the glove-free ability to handle and inspect samples in the chamber and thereby improve tactile efficiency, and an expandable and collapsible diaphragm mounted on said enclosure so as to communicate with said chamber so as to provide a continuous visual signal as to the condition of the atmosphere in the chamber, collapse of the diaphragm indicating that oxygen is leaking into the chamber.
