Abstract:
An enclosure defining an anaerobic chamber for confining an anaerobic atmosphere, side-by-side access openings in said enclosure, cuff and sleeve assemblies operatively connected to said enclosure at said openings so that the assemblies are in an airtight relation to said enclosure so as to enable a user of the chamber to insert his/her arms into said cuff and sleeve assemblies in an airtight engagement with the enclosure so that the users hands can be projected into the chamber without allowing oxygen into the chamber thereby offering the user the glove-free ability to handle and inspect samples in the chamber, means forming an opening in said enclosure communicating with said chamber, an expandable diaphragm mounted on said enclosure so as to close said opening thereby providing a continuous visual signal as to the condition of the atmosphere in the chamber, the outward bulging of the diaphragm indicating that oxygen is not leaking into the chamber, and when the diaphragm collapses it is a signal that oxygen is leaking into the chamber.
