The bottom section of the chamber shall be fabricated from stainless steel wire cloth or mesh and consist of two containers, one symmetrically mounted within the other and permanently secured at the joint between the top and bottom sections.
The lid assembly shall be provided with a charge of catalyst (see notes), capable of producing and maintaining an anaerobic atmosphere within the jar at room temperature indefinitely, unless contaminated by hydrogen sulfide, when used in conjunction with the other components of the overall anaerobic apparatus.
Workmanship. The lid shall be free from defects which detract from its appearance or impair its serviceability.
Unit. Each (EA). One lid as specified constitutes one unit.
