Salient Characteristics (Redacted).pdf

This is a Salient Characteristics template for a Metal Cubic Environmental and Vacuum Chamber procurement. The document certifies that all specified characteristics are commercially available and outlines the technical specifications and performance requirements for the chamber.

The required chamber must be a cubic metal environmental and vacuum chamber with internal dimensions between 28 inches × 28 inches × 28 inches (minimum) and 30 inches × 30 inches × 30 inches (maximum). The chamber body and door must be constructed of Type 304 stainless steel with minimum wall and door thickness of 3/8 inch. It must feature a front-opening, swing-hinged door with an elastomer O-ring gasket door seal or equivalent, additional door clamp closures rated for a minimum positive pressure of seven pounds per square inch gauge, and integrated support feet with minimum height greater than 6 inches suitable for tabletop mounting. Performance requirements specify a helium leak rate of 1 × 10⁻⁸ atmosphere cubic centimeters per second or better, vacuum rating capability down to 1 × 10⁻⁶ torr with an appropriate vacuum pump, and a positive pressure rating of minimum seven pounds per square inch gauge. The chamber must include multiple ports symmetrically located on the left, right, top, rear, and bottom surfaces, including ConFlat flanges (13-1/4 inch on left and right, 6 inch on top) and various Klein flanges in 16, 25, and 40 millimeter sizes.
