Reid Vapor Pressure Bomb, CNGA Method-MGM 2B

Reid, ASTM D-323, Fed. Spec. Method 1201.4 and CNGA Method. Model 2B (pressure type) for testing samples that are handled at greater than atmospheric pressure. Same construction as P4120, except that a needle valve is installed in the bottom chamber and a stainless steel plug valve is interposed between the upper and lower chambers. This plug valve has no metal-to-metal contacts between moving parts, as all seals are made with synthetic rubber O-rings. This bomb consists of five parts: lower chamber, needle valve, plug valve assembly, upper chamber and gauge adapter at top.
