Vacuum parts catalog: ConFlat (CF) fittings, chambers and pumps

17 UHV components modeled from CAD, with flange sizes CF 1.33″ (DN16CF), CF 2.125″ (DN25CF), CF 2.75″ (DN40CF), CF 4.5″ (DN63CF). Each part carries its internal gas volume, wetted surface area and material, and most carry molecular transmission data, so a system you assemble from them can be simulated for pumping speed and pumpdown.
