FEP Gas Sampling Bag, 12" x12", 5L, CHROMSPEC, with Screw Cap Combo Valve with Septum

FEP Gas Sampling Bags

FEP is one of the most chemically inert materials for making gas sampling bags. It works well in extreme temperatures ranging from -400 to 400°F; allowing it to be used in most stack sampling conditions. Much more permeable than Multi-Layer or Tedlar®. Heavier gauge (0.005") film is resistant to most severe corrosives as well as tolerates applications involving rough handling or difficult service conditions. Virtually transparent.
