FEP Gas Sampling Bag, 9" x9" 2L, CHROMSPEC, with Roberts Nickel Plated On/Off Valve, with 1/4" Barbed Stem

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.

Nickel Plated HR®ON/OFF Valve with 1/4" Diameter Barbed Stem

• Nickel Plated to resist damage from most aggressive chemicals.
• 1/4" Barbed Stem for attaching tubing, helps keep tubing in place.
• Leak resistant seal in closed position, prevents sample loss. However, when stem is not closed, sample air passes into the ambient air outside valve.
