FEP Gas Sampling Bag, 6" x 6", 0.6L, CHROMSPEC, with Locking Combo Valve & 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.

Locking Combo® Valve with Septum

• On/Off valve function with septum in a single unit is economical.
• Lightweight, making it easier to carry in the field and reduces shipping costs.
• Made of inert polypropylene to ensure purity of sample and non-contamination.
• Push/Pull (On/Off) valve stem for quick, easy opening and closing of valve (< 1 second).
• Faster than "twist action" valves.
• Quick locking function, in closed position. Locked position is easy to verify visually, and prevents accidental sample loss during shipment
• Virtually impossible to open or close valve too far
• Valve Stem is 3/16" diameter
• Fluoropolymer faced septum, with Ultra-low bleed silicone, prevents contamination and is located in base flange of valve with bag film below, so septum does not come into contact with sample inside bag.
• Septum allows repeated punctures with syringes without leakage
• Designed, Patented and Manufactured by Jensen Inert Products specifically for gas sampling applications.
