Tedlar Gas Sampling Bag,12" x 12", 5L,CHROMSPEC, with Locking Combo Valve with Septum

Tedlar® Gas Sampling Bags

• Tedlar® film has very low gas permeation levels for most compounds, and high tensile strength.
• Bags resist puncture in the field.
• 2 mil Tedlar® film is an economical alternative to FEP bags.
• Tedlar® is much less permeable than FEP, PFA and TFM and is unaffected by the chemical components of gasses generally sampled like, carbon monoxide, sulfur dioxide, hydrogen sulfide, radon and mercaptans.
• Tedlar® withstands temperatures up to 400 degrees.
• Tedlar® is recommended in many EPA testing methods.

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.
