Tedlar Gas Sampling Bag, 12" x 12", 5L, CHROMSPEC, with Roberts Nickel Plated On/Off Valve with 1/4" Barbed Stem

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.

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.
