Tedlar Gas Sampling Bag, 7" x7" 1L, CHROMSPEC, with Roberts Nickel Plated On/Off Valve with 1/4" Barbed Stem & Jaco PTFE-Faced Septum Fitting

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 & Separate Plastic 1/4" Jaco®Fitting with Fluoropolymer Faced Septum

You get the features of both the HR® Valve and the Jaco® Fitting on one bag

HR® Features:

• 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

Jaco® Features:

• Polypropylene molded construction is inexpensive compared to metal fittings
• Replaceable fluoropolymer faced septum with large area, allows repeated punctures with common lab syringes.
• Allows reuse of valve by only replacing septum.
• Option of cap with septum or cap with tubing, allows syringe sample extraction or attachment of tubing by changing caps.
• Compression ferrule secures tubing onto fitting, which provides a superior grip compared to metal fittings.
• Standard Jaco can be used with 1/4" tubing. Jaco for 1/2" and 3/8" tubing also available.
