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 & 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.
