Gas sampling bags are recognized as cost-effective alternatives to Summa canisters for sampling volatile organic compounds (VOCs), and light and permanent gases. We have expanded our Tedlar gas sampling bag line offering additional sizes and now available with the Screw Cap Valve. We also added more sizes to our Supel-Inert Multi-Layer foil bag product line. In addition to multiple film types, we also offer two different kinds of valves with our exclusive low-bleed Thermogreen™ LB-2 septa installed.

Gas Sampling Bags - Product Detail & Ordering Information


Tedlar Gas Sampling Bags (replaces Supel-Inert Film bags) - Ordering information back to top

Tedlar is recognized as the standard for sampling whole air, second only to the Summa canister, capable of measuring low levels of VOCs and permanent gases in the parts per million concentration range.


Gas Sampling Bags

Push/Pull Lock Valve (PLV)

Screw Cap Valve (SCV)

Key Features and Benefits:

  • Only Supelco’s Gas Tedlar bags have the industry’s lowest bleed Thermogreen LB-2 Septa assembled inside the valves, preventing sample contamination from the septum.
  • Two valve choices available – Screw Cap Valve (SCV) or Push/Pull Lock Valve (PLV)
  • Low background contamination
  • Chemically inert
  • Abrasion resistant

Supel-Inert Foil Gas Sampling Bags - Ordering Information back to top
 

Supel-Inert foil gas sampling bags with Thermogreen septa are ideal for sampling low molecular weight compounds such as carbon monoxide (CO), carbon dioxide (CO2), and permanent gases

Key Features and Benefits:

  • The Thermogreen polymer has the industry's lowest bleed, preventing sample contamination from the septum.
  • Multilayer foil composition composed of two outer layers of aluminum film providing great barrier to gases permeating through the walls of the bag
  • Only foil bag material that can hold hydrogen sulfide for long periods, from 5 to 7 days
  • Sample stability up to 5 days for most recommended compounds (direct to applications below)
  • Chemically inert with moisture and light protection
  • Not recommended for low ppm VOC’s due to background levels

Vacuum Bag Sampling Pump back to top

Our bag samplers are designed so that the sampled gas flows directly to the bags inlet without first passing through a vacuum pump, which can contaminate your sample. The pump removes the air from the box creating a vacuum; and the negative pressure inside the box causes the air to enter the inlet and flow into the bag. The desired flow rate can be achieved by adjusting the flow control valve. Products not UL listed or EX rated.
