Tedlar Bags or Gas Sampling Bags

Tedlar bags by us are designed to collect gas/air samples. These often required for analyzing air samples for VOCs (Volatile Organic Compounds), CO (Carbon Monoxide), H2S (Hydrogen Sulfide), sulfur hexafluoride, methane, mercaptans, radon, and other such gases.

The air sampling bags fitted with two components – a PVF (Poly Vinyl Fluoride) film and Teflon/PTFE valve fitting. Apart from these, we also provide SS (Stainless Steel) and PP (Polypropylene) valve fittings.

Kynar Gas Bags

The Kynar gas sampling bags come in a variety of sizes ranges from 500ml to 10 liters. It can be customized up to 1000 liter capacity. The thickness of the PVDF film is 3mil or 0.0762mm. The dimensions of the bags vary as per their allocated capacity. It is heat-sealed adequately from all four sides to prevent leakage. Generally, the Polypropylene (PP) valve used in the Kynar bag, but customization can be possible as per client requirement. It is 2 in 1 combo valve with 7mm hose for sample inlet.

Aluminium Multi-Foil Gas Sampling Bags

The Aluminium multi-foil gas sampling bags are available in a range of capacity from 500ml to 100 liters. The combo valve is made-up of polypropylene (PP) material, with a hose connection for sample inlet and silicon septum at the top. The diameter of the hose connection is 7mm. We also supply a bag with a dual valve. The valve can be formed in other materials too such as Teflon or stainless steel (SS), which is on-demand as per client requirement.

Use of Gas Sampling Bags

The bag used for the sampling of flue gases is generally known by gas sampling bag. There are various types of sampling bags available in the market, whereas we supply mainly Tedlar bag, double valve Tedlar bags, Kynar bag and multifoil aluminium gas sampling bag. We use a patented polypropylene (PP) valve in all types of bags, where we also manufacture PTFE (Teflon) valve on demand. The design of the valve is the same in all the bags.


Our standard capacity is 0.5L, 1L, 2L, 3L, 5L and 10 liters. The customised size can also be supplied, but only in the case of bulk quantity. It comes in a rectangular shape, and maximum filling capacity of this is up to 90% only. These bags are reusable only in case of the similar type of sampling environment; once the sampling environment changed, the client has to flush it by Helium or inert gas.

Applications of Gas Sampling Bags

The primary application of these bags has seen in the effluent treatment plant, energy generation industries, and air pollution monitoring agency. It regularly used in R&D labs, industries, scientific laboratories, colleges and educational institutes, environmental agency and many more. Our gas sampling bags are well certified by many quality control agencies, where we produced the world standard product with client satisfaction.
