We are supplying wide range of gas sampling Tedlar/ Kynar bags. Tedlar gas sampling bags are made of 2mil PVF (Tedlar) film. Tedlar is tough, durable, and considered chemically inert to a wide range of compounds. Tedlar bags can be used for indoor air sampling, hazardous waste sites, leaking underground storage tanks, stack sampling, soil gas sampling, gas blending, calibration test standards, and most other gas sampling needs. Our Tedlar bags feature an eyelet and our patent-pending single 2-in-1 fittings that combine the valve and septum into one. Polypropylene, stainless steel, and teflon fittings are available.
