Tedlar bags are the most widely used air sampling bags in the world. The bags are made from 2 mil Tedlar® film from the company DuPont® film and is strong, durable and chemically inert to a wide variety of gases. Tedlar is made of Polyvinyl Fluoride (PVF) film.
These bags are a simple, cost-effective and convenient way to sample volatile organic compounds (VOCs), inert gases, organic solvent gases and permanent gases. They are therefore suitable for sampling ambient air, indoor air and stationary source emissions.
Available Tedlar Bags
We have most bags available from stock. Below is an overview of the available bags:
- Tedlar bags with polypropylene fitting
- Tedlar sample bags with stainless steel (SS) fitting
- Tedlar bags with PTFE (Teflon) fitting
- Tedlar Bags for breath-gas sampling with a polypropylene fitting and mouthpiece
All our Tedlar gas bags feature a patented 2-in-1 fitting that combines the valve and septum into one. You can easily open and close the fitting. You can connect a hose (tubing) of 3/16″ (internal diameter of the hose) to the fitting. After sampling, you can pierce the septum with a needle to remove a sample from the bag.

Tedlar and VOCs
The Tedlar gas bags are the standard for sampling volatile organic compounds, abbreviated as VOC. The bags are used for indoor air sampling, hazardous waste locations, leaking underground storage tanks, soil gas sampling, gas mixing, calibration test standards and various other gas sampling needs.
The Tedlar bags can be used at high temperatures, depending on the fitting, the maximum temperature is 93.3 degrees Celsius (with polypropylene fitting) to 107.2 degrees Celsius (with stainless steel and PTFE fitting).

FAQ and User Instruction
On this page we have collected the frequently asked questions and you can also find a step-by-step user instruction for filling the Tedlar bags.
Custom made sample bags?
In addition to the standard Tedlar bags, we can also produce custom bags. You can think of deviating dimensions, multiple fittings, deviating fittings or, for example, leaving one side of the bag open. We have a lot of experience in producing custom made bags. Please contact us for more information.
