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 from Polyvinyl Fluoride (PVF), the fluorine contained in the polyvinyl fluoride film results in a stronger chemical bond than in normal polymers. This makes Tedlar more resistant to sunlight, solvents, acids, bases, moisture and oxidation.
We have the Tedlar gas bags available in different sizes and with various fittings. We usually have the bags available from stock, ordered before 4 p.m. on working days and shipped the same day.

You can easily order (on account) via our webshop. If you prefer to order via a purchase order, you can do so by email via info@medi-sense.nl. Do you need large quantities? Please contact us for an additional discount.
Not sure if these bags are the right choice for you? Please send us an email with the gases you want to sample so that we can advise you on the most suitable gas bags. Perhaps the multi foil bags, Kynar or Teflon bags are a better choice.
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. We recommend using Inert PTFE tubing because it prevents adsorption of the sample on the tubing’s inner surface.

After sampling, you can pierce the septum with a needle to remove a sample from the bag.

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.
Read more about the stability of different gasses in the bags (and other sample bags) on this page.
The Tedlar bags are available with different fittings such as polypropylene, PTFE and stainless steel. The polypropylene fitting is the most commonly used and meets the requirements in many cases. Which fitting is most suitable for you depends on the temperature at which you want to use the bags. The polypropylene fitting is suitable for temperatures up to 93.3 degrees Celsius. The PTFE and stainless steel fitting are suitable for temperatures up to 107.2 degrees Celsius. Is there a chance that the fitting will be exposed to corrosive materials? We also recommend using a PTFE or stainless steel fitting as they offer high corrosion resistance.
All our Tedlar gas bags feature a patented 2-in-1 fitting that combines the valve and septum in one. You can easily open and close the fitting. To the stem of the fitting you can connect a hose (tubing) of 3/16″ (internal diameter of the hose). Inert PTFE hoses are recommended because they prevent adsorption of the sample on the inside of the hose.
After sampling, you can pierce the septum with a needle to remove a sample from the bag.
