The gas sampling bags made up of Polyvinyl Fluoride (PVF) film, which is a patented product of the Du Pont. The commercial name of PVF is Tedlar; hence it is known as Tedlar bag. Generally, it used for the gas analysis application in the hot stack and industrial chimneys where the temperature of flue gas is very high. Due to its high resistance to the heat, this is the ideal sampling bag in these conditions.

The maximum operating temperature of the Tedlar bag is 170 degree C. In contrast, the safe temperature for the continuous operation is 110 OC. The thickness of the PVF film is 2 mil (25.4 microns), whereas the bag dimensions vary as per the capacity. Generally, the standard capacity of the Tedlar bag is 500ml, 1 liter, 2 liters, 3 liters, 5 liters, and 10 liters. The customization is also possible as per the client’s requirement. It is advisable to store at room temperature. It has an excellent impermeability to many gases, which decreases the losses and increase the holding time during the storage period. It can store the air sample up to 6 to 7 days, which makes it portable and handy during the field study. It is reusable by using proper pre-treatment with inert gases or vacuumed it totally by using a vacuum pump.

It classified into two major types based on the number of valves. The one is a single valve Tedlar bag, and the other is a dual vale Tedlar bag. Usually, the single valve bag is used for the batch sapling; while the double valve bags used for the continuous operation. The valve made up of polypropylene (PP), in which the silicon septum is non-removable. The Teflon and stainless steel (SS) valves also provided based on the requirement.


  • Take a fresh gas sampling bag and air filling pump.
  • Note the sample number, time, and date on the sticker.
  • The rubber tube of the pump should be attached to the hose present on the valve.
  • Make sure that the fitted tube in the hose is completely tight.
  • Open the valve by turning it in the anti-clockwise direction.
  • Fill the bag with the help of a pump.
  • It is advisable to fill the sample only up to 90% capacity of the bag to prevent leakages and excessive pressure on the film.
  • Once the bag filled with sampling gas, then closed it by turning the valve in the clockwise directions.
  • Then detached the rubber tube from the hose, which makes it available for gas analysis.
  • Take out the samples through the small hole present at the top of a valve
  • The sampling performs by airtight syringe through the septum in Gas chromatography (GC).

We manufacture and supply this product at a low price. The bags customized in all the sizes as per the required volume and applications, where customization is available only for the orders more than 100 quantity. It is far better than the summa canisters and other sampling devices. As per customization demands, we also equipped a Tedlar bag with a vacuum box.
