Tedlar® PVF Gas Sampling Bag with stopcock side-opening valve with silicone septum TDL11_0.3L (air sample bag)

Tedlar air sample bags   Referenced in Many EPA Methods

      Tedlar

• Made of clean top-grade Tedlar film for sample integrity and valid data

• Resists gas permeation both into and out of the bag

• Classic bag for VOCs referenced in many EPA methods

• Good stability for some sulfur compounds, including hydrogen sulfide

Description:

Tedlar®PVF Gas Sampling Bags are constructed of 2-mil thick Tedlar® with solid seam to keep gases contained. Tedlar® film is polyvinyl fluoride (PVF) film produced by DUPONT USA.

In the late 1970s SKC USA used Tedlar film to make gas sampling bags for the first time, Tedlar® PVF is strong, durable, and considered chemically inert to a wide range of compounds. Tedlar gas sampling bag can be used in high precision PPM level analysis sampling, can sample and save all kinds of corrosive gas and liquid samples, the heat-resistance temperature of Tedlar is 150℃～170℃. For over 30 years, the SKC USA constantly promoted Tedlar to make users all around the world generally accepted Tedlar gas sampling bags and approved by USA EPA. At present Tedlar gas sampling bags are also recommended in domestic.

In recent years, country environmental regulations are increasingly strict, detection business of testing institutions detecting organic volatile residue for cars, household goods and other products of civilian use is also increasing. Our company can customize large size Tedlar Sampling Bags, which can reach 3000MM, volume 6000L, trilateral edge sealing side and one side sealed with straight rod clamp(3m)(as shown below), used to solid VOCs residual detection. Such as automobile engine, automotive parts, household items pollution detection.

Tedlar gas sampling bags are accredited by regulatory agencies in different countries and widely used indoor air sampling, waste processing yard gas sampling, soil sampling and other environmental protection application. Our Tedlar sampling bags come with renovated, patented valves. The materials of the valves are Polycarbonate(PC) or Polytetrafluoroethylene(PTFE) or Polypropylene(PP); Depending on inlet orientation, there are two types of valves: one type is that the inlet in vertical to the film, the other one type is the inlet horizontal to the film, both valves have the same functionalities: has on/off function; has a sample cap with septum inside for syringe sampling purpose, both valves are easy to use. One advantage of horizontal valve(side opening) is touse less storage space.

• Low gas permeation levels
• High tensile strength
• Continuous temperature range from –98°F to 225°F
• Unaffected by the chemical components of gases commonly sampled, like carbon monoxide, sulfur dioxide, hydrogen sulfide, radon and mercaptans

Standard Tedlar Gas Sampling Bag Sizes: 50ml～0.5L, 1L, 2L, 3L, 4L, 5L, 8L, 10L, 15L, 20L, 30L, 40L～6000L or customized size.

Select from a variety of sizes to suit your needs.
