OSZS Tedlar PVF Gas Sampling Bag w/Side opening stopcock PTFE valve & septum fitting, 1L, 10-PK.
The Tedlar PVF gas sampling bag is made from polyvinyl fluoride (PVF) film produced by DuPont in the United States. The film has a thickness of 2 mil, approximately 0.05 mm.
Tedlar film exhibits excellent chemical resistance, corrosion resistance, and low adsorption of organic solvents. The water vapor transmission rate is 13 g/m².24h at 0.1 MPa, and the oxygen transmission rate is 114 cc/m².24h at 0.1 MPa (these values are measured but not guaranteed). Tedlar gas sampling bags can be used for high-precision ppm-level sampling and are suitable for collecting and preserving various corrosive gaseous and liquid samples. The heat resistance of Tedlar gas sampling bags ranges from 150°C to 170°C.
Sampling bags are a cost-effective whole-air sampling solution for high-level VOCs and permanent gases. Bags made from Tedlar® film offer good stability with VOCs and are recommended in many US EPA methods, including TCLP and methods TO-3 (VOCs), TO-12 (NMOC), TO-14A (VOCs), TO-15 (VOCs), ASTM D-5504 (reduced sulfur compounds), and various atmospheric gas methods.
They are suitable for pollution detection in products like automobile engines, auto parts, household goods, and more.
As the industry standard, Tedlar sampling bags provide a reusable storage medium with excellent retention for most substances.
Our gas sampling bag valves and seam-sealing process ensure that these bags are durable and virtually leak-proof, even under the most demanding sampling and shipping conditions.
Standard sizes for the Tedlar PVF gas sampling bags range from 0.5L to 6000L, with custom sizes and configurations available upon request.
The side-opening stopcock PTFE valve is made of polytetrafluoroethylene (PTFE). The straight-through PTFE valve features a self-sealing structure, ensuring a tight seal without any rubber components coming into contact with the gas inside the bag, thereby preventing contamination of the gas sample. The gas outlet of the lateral PTFE valve is parallel to the plane of the bag’s film, with an outer diameter of 6 mm. To open the valve, rotate the handle so it is perpendicular to the film plane; to close it, rotate the handle 90 degrees so it is parallel to the plane.
The lateral PTFE valve offers convenient and quick operation, with a compact design and a tightly sealed structure. Its gas outlet can be used for inflation, deflation, and vacuuming. This valve is suitable for filling inorganic or organic gases that do not corrode PTFE. Since the gas inside the bag does not come into contact with silicone rubber seals, it remains uncontaminated, making the PTFE lateral valve ideal for collecting and preserving low-concentration gas samples requiring high analytical accuracy.
The gas sampling bag with this valve has been patented.
