OSZS Tedlar PVF Gas Sampling Bag w/PTFE fitting & septum fitting, 1L capacity, 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 PTFE fitting is equipped with a sampling cap. It features a simple design without an internal O-ring for sealing.
The PTFE cap allows for needle injection, sampling, and vacuuming, and removing the cap facilitates easier sample replacement. Its straightforward design and ease of operation make it suitable for filling inorganic or organic gases that do not corrode PTFE. Since the gas sample inside the bag does not come into contact with a silicone rubber seal, it remains uncontaminated. Therefore, the PTFE fitting is ideal for collecting and storing low-concentration gas samples that require high analytical accuracy.
