OSZS Multi-layer foil gas sampling bag w/PTFE straight-through valve & septum fitting, 1L, 10-pk.
The OSZS multi-layer foil gas sampling bag (Multifoil gas sampling bag) provides an economical and reliable solution for air sampling. Constructed with a composite material comprising nylon membrane (PA), aluminum foil (AL), and polyethylene film (PE), these layers are bonded using a two-component adhesive. This design is specifically engineered to safeguard light-sensitive gas samples, making it ideal for standard gas sampling and filling applications where chemical stability is crucial. These applications include oil-cracking gas, natural gas, coal bed gas, flue gas, ambient air, process reaction gases, and inorganic gases such as nitrogen, hydrogen, oxygen, and argon.
The material's chemically inert properties ensure that it does not interfere with or contaminate the collected air samples. It offers robust protection against light and moisture, while also providing exceptional physical strength and chemical stability. The bag is opaque, features low adsorption and permeability, and is completely airtight.
The innovative seam construction enhances durability, and the heat-sealed seams ensure a leak-proof performance.
These sampling bags are an effective and economical choice for air sampling of high-level volatile organic compounds (VOCs) and permanent gases. They are extensively used in petrochemical industries, environmental protection efforts, and scientific research institutions. However, due to the potential for background contamination, they are not recommended for sampling low PPM VOCs.
Standard sizes for the Aluminum-Foil (Multi-Layer) Gas Sampling Bags range from 0.5L to 6000L, with custom sizes and configurations available upon request.
The OSZS PTFE inline valve is constructed from polytetrafluoroethylene (PTFE), featuring a self-sealing design that ensures a secure seal without any rubber components coming into contact with the gas inside the bag, thereby preventing contamination of the gas sample.
The gas inlet tube of the PTFE inline valve is oriented perpendicular to the membrane of the gas sampling bag, with an outer diameter of 6 mm. To open the valve, rotate the handle so that it is perpendicular to the membrane plane; rotate it 90 degrees to make the handle parallel to the membrane plane to close the valve.
The PTFE inline valve is designed for ease and speed of operation while providing a reliable seal. The upper end of the gas inlet tube can accommodate a sampling cap fitted with a silicone pad for needle sampling. The tube is versatile, suitable for filling, emptying, and vacuuming operations. It is ideal for handling inorganic or organic gases that do not corrode PTFE.
Since the gas sample inside the bag does not come into contact with the silicone rubber pad, there is no risk of contamination, making the PTFE inline valve interface highly suitable for the collection and preservation of low-concentration gas samples requiring high analytical accuracy.
