OSZS Multi-layer foil gas sampling bag w/Daul Copper alloy chrome plated 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 metal valve is constructed from chrome-plated copper alloy, with an outer diameter of 7 mm. The valve’s sampling cap, also made of chrome-plated copper alloy, features a silicone pad that facilitates needle sampling, sample extraction, and vacuum operations.
For gas inflow or outflow, the sampling cap can be removed to allow the attachment of a hose, such as a latex or silicone tube, which can be secured with a hose clamp. The design is straightforward and user-friendly, making it ideal for collecting and storing inorganic and organic gas samples that are non-corrosive to copper or silicone rubber.
