1L Aluminum Foil Gas Sampling Bag with Dual PP Valves, High-Opaque Leakproof Gas Collection Bag for Lab Research, Routine Analysis & Industrial Air Testing (5PCS)

• 【Low-Permeability Material】Made ofPremium multi-layer aluminum foil composite film. Features excellent chemical stability and a non-adsorbent inner surface to ensure gas samples remain pure during collection, transport, and short-term storage.
• 【Dual Valve】Designed with two PP valves for simultaneous inflation and sampling. Ideal for continuous gas flow.
• 【Reinforced Sealing Design】Features heat-sealed edges designed to support structural integrity and consistent sealing during standard use. The flexible composite material is suitable for routine gas collection, offering general durability for various laboratory and field sampling tasks.
• 【Versatile Gas Sampling Tool】Widely used for environmental monitoring, air quality testing, industrial gas sampling, occupational safety monitoring, petrochemical analysis, and scientific laboratory research. Suitable for chemically stable and low-reactivity gases.
• 【Multiple Sizes & Pack Options】Choose from 8 capacities (0.5L, 1L, 2L, 3L, 4L, 5L, 10L, 15L) with either Single or Dual PP valves to fit your sampling volume. Available in 1pc, 5pcs, or 10pcs packs to suit both small-scale lab research and large-scale industrial projects.
• 【Notice】Maximum inflation pressure: 3KPa. Operating temperature: -20°C to +65°C. To open the valve, rotate 1/2 turn anticlockwise. Lightweight and foldable for easy transport. Keep away from open flames and sharp objects. (Not for non-methane hydrocarbon detection).
