Designed to block light and maintain gas concentration, they operate safely within -20°C to 65°C and under 10KPa pressure, making them essential for precise, contamination-free gas collection. ## Description Single Valve BagIt's a sampling bag with only one valve installed.Double Valve BagIt's a sampling bag with two identical valves installed on it.The inlet and outlet of the single valve sampling bag pass through one valveDifferences One valve of the double valve sampling bag is inlet and the other is outlet.The advantages of the double valve bag are: several small capacity air bags can be connected in series to form a large gas sampling bag; and one in and one out is convenient for cleaning the gas sampling bag💎The product has stable chemical properties and can store general industrial gases for a long time to ensure the same concentration. It can collect hydrogen (H2), oxygen (O2), nitrogen (N2), methane (CH4), carbon monoxide (CO), carbon dioxide (CO2), industrial gases, petrochemical gases, environmental gases, greenhouse gases.💎Membrane material: PET + AL + Teflon, 💎Valve: PP valve💎The aluminum foil gas sampling bag can not measure NMHC💎The inflation pressure should not exceed 10KPA. (or the air bag is fully inflated, but it is not very tight when pressed with fingers)💎During storage and use, keep away from open fire and high temperature, and do not touch with hard objects to avoid puncturing the membrane material💎For the connection between various interfaces, instruments and equipment, the corresponding soft rubber tube should be used for transition, and the needle can be used for samplingPackage 5 Sampling Bags ## Features - 💎When filling standard gas or sampling, it is better to replace it with pre installed gas for 3 times. The sampling bag can be reused and can be cleaned with pure air or high-purity nitrogen - 💎The product has stable chemical properties and can store general industrial gases for a long time to ensure the same concentration. It can collect hydrogen (H2), oxygen (O2), nitrogen (N2), methane (CH4), carbon monoxide (CO), carbon dioxide (CO2), industrial gases, petrochemical gases, environmental gases, greenhouse gases - 💎During storage and use, keep away from open fire and high temperature to avoid sharp objects piercing. It is recommended that the inflation pressure of the sampling bag should not exceed 10KPa - 💎Suitable temperature range - 20 ℃ to + 65 ℃, The bag is opaque and can keep the gas away from light, Using our aluminum foil sampling bag, first press the cover with a little force, and then rotate the cover clockwise so that the silicone pad inside is pressed to the inside of the bag, VALVE OFF: rotate clockwise to the end, VALVE OPEN: from close to open, rotate about one circle anticlockwise - 💎You can find more sample bags of other sizes in my shop ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08G8PXNPV | | Best Sellers Rank | #515,411 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #95 in Lab Sample Bags | | Date First Available | August 21, 2020 | | Item Weight | 6.6 pounds | | Item model number | 5ml~500ml | | Manufacturer | TizZo | ## Images ![Gas Sampling Bags with Single/Double Valve, 30mL~500mL, PTFE Aluminum Foil Air Bag, Gas Collection and Storage Bag, Keep Gas Away from Light - 5Pcs (10ml, Single Valve) - Image 1](https://m.media-amazon.com/images/I/41E8w-LQ1hL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Frequently Bought Together - Gas Sampling Bags with Single/Double Valve, 30mL~500mL, PTFE Aluminum Foil Air Bag, Gas Collection and Storage Bag, Keep Gas Away from Light - 5Pcs (10ml, Single Valve) - Weigh Boats Medium (100ml, 125 Pack) Disposable Plastic Trays for Scale, Anti-Static Square Tray Weighing Dishes, Polystyrene Lab Dish for Powder Weight, Mixing Epoxy, Food Sample Container, Pour Boat - FOUR E'S SCIENTIFIC Single-Channel Pipettors Adjustable Variable Volume Micro Pipettes, 10-100 uL --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/699359845-gas-sampling-bags-with-single-double-valve-30ml-500ml-ptfe](https://www.desertcart.sn/products/699359845-gas-sampling-bags-with-single-double-valve-30ml-500ml-ptfe) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-01*
