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 (300ml, Double Valves)

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

• 💎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
