Ideal for sampling and storing for low molecular weight compounds such as Methane, CO, CO2, Hydrogen, and inert gases which are not stable in Tedlar®, ALTEF, or FEP. Water and vapor proof, these opaque, flexible bags protect light sensitive compounds. They provide up to 5 day sample stability for many VOC's, with minimal adsorption. Opaqueness protects samples from ultraviolet light. Foil layers provide very low permeability and complete moisture barrier\u003c\/p\u003e\u003cp class=\"richp\"\u003eMaximum operating temperature: 190 °F\u003c\/p\u003e\u003cp class=\"richp\"\u003ePTFE ON\/OFF Valve with Stopcock\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eValve is 100% inert PTFE so sample only comes into contact with PTFE\u003c\/li\u003e\n\u003cli\u003eValve stem approximately 1\/4\" OD for use with 1\/4\" or 3\/16\" ID tubing\u003c\/li\u003e\n\u003cli\u003eOptional septum with cap available\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHROMSPEC","offers":[{"title":"Default Title","offer_id":55314277531939,"sku":"TDPA0707TV","price":0.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0926\/3870\/8003\/files\/Chromspec_gas_sampling_bags_with_PTFE_on-off_valve_with_stopcock_2048x2048pxl_90a2df85-372c-4ff5-982c-7011337fff3d.jpg?v=1783550826","url":"https:\/\/chromspec.com\/products\/foil-gas-sampling-bag-7-x-7-1l-chromspec-with-ptfe-on-off-valve-with-stopcock","provider":"Chromatographic Specialties Inc.","version":"1.0","type":"link"}
