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\"\u003eScrew Cap Combo Valve® with Septum\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOn\/Off valve function with a replaceable septum in a single unit is economical.\u003c\/li\u003e\n\u003cli\u003eLightweight, making it easier to carry in the field and reduces shipping costs.\u003c\/li\u003e\n\u003cli\u003eMade of inert polypropylene to ensure purity of sample and non-contamination.\u003c\/li\u003e\n\u003cli\u003eQuick, easy opening and closing of valve to save time.\u003c\/li\u003e\n\u003cli\u003eCap stop limits amount cap can be opened to stop leaks from opening cap too far.\u003c\/li\u003e\n\u003cli\u003eVisual confirmation that valve is open or closed, prevents accident sample loss.\u003c\/li\u003e\n\u003cli\u003eNo guessing whether valve is open or closed.\u003c\/li\u003e\n\u003cli\u003eValve Stem is 3\/16\" OD with tapered outer end for tubing or compression fitting.\u003c\/li\u003e\n\u003cli\u003eReplaceable fluoropolymer faced, low bleed septum; allows reuse of valve by replacing inexpensive septum.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHROMSPEC","offers":[{"title":"Default Title","offer_id":55281906352419,"sku":"TDPA2424S","price":0.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0926\/3870\/8003\/files\/Chromspec_multi-layer_foil_gas_sampling_bag_screw_cap_valve_2048x2048pxl_440bfdeb-989f-4887-82f2-e79f89cce732.png?v=1782486363","url":"https:\/\/chromspec.com\/products\/foil-gas-sampling-bag-24-x-24-40-l-chromspec-with-screw-cap-combo-valve-with-septum","provider":"Chromatographic Specialties Inc.","version":"1.0","type":"link"}
