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\"\u003eNickel Plated HR® ON\/OFF Valve with 1\/4\" Diameter Barbed Stem \u0026amp; Separate Plastic 1\/4\" Jaco®Fitting with Fluoropolymer Faced Septum\u003c\/p\u003e\u003cp class=\"richp\"\u003eYou get the features of both the HR® Valve and the Jaco® Fitting on one bag\u003c\/p\u003e\u003cp class=\"richp\" sugg=\"true\"\u003e\u003cb\u003eHR® Features:\u003c\/b\u003e\u003c\/p\u003e\u003cp class=\"richp\"\u003eNickel Plated to resist damage from most aggressive chemicals\u003c\/p\u003e\u003cp class=\"richp\"\u003e1\/4\" Barbed Stem for attaching tubing, helps keep tubing in place\u003c\/p\u003e\u003cp class=\"richp\"\u003eLeak resistant seal in closed position, prevents sample loss.
