Foil Gas Sampling Bag, 7" x7" 1L, CHROMSPEC, with Locking Combo Valve with Septum & 1 Grommet

Multi-Layer Foil Gas Sampling Bags

Our Multi-Layer Foil Gas Sampling Bags are the best choice for collecting and storing H2S. 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

Maximum operating temperature: 190 °F

Locking Combo® Valve with Septum

• On/Off valve function with septum in a single unit is economical.
• Lightweight, making it easier to carry in the field and reduces shipping costs.
• Made of inert polypropylene to ensure purity of sample and non-contamination.
• Push/Pull (On/Off) valve stem for quick, easy opening and closing of valve (< 1 second).
• Faster than "twist action" valves.
• Quick locking function, in closed position. Locked position is easy to verify visually, and prevents accidental sample loss during shipment
• Virtually impossible to open or close valve too far
• Valve Stem is 3/16" diameter
• Fluoropolymer faced septum, with Ultra-low bleed silicone, prevents contamination and is located in base flange of valve with bag film below, so septum does not come into contact with sample inside bag.
• Septum allows repeated punctures with syringes without leakage
• Designed, Patented and Manufactured by Jensen Inert Products specifically for gas sampling applications.
