General description
Multi-Layer Foil: (1) 0.002" Polyethylene (2) 0.0003" Aluminum Foil (3) Polyethylene (4) Aluminum (metalized) (5) 60 Gauge Nylon

SupelInert multi-layer foil gas sampling bags with Thermogreen LB-2 septa are ideal for sampling low molecular weight compounds such as carbon monoxide (CO), carbon dioxide (CO₂) and permanent gases. They are also suitable for sampling sulfur compounds such as hydrogen sulfide (H₂S), carbon disulfide (CS₂) and mercaptans.

Key Features and Benefits:

Multi-layer foil composed of two outer layers of aluminum film providing a great barrier to gases permeating through walls of the bag
Proven low-bleed Thermogreen LB-2 septa installed in the valve fitting
Chemically inert with moisture and light protection
Not recommended for low ppm VOCs due to background levels (we recommend the SupelInert PVDF Tedlar alternative film for VOCs)
Two valve choices available: Screw Cap Valve (SCV) and Push/Pull Lock Valve (PLV)
4 sizes: 1 L, 2 L, 5 L, and 10 L
