Gas Sampling Bags

ALTEF Gas Sampling Bags 
Low VOC and sulfur background levels. Similar stability properties as Tedlar® for a wide variety of compounds, including most VOCs. Developed as an alternative to Tedlar® film for most gas sampling applications. Suitable for sampling and analysis of most VOCs within 2 days, and many sulfur compounds for up to 24 hours. Abrasion Resistant. Chemically Inert to most acids, aliphatic and aromatic organic compounds, chlorinated solvents, and alcohols. Contains no additives, fillers or pigments. Minimal adsorption.  Superior storage for organics. Inherently pure. Gas Sampling Bags are available with various valves, fittings, configurations and materials.

Tedlar® Gas Sampling Bags 
Low Permeability, Chemically Inert, Minimal Sample Loss, No Plasticizers, Reusable/Cleanable, Leak Tested, Non-Contaminating, Mechanically Strong. Gas Sampling Bags are available with various valves, fittings, configurations and materials.

Multi-Layer Foil Gas Sampling Bags 
Multi-Layer Foil Bags are ideal for containing low molecular weight gases. The 2 layers of aluminum film provide a great barrier to gases permeating through the walls of the bag.
Chemical composition of Multi-Layer Foil bags listed from outer to inner layers : 60 gauge Nylon, Polyethylene, .0003" Aluminum Foil, .002" Polyethylene 

FEP Gas Sampling Bags 
Chemically Inert, Minimal Sample Loss, No Plasticizers, Reusable/Cleanable, Leak Tested, Non-Contaminating, Mechanically Strong. Gas Sampling Bags are available with various valves, fittings, configurations and materials.
