Multi-Foil bags provide light and moisture protection for low molecular weight compounds such as hydrogen that are unstable when collected in standard bags such as Tedlar sample bags. This multi-layer foil bag has a polypropylene 2-in-1 fitting that combines the valve and septum into one.
We usually have the 0,5 – 10 liter multi foil bags with polypropylene fitting available from stock.
The Kynar® PVDF sample bags are made of 3mil Kynar® PVDF (PolyVinyliDene Fluoride) film. The bags are delivered with an eyelet and the patent-pending single 2-in-1 fittings that combine the valve and septum into one.
