FlexFoil PLUS Sample Bags
All the benefits of Standard FlexFoil plus detection and good storage stability for low ppm to high ppb VOCs.
FlexFoil PLUS is an enhanced version of standard FlexFoil with the same benefits but with good storage stability from low ppm to high ppb level VOCs. It has good stability for low molecular weight compounds such as VOCs and CO, CO2, methane and SF6. The range has good 48 hour stability for hydrogen sulphide, carbonyl sulphide, methyl and ethyl mercaptan. It is strong and flexible and constructed from evenly sealed 4-ply (127 µm) material. Light- and moisture-proof it is excellent for light-sensitive compounds.
Applications include:
- Biogas and landfill gas sampling
- VOCs
- Pollution level monitoring
- Site sampling/mobile surveys
- Calibration gas transfer
- Calibration mixtures
- Leak/spill exposure assessment
Stocked in a variety of sizes, and available with these fittings:
- Single combined polypropylene hose/valve and septum for economy and lightweight
- Single combined stainless steel hose/valve and septum for specialist applications requiring higher temperature
Also available as Breath-gas Analysis (exhaled air fitting) Bags for storing volatile sulphur compounds (VSCs), which are important biomarkers in human breath, for up to 24 hours.
