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 (5-mil) 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
