• Designed, patented and manufactured by Jensen Inert Products.

FEP is one of the most chemically inert materials for making gas sampling bags. It works well in extreme temperatures ranging from -400 to 400 ºF; allowing it to be used in most stack sampling conditions. 5 mil FEP film is completely resistant to the most severe corrosives. Much more permeable than Multi-Layer or Tedlar®. FEP bags can be specified for applications involving corrosive gases.

• Before use, thoroughly flush bags with ultra-pure nitrogen or zero air
• During sampling, Fluoropolymer tubing and Fluoropolymer faced septums must be used in order to prevent sample loss.
• Bags should not be filled to more than 80% of their maximum volume.
• Charcoal (Black) Tedlar^® bags should be used when sampling light sensitive compounds
• Do not store compounds in bags long term due to the possibility that chemicals may adsorb onto the bag surface.
• Bags should not be used to collect reactive or unstable compounds.
• When shipping bags, do not air-ship unless the bags are stored in a pressurized area.

• One of the most chemically inert materials available for making gas sampling bags
• Maximum operating temperature: 400 ºF
• Virtually transparent

• Works well in extreme temperatures ranging from -400 to 400 ºF; allowing it to be used in all stack sampling conditions
• Heavier gauge (0.005) film is resistant to most severe corrosives as well as tolerates applications involving rough handling or difficult service conditions
• Less expensive than PFA

• Poor long term storage stability for most VOC's and sulfur compounds
• Much more permeable than Tedlar^®, ALTEF, and Multi-Layer Foil bags
• More expensive than Tedlar^®, ALTEF, Multi-Layer Foil, and TFM bags
• Lower tensile strength than Tedlar^®

• Economical: Cost savings in manufacturing is passed on to customers.
• Reduces shipping costs. Easier to carry multiple bags into the field.
• Ensures purity of sample and non-contamination.
• Quick, easy opening and closing of valve (< 1 second).
• Faster than "twist-action" valves.
• Locked position is easy to verify visually, and prevents accidental sample loss during shipment. Virtually impossible to open or close valve to far.
• Located in base flange of valve with bag film below, so septum does not come into contact with sample inside bag. Septum allows repeated punctures with syringes without leakage. Ultra-low bleed silicone prevents contamination.
• Designed specifically for gas sampling applications.
