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. Septum can be changed.
- Reduces shipping costs. Easier to carry in the field.
- Ensures purity of sample and non-contamination.
- Quick, easy opening and closing of valve: saves time. Cap stop leaks from opening cap too far.
- Prevents accidental sample loss. No guessing whether valve is open or closed.
- Allows reuse of valve by replacing inexpensive septum.
- Designed specifically for gas sampling applications.
- 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.
- 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.
