Catalog Number GSF001P-2430LJC, 24 x 30 Inch (in) Size FEP Gas Sampling Bag with Locking Combo® Valve with Septum

POLYPROPYLENE LOCKING COMBO® VALVE WITH SEPTUM
  • On/Off valve function with septum in a single unit is economical.
  • Lightweight, making it easier to carry in the field and reduces shipping costs.
  • Made of inert polypropylene to ensure purity of sample and non-contamination.
  • Push/Pull (On/Off) valve stem for quick, easy opening and closing of valve (< 1 second).
  • Faster than "twist action" valves.
  • Quick locking function, in closed position. Locked position is easy to verify visually, and prevents accidental sample loss during shipment
  • Virtually impossible to open or close valve too far
  • Valve Stem is 3/16" diameter
  • Fluoropolymer faced septum, with Ultra-low bleed silicone, prevents contamination and is 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
  • Designed, Patented and Manufactured by Jensen Inert Products specifically for gas sampling applications.
  • Prices include Locking Combo® Valve with septum.
  • 3/16 OD stem for use with most 1/4" OD plastic and fluoropolymer tubing.
  • Bags with grommets available.
  • Bags with multiple fittings available.
  • Custom sized bags available.

  • Lightweight.
  • Made of Inert polypropylene.
  • Push/Pull (On/Off) valve stem.
  • Quick Locking function, in closed position, with visual confirmation. No tools required.
  • Fluoropolymer faced septum, with Ultra-low bleed silicone.
  • Designed, patented and manufactured by Jensen Inert Products.


Film Key Features
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.


Suggestion
  • 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.


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


Film Advantages
  • 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


Film Limitations
  • 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®


Valve/Fitting Benefits
  • 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.
