Catalog Number GSAP80-3030NS, 30 x 30 Inch (in) Size Multi-Layer Foil Gas Sampling Bag with Screw Cap Combo Valve® with Septum

POLYPROPYLENE SCREW CAP COMBO VALVE WITH REPLACEABLE SEPTUM
  • On/Off valve function with a replaceable 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.
  • Quick, easy opening and closing of valve to save time.
  • Cap stop limits amount cap can be opened to stop leaks from opening cap too far.
  • Visual confirmation that valve is open or closed, prevents accident sample loss.
  • No guessing whether valve is open or closed.
  • Valve Stem is 3/16" OD with tapered outer end for tubing or compression fitting.
  • Replaceable fluoropolymer faced, low bleed septum; allows reuse of valve by replacing inexpensive septum.
  • Designed and Manufactured by Jensen Inert Products specifically for gas sampling applications.
  • Prices include Screw Cap 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.

Additional Information
Catalog Number: SEP5007NSCV7010, Fluoropolymer Faced 0.070" Thick Septa, For Screw Cap Valve/10


Valve/Fitting Features
  • On/off valve function with replaceable septum in a single unit.
  • Lightweight.
  • Made of Inert polypropylene.
  • Quick turning screw cap to open and close valve. Cap stop limits amount cap can be opened.
  • Visual confirmation that valve is open or closed.
  • Replaceable fluoropolymer faced, low bleed septum.
  • Designed and manufactured by Jensen Inert Products.


Film Key Features
  • Our Multi-Layer Foil bags are the best choice for collecting and storing H2S.
  • Ideal for sampling and storing for low molecular weight compounds such as Methane, CO, CO2, Hydrogen, and inert gases which are not stable in Tedlar®, ALTEF, or FEP.
  • Water and vapor proof, these opaque, flexible bags protect light sensitive compounds.
  • They provide up to 5 day sample stability for many VOCs, with minimal adsorption.


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
  • Ideal for collecting low molecular weight compounds such as: CH4, H2S, CO, and CO2
  • Foil layers provide very low permeability and complete moisture barrier
  • Maximum operating temperature: 190 ºF
  • Opaqueness protects samples from ultraviolet light


Film Advantages
  • The only bag material that adequately holds H2S for long periods (>5 to 7 days)
  • Ideal for collecting low molecular weight compounds
  • Sample stability for up to 5 days for most compounds
  • Very low permeability to O2, CO2
  • Good VOC stability
  • Less expensive than Tedlar® and ALTEF


Film Limitations
  • Not recommended for collecting low ppm to high ppb VOC's due to background levels from bag materials
  • Recommend analyzing within 48 hours after collection for methane, hydrogen sulfide, carbon monoxide and carbon dioxide


Valve/Fitting Benefits
  • 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.
