NICKEL PLATED HR® ON/OFF VALVE WITH 1/4" DIAMETER BARBED STEM AND SEPARATE PLASTIC 1/4" JACO® FITTING WITH FLUOROPOLYMER FACED SEPTUM

You get the features of both the HR® Valve and the Jaco® Fitting on one bag

HR® Features:

  • Nickel Plated to resist damage from most aggressive chemicals
  • 1/4" Barbed Stem for attaching tubing, helps keep tubing in place
  • Leak resistant seal in closed position, prevents sample loss. However, when stem is not closed, sample air passes into the ambient air outside valve

Additional Information

N/A

  • Catalog No. CAP-14-JT, Cap, Polypropylene, Jaco® Set Up for 1/4" Tubing
  • Catalog No. SEP5007-JSF-10, Septa, 10/90, 10 mm for Jaco Fitting/10 EA.

Valve/Fitting Features

N/A

  • Compression ferrule secures tubing onto fitting.
  • Polypropylene molded construction.
  • Option of cap for tubing, or cap with septum.
  • Replaceable fluoropolymer faced septum with large area.
  • Nickel Plated
  • Barbed stem for attaching tubing.
  • Leak resistant seal in closed position.

Film Key Features

N/A

Tedlar® film has very low gas permeation levels for most compounds, and high tensile strength. Bags resist puncture in the field. 2 mil Tedlar® film is an economical alternative to FEP bags. Tedlar® is much less permeable than FEP and is unaffected by the chemical components of gases generally sampled, like carbon monoxide, sulfur dioxide, hydrogen sulfide, radon and mercaptans. Continuous use temperature from -98 to 400 ºF (temperature limit depends on fittings used). Required for many EPA testing methods.

Suggestion

N/A

  • 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

N/A

  • Low gas permeation levels - Most gases
  • High tensile strength
  • Withstands temperatures up to 400 ºF
  • Unaffected by the chemical components of gases commonly sampled, like carbon monoxide, sulfur dioxide, hydrogen sulfide, radon, and mercaptons
  • Tensile Strength 8000 psi

Film Advantages

N/A

  • Less permeable than FEP, PFA, and TFM
  • Bags resist puncture in the field
  • Less expensive than FEP, PFA, and TFM film
  • Recommended in many EPA testing methods

Film Limitations

N/A

  • Exhibits background levels of DMAC and phenol
  • High permeation rate for CO2
  • Relatively high permeation rate for O2
  • *NOTE: We offer bags specially conditioned to remove DMAC and phenol from Tedlar®

Valve/Fitting Benefits

N/A

  • Superior grip compared to metal fittings.
  • Inexpensive compared to metal fittings.
  • Allows attachment of tubing or syringe sample extraction by changing caps.
  • Allows repeated punctures with common lab syringes.
  • Allows reuse of valve by only replacing septum.
  • Resists damage from most aggressive chemicals.
  • Helps hold tubing in place.
  • Prevents sample loss in closed position. However, when stem is not closed, sample air passes into ambient air outside valve.
