PFA FITTING FOR 1/4" OD TUBING OR SEPTUM
  • PFA Fluoropolymer construction so sample only comes into contact with high purity, inert PFA, the ultimate in chemical resistance and non-contaminating material
  • Option of cap for tubing to allow attachment of tubing or cap with septum to allow syringe sample extraction by changing caps.
  • Replaceable fluoropolymer faced septum with large area, allows repeated punctures with common lab syringes.
  • Allows reuse of valve by only replacing septum
  • Prices include PFA fitting for 1/4" OD tubing
  • Bags with grommets available.
  • Bags with multiple fittings available.
  • Custom sized bags available.

Valve/Fitting Features

N/A

  • PFA fluoropolymer construction
  • Option of cap for tubing, or cap with septum.
  • Compression ferrule secures tubing onto fitting.
  • Replaceable fluoropolymer faced septum with large area.

Film Key Features

N/A

  • ALTEF is a proprietary fluoropolymer film developed specially for the air sampling market.
  • ALTEF meets or exceeds many of the desired characteristics of Tedlar®.
  • Unlike Tedlar®, ALTEF does not exhibit background levels of DMAC and phenol.
  • ALTEFexhibits similar stability properties as Tedlar® for a wide variety of compounds, including most VOCs.
  • Low VOC and sulfur background levels.
  • Contains no additives, fillers or pigments.
  • Minimal adsorption.
  • Superior storage for organics.
  • Abrasion Resistant.

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

  • Developed specifically for gas sampling applications
  • Chemically inert to most acids, aliphatic and aromatic organic compounds, chlorinated solvents, and alcohols
  • Maximum operating temp: 260 ºF
  • ALTEF bags are made of 0.003" thick film.
  • Tensile Strength 6100 psi

Film Advantages

N/A

  • Suitable for sampling most VOCs and many sulfur compounds
  • Low VOC background
  • Longer sample storage times than most other bag materials
  • Does not exhibit background levels of DMAC or phenol, as Tedlar® does
  • Lower permeability than Tedlar® to CO2, N2, CH4
  • Superior resistance to solvents

Film Limitations

N/A

  • More permeable to most compounds than Tedlar® (0.003" thick versus 0.002" for Tedlar® Bags)
  • Not suitable for sampling ketones and esters in high concentrations (>30 %)
  • Less resistance to UV light than Tedlar®
  • Many sulfur compounds should be analyzed within 24 hours.
  • More expensive than Tedlar®

Valve/Fitting Benefits

N/A

  • Sample only comes into contact with high purity, inert fluoropolymer PFA, the ultimate in chemical resistance and non-contaminating material.
  • Allows attachment of tubing or syringe sample extraction by changing caps
  • Superior grip compared to metal fittings.
  • Allows repeated punctures with common lab syringes.
  • Allows reuse of valve by only replacing septum.
