• 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.

• 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.

• 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.

• 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.

• 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

• 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

• 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^®

• 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.
