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.
• Low VOC and sulfur background levels.
• Similar stability properties as Tedlar^® for a wide variety of compounds, including most VOCs.
• Developed as an alternative to Tedlar^® film for most gas sampling applications.
• Contains no additives, fillers or pigments.
• Choice of ten fitting options.
• Minimal adsorption.
• Superior storage for organics.
• Inherently pure.

ALTEF is not recommended for ketones or esters in high concentrations (>30%)
ALTEF is not suitable for storing H₂S.
Our Multi-Layer Foil bags are the best choice for collecting and storing H₂S.

N/A

• Stainless steel construction.
• Option of cap for tubing or septum.
• Replaceable fluoropolymer faced septum with large area.

• Minimal adsorption.
• Superior storage for organics.
• Abrasion Resistant.

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.

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

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

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^®

N/A

• Durable and able to withstand use in austere sampling conditions.
• Allows attachment of tubing or syringe sample extraction by switching caps.
• Allows repeated punctures with common lab syringes. Allows reuse of valve by only replacing septum.
