N/A

Catalog No. CAP-14-PS, Extra Cap with Septum for PFA fitting, Each

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.

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.

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

• 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

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

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^®

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.
