N/A Catalog Number: SEP5007NSCV7010, Fluoropolymer Faced 0.070" Thick Septa, For Screw Cap Valve/10

N/A

• On/off valve function with replaceable septum in a single unit.
• Lightweight.
• Made of Inert polypropylene.
• Quick turning screw cap to open and close valve. Cap stop limits amount cap can be opened.
• Visual confirmation that valve is open or closed.
• Replaceable fluoropolymer faced, low bleed septum.
• Designed and manufactured by Jensen Inert Products.

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

• Economical: Cost savings in manufacturing is passed on to customers. Septum can be changed.
• Reduces shipping costs. Easier to carry in the field.
• Ensures purity of sample and non-contamination.
• Quick, easy opening and closing of valve: saves time. Cap stop leaks from opening cap too far.
• Prevents accidental sample loss. No guessing whether valve is open or closed.
• Allows reuse of valve by replacing inexpensive septum.
• Designed specifically for gas sampling applications.

• Economical: Cost savings in manufacturing is passed on to customers.
• Reduces shipping costs. Easier to carry multiple bags into the field.
• Ensures purity of sample and non contamination.
• Quick, easy opening and closing of valve (< 1 second).
• Faster than "twist action" valves.
• Locked position is easy to verify visually, and prevents accidental sample loss during shipment. Virtually impossible to open or close valve to far.
• Septum does not come into contact with sample inside bag. Septum allows repeated punctures with syringes without leakage. Ultra low bleed silicone prevents contamination.
• Designed specifically for gas sampling applications.
