|
|
|
|
|
|
NICKEL PLATED HR® ON/OFF VALVE WITH 1/4" DIAMETER BARBED STEM- Nickel Plated to resist damage from most aggressive chemicals.
- 1/4" Barbed Stem for attaching tubing, helps keep tubing in place.
- Leak resistant seal in closed position, prevents sample loss. However, when stem is not closed, sample air passes into the ambient air outside valve.
- Prices include Nickel Plated HR® ON/OFF Valve.
- Use 3/16 ID tubing on stem.
- Bags with grommets available.
- Bags with multiple fittings available.
- Custom sized bags available.

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.

- 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.
