|
|
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.

- Our Multi-Layer Foil bags are the best choice for collecting and storing H2S.
- Ideal for sampling and storing for low molecular weight compounds such as Methane, CO, CO2, Hydrogen, and inert gases which are not stable in Tedlar®, ALTEF, or FEP.
- Water and vapor proof, these opaque, flexible bags protect light sensitive compounds.
- They provide up to 5 day sample stability for many VOCs, with minimal adsorption.
|
|
|
|
- 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.

|
|
- Ideal for collecting low molecular weight compounds such as: CH4, H2S, CO, and CO2
- Foil layers provide very low permeability and complete moisture barrier
- Maximum operating temperature: 190 ºF
- Opaqueness protects samples from ultraviolet light
|
|
|
|
- The only bag material that adequately holds H2S for long periods (>5 to 7 days)
- Ideal for collecting low molecular weight compounds
- Sample stability for up to 5 days for most compounds
- Very low permeability to O2, CO2
- Good VOC stability
- Less expensive than Tedlar® and ALTEF
|
|
|
|
- Not recommended for collecting low ppm to high ppb VOC's due to background levels from bag materials
- Recommend analyzing within 48 hours after collection for methane, hydrogen sulfide, carbon monoxide and carbon dioxide

|
- 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.
