Multi-Layer Foil Gas Sampling Bags

More Details
  • Good stability for low molecular weight compounds, such as methane, CO, CO2, and permanent gases.
  • Chemically inert with light and moisture protection.
  • Not recommended for low ppm VOCs due to background levels.
  • Protective 4-layer barrier minimizes gas permeability.
    - 60 gauge nylon (outer layer)
    - Polyethylene
    - 0.0003" aluminum foil
    - 0.002" polyethylene (inner layer)
  • Maximum operating temperature: 82 °C (180 °F).

    Note: Use only Point Style 5 syringes.

ALTEF Gas Sampling Bags

More Details
  • Excellent alternative to Tedlar bags for collection of most VOCs.
  • Unlike Tedlar bags, ALTEF bags do not produce background levels of dimethylacetamide (DMAC) or phenol.
  • Very low VOC and sulfur background compared to Tedlar bags.
  • Not recommended for ketones, acetates, hydrogen sulfide, or permanent gases.
  • Durable polyvinylidene fluoride (PVDF) film is resistant to abrasion and chemicals, including most acids and organic compounds.
  • Contain no additives, fillers, or pigments.

    Note: Use only Point Style 5 syringes.

Tedlar Sampling Bags

More Details
  • Find the bags you needwe offer sizes from 0.5 L to 100 L.
  • Lightweight and easy to use.
  • Available with polypropylene or stainless steel valve; choose bags with a septum fitting for syringe sampling or standard spiking.
  • Maximum operating temperature: 82 °C (180 °F) with polypropylene valves or 202 °C (397 °F) with stainless steel valves.

    Note: Use only Point Style 5 syringes.

Vacuum Pumps

(Chemker)

More Details
  • PTFE wetted parts are highly resistant to corrosive gases.
  • Diaphragm-based pump is low maintenance and virtually pollution free.
  • Quiet, low-vibration units keep disturbances to a minimum.
  • Built-in thermal protector automatically shuts off pump if it overheats and then restarts it once the unit is cool.
  • International CE and CSA certification.
  • Applications include vacuum filtration, gel electrophoresis, solid-phase extraction, solvent purification, thermal desorption (TD) tubes, sampling bags, and general use. (Not intended to evacuate air canisters.)

Vacuum Pumps

(Rocker)

More Details
  • Oil-free vacuum pumps are piston powered, so they do not pollute the air and require minimal maintenance.
  • Quiet, low-vibration units keep disturbances to a minimum.
  • Built-in thermal protector automatically shuts off pump if it overheats and then restarts it once the unit is cool.
  • Inlet filter traps particles and removes moisture, prolonging pump life.
  • International CE and CSA certification.
  • Applications include filtration for air sampling, microbiology, suspended solid test, vacuum oven, thermal desorption (TD) tubes, sampling bags, and general use. (Not intended to evacuate air canisters.)
  • Two-year pump warranty.

Vacuum Bag Sampler

More Details
  • Fast bag sampling without sample passing through pump.
  • Bag capacity up to 10 L.

Jumbo Syringe

More Details
Clear acrylic syringes, ideal for holding and dispensing large volumes of gas. An adjustable plunger on the O-ring ensures that the syringe is gas-tight over a long period of time. The central port is supplied with a luer lock fitting; the secondary port is supplied with a septum nut. This enables access to the gas sample for adding standards or removing a subsample. The plunger stem is detachable, making sample storage easy.
