Silcocan Air Sampling Canister, 3 L, No Valve



Features & Benefits
  • Siltek-treated canister with optional Siltek-treated valve offers unsurpassed inertness, even for sulfur-containing or brominated compounds.
  • High-quality, metal-to-metal seal, 2/3-turn valve with stainless-steel diaphragms prevents sample adsorption for more accurate results.
  • Canisters and valves made of 304 and 316 stainless steel to withstand the rigors of field work.
  • Both 2-port and 3-port valves are available; 3-port valve includes -30" Hg/60 psi vacuum/pressure gauge (other gauges available).
  • Featuring the proven long life, leak-free performance, and effortless operation of RAVE+ valves.

Looking for a cost-effective alternative to canisters for highly contaminated samples, such as soil gas? Our disposable air sampling bottles are housed in a foam-filled protective box to prevent breakage during sampling, transportation, and analysis.


For ultimate inertness, SilcoCan air sampling canisters feature our unique Siltek treatment technology. Even highly active components at low parts-per-billion concentrations can be readily sampled and stored without loss. The valve is a high-quality, metal-to-metal seal, 2/3-turn valve with metal diaphragms to prevent sample adsorption for more accurate results. Both stainless-steel and Siltek-treated valves are available in both the 2-port and 3-port configurations. Each canister is slightly pressurized with contaminant-free nitrogen prior to shipment.

Whether you are sampling for TO-14A, TO-15, TO-15A, or reactive sulfur compounds, SilcoCan canisters are your best choice for inertness. In Tedlar bags, the stability of low-level (100 ppbv) sulfur volatile organic compounds (VOCs) is poor, even within 24 hours of sampling. Sulfur compounds react with the metal surface in electropolished canisters, so they are unsuitable for collecting and storing low-level sulfur VOCs. SilcoCan air sampling canisters, which feature a Siltek-treated surface, offer excellent storage stability for sulfur VOCs at very low levels (5–20 ppbv), under dry or humid conditions. The versatility of the SilcoCan canister makes it an excellent choice for collecting and storing TO-14A, TO-15, or TO-15A compounds.
