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 pressurised with contaminant-free nitrogen prior to shipment.

• Siltek-treated canister with optional Siltek-treated valve offers unsurpassed inertness, even for sulphur-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 mbar vacuum/pressure gauge (other gauges available)

  Featuring the proven long life, leak-free performance, and effortless operation of RAVE+ valves

Whether you are sampling for TO-14A, TO-15, TO-15A, or reactive sulphur 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 sulphur VOCs.

SilcoCan air sampling canisters, which feature a Siltek-treated surface, offer excellent storage stability for sulphur VOCs at very low levels (5 to 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.
