Introduce Your Sampling Canisters to Restek® Air Valve Excellence (RAVE™)
30 Oct 2014
The new RAVE™ valve brings proven long life, leak-free performance, and effortless operation to your air sampling canisters. This durable design has been engineered to exceed 15,000 cycles—and every valve is leak-tested with helium to 1x10-6 mL/sec before it leaves our facility. The W-type valve seats are work-hardened to enhance damage resistance, while the wetted surfaces contain no moving parts. And because convenient, reliable field use isn't just about withstanding the rigors of harsh environments, the RAVE™ valve achieves full closure with a quick twist of the fingers (only 10 in-lb) and is easy to access, even for big hands or when wearing bulky gloves.
Now standard on our full line of SilcoCan®, TO-Can®, and miniature air sampling canisters, these newly redesigned, American-made valves are also ideal for upgrading existing canisters. Rugged stainless steel RAVE™ valves can be ordered with Siltek® treatment for added inertness and either 2 or 3 ports to accommodate an optional gauge. Plus, diaphragm rebuild kits are available to further extend the life of these long-lasting air valves. Turn to your trusted partner for air sampling and chromatography—order Restek® Air Valve Excellence for your air sampling canisters today.

SilcoCan® Air Sampling Canisters with RAVE™ Valve
Restek Corp.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 RAVE™ 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 RAVE™ 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 monitoring for TO-14A, TO-15, 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 or TO-15 compounds.Features: 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 prevent sample adsorption for more-accurate results. Canisters and valves made of 304 and 316 stainless steel to withstand the rigors of field work. 2-port or 3-port valve 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 the new RAVE™ valve.
