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.

Compatible with 96-well plates from any manufacturer, the Resprep VM-96 is designed for performance and accuracy.

Low-level detection of carbon monoxide (CO) and carbon dioxide (CO 2 ) is critical for many applications. Restek’s methanizer (CH 4 izer) allows ppb-level determination of CO and CO 2 using a cost-effective GC-FID instead of more expensive instrumentation. The methanizer is factory set to 380 °C to ensure efficient and complete conversion of CO and CO 2 to CH 4 , but the operator can easily adjust the temperature as desired with the touch of a button. This unit controls temperatures precisely and reliably to within ± 1 °C of the defined set point and the actual temperature is displayed in real time on an easy-to-read monitor. The Restek methanizer is less cumbersome than other models and is designed for easy installation and fast catalyst tube replacement so you spend more time analyzing samples and less time on maintenance. Key Features: Allows ppb-level GC-FID determination of CO and CO2 without expensive equipment. Precise temperature control ensures complete conversion of CO and CO2 to CH4. Simple, reliable operation—factory-set temperature (380 °C) can be adjusted with just the touch of a button. Convenient installation kit (sold separately) includes all parts needed for quick installation into any Agilent GC. Fast, easy catalyst tube replacement keeps maintenance time to a minimum.




Four straight scoring edges for cutting fused silica tubing and four serrated edges for cutting MXT metal capillary columns.


Pump PM kit for Agilent 1050, 1100, 1200 HPLC Systems. Includes: PTFE frits (2); outlet cap; gold disk seal; active inlet cartridge; piston seals (4); glass solvent filters (2).

Fit all 2.0 mL, 12 x 32 mm, crimp-top vial-based autosamplers.

Use with any standard male luer end SPE cartridges. Inert, PTFE sample guides reduce cross-contamination and carryover. Flexible sample collection rack will accommodate a variety of receiving vessels. Quick vacuum-release valve for better system control. Individual valves allow vacuum control for each cartridge, improving reproducibility.
