  • SilcoCan Air Sampling Canisters with RAVE Valve

    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...

  • ALTEF Gas Sampling Bags

    Sampling bags are a low-cost whole air sampling device for high level VOCs and permanent gases. Several EPA, NIOSH, and OSHA methods exist for bag sampling for a variety of applications: stationary sources emissions; workplace atmospheres; ambient, indoor air quality; and breath analysis. Choose the...

  • Q-sep QuEChERS Extraction Salts

    Free-flowing salts transfer easily and completely. Easy-open packets eliminate the need for a second empty tube for salt transfer. Convenient slim packets fit perfectly into tubes to prevent spills. Ready-to-use tubes, no glassware required. Pre-weighed, ultra-pure extraction salts. Ideal for...

  • Integrated Passive Air Sampling Kits

    Restek's passive air sampling kit incorporates all the hardware necessary to collect air samples and is easy to assemble for field sampling.* The improved filter design greatly reduces the number of potential leak sites. The passive air sampling kit is available in seven sampling flow ranges and in...

    Sampling bags are a low-cost whole air sampling device for high level VOCs and permanent gases. Several EPA, NIOSH, and OSHA methods exist for bag sampling for a variety of applications: stationary sources emissions; workplace atmospheres; ambient, indoor air quality; and breath analysis. Choose the...

  • Miniature Air Sampling Canisters

    These small canisters are designed for controlled sampling, such as personal air sampling, as an alternative to tube and pump samplers. The 1,000 cc canister is suitable for sampling volatile organic compounds in air according to methods TO-14A, TO-15, IP-1A, ASTM 5466, OSHA PV 2120, and NJ DEP Low...

  • Q-sep Bottle Top Solvent Dispenser

    Accurately and precisely dispense liquids for QuEChERS extractions with this versatile pump. A quick, simple adjustment lets you set the output volume anywhere from 2.5 mL to 30 mL per stroke, and the included adaptors will accommodate most reagent bottles. Adjustment knob offers 56 output volume...

  • Sample Cylinders, High Pressure

    Swagelok sample cylinders are made of 304L and 316L stainless steel to resist corrosion and DOT rated to 1,800 and 5,000 psig (TPED cylinders rated to 1,450 and 4,350 psig), which allows sampling at gas wellheads as well as on-site refineries. Each cylinder is hydrostatically tested to at least 5/3...

  • Rocker Vacuum Pumps

    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...

  • Ashcroft Test Gauges

    High-accuracy test gauges are recommended for verifying the vacuum/pressure in canisters before and after sampling. The 6-inch face on the analog gauge allows for easy reading. The digital gauge operates on two AAA batteries and offers an unambiguous readout. Both gauges have an accuracy of +/–...

  • TO-Can Air Sampling Canisters with RAVE Valve

    Optimized for Methods TO-14A, TO-15, IP-1A, ASTM D5466, OSHA PV 2120, and NJ DEP Low Level TO-15 Proprietary electropolished surface maintains compound stability. High-quality, metal-to-metal seal, 2/3-turn valve with stainless steel diaphragms prevent sample adsorption for more-accurate results....

  • Thermal Desorption (TD) Tubes

    High-quality thermal desorption tubes are suitable for ppt to ppm concentrations of volatile organic compounds (VOCs) in ambient, indoor, personal, and industrial hygiene environments. Fit Markes (ULTRA and UNITY), PerkinElmer, and Shimadzu thermal desorbers. Packed tubes come with a report...
