  • Glass Bubble Flow Meters

    Agilent Technologies

    Economical 10 or 100 mL These glass bubble flowmeters provide an economical way to monitor gas flow.

  • UHP stainless steel regulators are the standard for ultra-high-purity and corrosion-resistant pressure regulation. They are more easily purged of atmospheric components compared to brass gas regulators, making them ideal for the most demanding applications. Stainless steel is especially useful in…

  • Securely holds up to 36 headspace vials (fits 6, 10, or 20 mL vials). Vials lock in rack for convenient one-handed cap removal. Openings in the bottom of each well facilitate drainage. Alphanumeric indexing on rack simplifies sample identification. Easy to clean and fully autoclavable.*…

  • ADM Flow Meters

    Agilent Technologies

    Accuracy ±3% Operating temperature range: 0 to 45°C for instrument/-70 to 135°C for tubing Calibration traceable to NIST primary standards Measures flow rates from 0.5 to 1000 mL/min Split ratios ADM flowmeters allow most gas measurements with the touch of only…

  • Tedlar® Gas Sampling Bag

    MilliporeSigma

    Tedlar is recommended in several US EPA methods for sampling VOCs and sulfur compounds. Our Tedlar is made from a high-quality 2 mil Tedlar film for superior inertness, impermeability, sample integrity and good recovery data. Our Push Lock Valve (PLV) and seam-sealing process ensure that these bags…

  • Produces square, smooth cuts in 1/16-inch tubing Eliminates tubing distortion Cuts hard or soft copper, aluminum, brass, stainless steel, Monel alloy, or titanium Replaceable cutting wheel

  • On-column injections can be performed only with 0.53 mm ID columns because 26-gauge needles do not fit into the bore of 0.32 mm ID columns, or into the Unliner liner taper. Reduces solvent tailing Versatile—0.53 mm ID version can be used in the direct (DI) or on-column (OC) injection…

  • Parker Balston’s NitroVap-1LV and NitroVap-2LV Nitrogen Generators can provide clean, ultra-dry nitrogen to sample evaporators. These systems offer high nitrogen output flows in a miniature cabinet. The user can activate the manual SLEEP economy mode to eliminate compressed air consumption…

  • Consistently make precise, clean, square cuts with a diamond blade Built-in magnifier to verify square cut Use with 0.25 mm ID to 0.53 mm ID tubing (0.78 mm OD maximum)

  • General purpose single bank vacuum manifold with 4 or 6 ports. Main tube is 1" OD with a serrated hose connection, having the smallest serration 13.5mm and the largest serration 15.5mm, located at either the left or right side for vacuum connection. Ports are 4mm PTFE stopcocks with serrated…

  • Flowmeters that can measure flammable gases are becoming mandatory due to the increased use of hydrogen in chromatography. With its Ex rating, the Restek ProFLOW 6000 meter is designed specifically with explosive and flammable gases in mind. The Restek ProFLOW 6000 is the only flowmeter you…

  • Prevent serious injuries! These holders are designed to prevent free-standing gas cylinders from tipping over and injuring personnel. The cast aluminum holder can be secured to a wall or the side of a work bench. Each mount will secure a cylinder 4-15 inches in diameter.

  • UHP brass regulators are the best choice when using ultra-high purity carrier gas for sensitive GC applications using MS, PID, or ECD detection methods. They feature reduced internal dead-volume relative to stainless steel bodies. The 316L stainless steel diaphragm valve ensures leak-free shutoff.…

  • Nitrogen Generators

    Parker Hannifin

    NitroFlow Lab The Parker Balston® LC-MS NitroFlow Lab is a self-contained membrane nitrogen generator that produces LC-MS grade nitrogen with output pressure to 116 psig. Nitrogen is produced by utilizing a combination of compressors, carefully matched with filtration, and membrane…

  • Usable to 350 °C inlet temperature.* Ultra-low bleed minimizes background signal. New plasma coating eliminates sticking in the injection port. Precision molding ensures consistent, accurate fit. Septa have a CenterGuide design to minimize coring. (Not available on 6 mm, 7 mm, 8 mm,…

  • Polypropylene gas sampling bulbs have polypropylene stopcocks with free-turning Teflon® PTFE plugs. Ends accept 6.4 to 9.5mm (1/4 to 3/8") I.D. tubing Tube body is 5.1cm (2") O.D. x 22.2cm (8-3/4") long Stopcocks are 6.4cm (2-1/2") long Maximum recommended…

  • Graphite Tubes

    Agilent Technologies

    Graphite tubes are quality tested to ensure each batch passes our demanding performance specifications for contamination, sensitivity, precision, electrical resistance and lifetime. Use partitioned tubes for general purpose work and when you need the best detection limits with samples that…

  • Similar to the CG-4440 vacuum manifold, but with BOTH ENDS OF INERT GAS LINE OPEN to permit connection to the gas source and an oil bubbler. Hose connections have a 10mm small serration and a 11mm large serration.

  • Specifically designed for purification of helium in GC-MS systems Traps are packed and conditioned using helium Uses standard single-position base plate

  • The Parker HydroGen Mate DI Water System is specifically designed to provide the high-purity deionized water needed by all models of Parker hydrogen generators. The system is ready to install and is shipped complete with prefiltration cartridge, two DI resin exchange cartridges, final filter, and…

  • Protect your instrument and improve data quality with this powerful pair from Restek. Checking for leaks and verifying flows before you start helps you avoid costly problems later. Restek’s New Leak Detector Redesigned and better than ever, our new leak detector is an essential tool for…

  • Available with uniform frits to ensure maximum purging efficiency Use non-fritted spargers for wastewater samples Manufactured to tight tolerances to ensure a leak-tight seal Designed for use with Tekmar purge-and-trap instruments only

  • These electronic crimpers and decappers have a rechargeable 6.4-volt battery installed. The large battery allows for quick, powerful operation and a faster charge cycle, minimizing downtime. Charging the battery takes thirty minutes to two hours. The universal plug set includes U.S., European, UK,…

  • Available in brass or stainless steel.

  • Tapered for high recovery of contents Work with Mininert sampling valves
