    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…

  • Container, liner, and closure cleaned, assembled, and lot traceable Open-top caps PTFE faced 0.125" silicone septa Cleaned to U.S. EPA Protocol B specifications

  • The innovative design of Restek’s high power crimping tool features interchangeable jaws, so you only need one tool and can purchase crimpers and decappers in the sizes that meet your laboratory’s needs. The separate crimper and decapper jaw sets fit standard lab vial seals that are…

  • Graphite Ferrules Preconditioned to eliminate outgassing. High-purity, high-density graphite. Smoother surface and cleaner edges than conventional graphite ferrules. Contain no binders that can off-gas or adsorb analytes. Stable to 450°C. Vespel/Graphite Ferrules …

  • Unlike brass brushes that can leave a metal residue, these stainless steel tube brushes (3/8-, 3/16-, and 1/4-inch) work well for cleaning dirty collectors, injector ports, and detector ports. The surface brush can be used to remove residue that builds up on metal detector jets and electronic contacts.

  • Oxidation-resistant, chrome-plated Use where you need to reduce the line pressure by 20 psig (138 kPa) or more Same purity protection as high-pressure cylinder regulators

  • Use 1/16-inch, two-hole ferrules with the 1/16-inch capillary inlet adaptor fitting kit (cat.# 27185) Use 1/8-inch, two-hole ferrules with the 1/8-inch capillary inlet adaptor fitting kit (cat.# 20645) Vespel/Graphite Ferrules VG2, 60% Vespel/40% graphite blend offers the best…

  • 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.*…

  • Three-way valves made of solid PTFE with hose nozzles. Resistant to chemicals. Very easy connection thanks to its excellent antifriction properties. Blue handles made of PP. Resistant to compression max. 1 bar Vacuum suitable up to 10 -1 mmHg Autoclavable

  • 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…

  • Pack includes 10 large O-rings and 10 small O-rings.

  • EI (electron ionization) filaments meet or exceed original manufacturer's performance. Every filament is subjected to QC tests, including heat, electrical current, and resistance. Samples from each filament manufacturing lot are installed in an MSD for in situ testing.

  • Treated Hydroguard Deactivated Stainless Steel Tubing Hydroguard deactivation creates a high-density surface that is not readily attacked by aggressive hydrolysis. 304 Grade Stainless Steel and Seamless 316L Stainless Steel—Maximum continuous lengths are: 2,000 ft (1/16" OD),…

  • 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…
