      RheFlex™ High-Pressure Fittings Thermo Scientific™

      Ensure reliable high-pressure connections by using Thermo Scientific™ RheFlex™ High-Pressure Fittings. These fittings are precision machined from 316 stainless steel to be burr- and contaminant-free.

      GC-Orbitrap™ High Temperature Nut and Ferrule Kit Thermo Scientific™

      Use the Thermo Scientific™ GC-Orbitrap™ High Temperature Nut and Ferrule Kit to obtain leak-free results at high temperature transferline settings on your gas chromatography (GC) Orbitrap. The high-temperature SCP-5000 Vespel ferrules (included) allow continuous operating transferline temperatures of at least 320°C without ferrule deformation or breakdown (common with standard graphite/Vespel ferrules above 280°C), preventing leaks from forming over an extended period of time. The included spring loaded nut ensures a close fit between nut, ferrule and transferline, further preventing leaks from forming.

      Dionex™ IC PEEK Viper™ Kits and Loops Thermo Scientific™

      Achieve consistent low dead volume connections and ensure optimum chromatographic performance for ion chromatography (IC) applications with Thermo Scientific™ Dionex™ IC PEEK Viper™ fitting kits and sample loops. Conventional PEEK fittings can increase dead volume if the ferrule is incorrectly positioned or tubing poorly cut, resulting in reduced efficiencies and poor peak shapes. Dionex IC PEEK Viper fittings provide worry-free, finger-tight connections with virtually zero dead volume. Dionex IC PEEK Viper fittings are easy to use and available in convenient kits tailored specifically to your IC system.

      PEEKsil™ Capillary Tubing Thermo Scientific™

      Get excellent chemical compatibility and very low carryover to improve liquid chromatography (LC) performance using the highly inert Thermo Scientific™ PEEKsil™ Capillary Tubing. Made of precision-bore fused silica tubing coated with a 1/16 in. O.D. PEEK covering, it is capable of withstanding high pressures. PEEKsil tubing is ideal for capillary HPLC and LC-mass spectrometry (MS). The very smooth internal surface ensures excellent flow characteristics and very low carryover. It is compatible with most organic solvents and is usable in most standard chromatography systems.

      SLIPFREE™ HPLC Column Double Connectors Thermo Scientific™

      Ensure excellent column connections and optimal HPLC performance with Thermo Scientific? SLIPFREE? HPLC Column Double Connectors. Compatible with all column end-fittings, these universal, self-adjusting connectors provide leak- and void-free column connections. Fingertight connections up to 10000psi ensure ease of use. They are ideal for supercritical fluid columns (SFC). SLIPFREE connectors are available in a variety of configurations and designs for a broad range of applications.

      PEEK Capillary Tubing Thermo Scientific™

      Use Thermo Scientific™ Rheodyne™ Sample Loops  for your Rheodyne HPLC sample injectors. They are available in stainless steel or biocompatible PEEK.

      GC Liner Sealing Rings for Thermo Scientific™ and Agilent Instruments Thermo Scientific™

      Match the best sealing ring with the injection port liner used in your Thermo Scientific™ or Agilent GC system.

      LinerGOLD™ GC Liners Thermo Scientific™

      Use the gold standard in GC liner performance and consistency. Thermo Scientific™ LinerGOLD™ GC Liners provide enhanced inertness, leading to increased accuracy, sensitivity, and precision in your gas chromatography (GC) analysis. These injection port liners deliver:

      • Increased accuracy and sensitivity in analysis, preventing the loss of sensitive compounds in analysis
      • Lower detection limits when analyzing active and sensitive compounds
      • Excellent reproducibility gives confidence in your results from liner to liner
      • Consistently high level of performance time after time

      SilTite™ Replacement Ferrules , Nuts and Baseplate Seals Thermo Scientific™

      Eliminate leaks with the Thermo Scientific™ SilTite Ferrule, which forms a strong, permanent, airtight seal around the capillary column.

      SLIPFREE? HPLC Column Single Connectors Thermo Scientific™

      Ensure excellent column connections and optimal HPLC performance with Thermo Scientific? SLIPFREE? HPLC Column Single Connectors. Compatible with all column end-fittings, these universal, self-adjusting connectors provide leak- and void-free column connections. Fingertight connections up to 10000psi ensure ease of use. They are ideal for supercritical fluid columns (SFC). SLIPFREE connectors are available in a variety of configurations and designs for a broad range of applications.

      Perfluoro Acid Anhydrides (TFAA, PFAA and HFAA) Acylation Reagents Thermo Scientific™

      Prepare fluoracyl derivatives for GC/MS and for flame ionization and electron-capture detection techniques with the Thermo Scientific? Perfluoro Acid Anhydrides (TFAA, PFAA and HFAA). These reagents react readily with alcohols, phenols, and amines.

      BSTFA Silylation Reagent Thermo Scientific™

      Improve GC analysis with Thermo Scientific™ BSTFA Silylation Reagent. The highly volatile byproducts mono(trimethylsilyl)trifluoroacetamide (BSTFA) and trifluoroacetamide elute with the solvent front to ensure excellent chromatographic separations. This silylation reagent reacts with a wide range of polar compounds and is particularly well suited for the GC analyses of some lower boiling TMS-amino acids and TMS Krebs cycle acids.

      PEEK Sleeves for Fused Silica HPLC Capillary Tubing Thermo Scientific™

      Use Thermo Scientific? PEEK Sleeves for Fused Silica Capillary Tubing to connect capillary tubing to ports designed to receive 1/16 in. O.D. tubing. Chemically inert and flexible, they are capable of withstanding high pressures.

      316 Stainless Steel Capillary Tubing for HPLC Thermo Scientific™

      Use Thermo Scientific? 316 Stainless Steel Capillary Tubing for ultra-high pressure applications. Prefinished, square, burr-free ends and interiors ensure minimum dead volume connections. Cleaned, polished and passivated, it is ready for immediate use. This tubing is not recommended for biological samples.
