  • Peek Sample Loops

    Agilent Technologies

    … Concentrated nitric acid and sulfuric acid weaken PEEK tubing THF, methylene chloride and DMSO cause PEEK to swell Actual volumes can differ because of tolerance of tubing bore Accuracy of large PEEK loops is ±14%, intermediate loops ±21%, small loops ±65%

  • Stainless Steel Sample Loops

    Agilent Technologies

    Sample loops for Rheodyne 7725 Series and 7125 Series valves are not interchangeable due to the change in port angle Actual volumes can differ due to tolerance of metal tubing bore Accuracy of large metal loops is ±5%, intermediate loops ±10%, small loops ±30%

  • PEEKsil™ Injection Loop

    SGE

    …and sample rinse times Reduced sample loss due to shear or adsorption Maximum operating pressures are 3000psi for 10µL, and 20µL loops Supplied with PEEKsil™ tubing and two sets of Stainless Steel Hexnuts™ with PEEK ferrule fittings Compatible with most valves…

  • Rheodyne Series 7725i

    Agilent Technologies

    Stainless steel Most popular injection valve for analytical HPLC Loops range from 1 µl to 5 ml (20 µl loop installed) Built in position sensing switch provides the LC with reproducible start signal Selected as Agilent 1050 and 1100 manual injectors

  • Injection Valve Replacement Parts

    Agilent Technologies

    Rotor seals wear with use and need routine replacement Stators only need replacement if the ports are damaged PEEK rotor seals are incompatible with concentrated nitric and sulfuric acids

  • Rheodyne Series 3725i

    Agilent Technologies

    Large sample volumes, high flow rates and preparative columns 100 µl to 20 ml (10 ml loop installed) For biomolecules, the 3725i has PEEK materials

  • Mininert® Valve, screw thread for use with 20/400 mm thread

    MilliporeSigma

    Application Mininert valves are leak-tight closures for vials and other containers. They are available in both crimp and screw thread versions. Only PTFE and glass are in contact with the contents of the container. They are the ideal closure for the following applications: calibration…

  • Rheodyne 7725 Injection Valve

    PerkinElmer

    HPLC. They can inject from 1 mL to 5 mL with high accuracy and precision. These versatile injectors can use either of two methods for loading the sample loop. The partial filling method uses the syringe to measure the sample volume. It lets you vary volume easily without having to change the loop,

  • Rheodyne 9725 PEEK Injection Valve for Series 200 Autosampler

    PerkinElmer

    …phases. It applies to both HPLC and soft gel chromatography, and is also suitable for ion chromatography, since metal does not contact the mobile phase. This injector is identical to the Model 7725 stainless steel injector, but the materials are different: the loop, nuts, ferrules, stator, and…

  • Rheodyne Series 9725i

    Agilent Technologies

    PEEK flow path is perfect for biomolecules?sample does not contact metal Similar features as 7725i, including the “make-before-break” design

  • Switching Valve Supplies

    Agilent Technologies

    A set of valve types specially designed for the Agilent 1100/1200 Series HPLC system allows you to extend your HPLC applications. More flexibility in solvent selection and column selection New automation capabilities in sample preparation Increased sample throughput through…
