For reliable performance, VICI Precision Sampling's patented Pressure-Lok® analytical syringes feature a PTFE plunger tip, stress-formed as a single piece by a special process to ensure a leak-tight seal. The self-lubricating plunger tip stays smooth for the life of the syringe, without the seizing or residue buildup associated with conventional all-metal plungers.

The needle is sealed by a PTFE sleeve or packing that effectively isolates the sample from the needle cement, preventing any dissolution of the adhesive or contamination of the sample. All Pressure-Lok syringes feature ultra-smooth bores, easily replaceable parts, low dead volume, crisp clean graduations, and precision calibration.

    • Gas/Liquid Syringes to suit a wide range of applications, from our popular A and A-2 Series syringes that are perfect for everyday use to syringes with pressurized storage, and our larger Magnum Series syringes for trace sample isolation.
    • Liquid syringes feature reinforced plungers and very small sample sizes (down to .01 µl), with syringes for environmental applications.
    • Liquid syringes for HPLC are designed specifically for use with valves from the major manufacturers of HPLC injectors.
    • High-Pressure Syringes are designed specifically to extract and securely store samples from cylinders up to 500 psi.
    • Autosampler Syringes are replacements for Varian autosamplers.
    • Probes are used to transfer liquid samples from a sample vial to the injection syringe by pressurizing the sample vial with helium.
