SGE HPLC Syringes

SGE syringes for HPLC are specifically designed for use with Rheodyne and Valco injection valves. Syringes use a 22 gauge (0.028" OD), 51 mm (2 inch) long needle with a square cut (blunt) tip style and no electrotaper.
Selection of the syringe capacity will depend on the injection technique:
  • For partial HPLC injection loop fill, the injection volume should be no greater than half the loop capacity. The injection size sets the injection volume.
  • For complete loop fill, the syringe capacity should be greater than twice the loop volume. A Luer lock syringe fitted with a Rheodyne/Valco Luer lock needle is ideal for this purpose. The loop capacity sets the injection volume.
