SGE manufactures a wide range of HPLC syringes for Rheodyne, Valco and Waters syringe-loading sample valves. The syringes are fitted with a special dome-tipped removable needle to prevent needle seal damage in the valve and are of a specific length to avoid rotor damage. A low cost of 10 µL syringe, with fixed needle and replaceable plunger, is available for all valves.
