Spectrum* Chromatography Syringes

Double-action syringes feature a double-action plunger guide chamber that eliminates the possibility of bending the plunger. The syringe assembly eliminates heat transfer from the hand to the actual sample area and an extra heavy duty plunger provides a smooth, positive injection stroke. Double-action syringes are supplied with either a fixed (cemented) needle or with a removable needle. The removable needle retains fluid and allows for easy needle replacement. A Teflon* seal in the hub of the needle ensures a liquid and gas-tight assembly. All plungers are hand-assembled to extremely close tolerances to insure exact measurements.
