Gas / Liquid Syringes - Series A

Turn the nosepiece counterclockwise two turns and the syringe's integral sample storage valve is closed. Insert the needle through the septum, then start pushing the plunger as you turn the nosepiece clockwise.

Carrier backflushing is eliminated, resulting in sharper peaks and better separations. When the plunger is fully depressed, the plunger face comes into firm, flush contact with the bottom of the front packing, forcing essentially all of the sample out - there is virtually no compressable dead volume remaining. The very small internal diameter of the needle also contributes to the dead volume minimization.

In addition to the characteristics which make it unique, the Series A gas syringe has all the standard Pressure-Lok features such as a PTFE plunger tip, PTFE-sealed needle, and ultrasmooth bore. The modular construction allows quick disassembly for parts cleaning or replacement.
