Plunger Assembly Pressure-Flo Syringe .5ul

The Pressure-Flo high pressure syringe is a tried and true method of taking homogeneous high pressure samples from a cylinder or "bomb". It contains the sample in a calibrated needle with a wire plunger to displace it and PTFE packing to seal it in, permitting injection of the sample directly through the GC septum inlet for convenience and simplicity.
