The Pressure-Flo® high-pressure syringe is a tried-and-true method of extracting homogeneous high-pressure samples from a cylinder or "bomb". The calibrated needle has a wire plunger to displace the sample, and PTFE packing to seal it in, permitting injection of the sample directly through the GC septum inlet for convenience and simplicity.
The body of the syringe is lightweight for easy handling. It houses a special crimped PTFE packing that seals firmly at pressures in excess of 500 psi even under severe operating conditions. Threads allow the syringe to attach to a cylinder via special bomb adapters.
