The Piston Type Sample Cylinder PDC is a shipping bottle designed to transport and store pressurized samples, especially hydrocarbon samples. To separate the sample fluid from a secondary driving fluid, the bottles are equipped with a floating piston. The piston has a single O-ring seal and a wear ring and is designed to minimize friction and reduce pressure load. A mixing ball is incorporated.

The bottles are designed with a minimum of dead volume. The two end caps are sealed with double o-ring seals and back-up rings. Both end caps are held in place by strong circlips. Valve protectors on both ends protect the valves during handling and transportation. An aluminum transportation box is available.

Right angle needle valves with 1/4” NPT female port connections are fitted to the 10,000 psi cylinders. A special valve is fit into the sample side which allows evacuation of the cylinder.

7/16” female port threads are machined into the end caps of the 15,000 psi cylinders.
