Supercritical Pressure Vessel – EV50

The EV50, the largest vessel in Core Separations’ EV Mini Series, offers a 50 mL volume capacity. Fitted with a 5 µm filter for reliable particulate retention, it provides high-pressure, high-performance capability ideal for research, development, and advanced sample preparation prior to extract analysis.

Designed with usability and safety in mind, the EV Series features an innovative threaded cap and energised sprung seal that allows for quick, tool-free opening and closing—perfect for rapid testing cycles in laboratory environments.

Each vessel is machined from high-strength 17-4PH stainless steel, which is approximately 60% stronger than standard 300 series stainless steels. This strength allows for reduced wall thickness and overall weight, improving thermal conductivity and enhancing heat transfer efficiency—critical for temperature-sensitive extraction and reaction processes.

Maintainence and Repair of our CO2 Pressure Vessels

Although our CO2 vessels have been designed for 10,000’s of pressure cycles, the repeated removal of the head to charge and discharge the pressure vessels contents acts to wear the seal. A regular schedule of maintanence ensures that the CO2 vessels keep working for longer periods and reducing the downtime to your research and production schedules.
