Supercritical Pressure Vessel – EV25

The EV25, part of Core Separations’ EV Mini Series, features a 25 mL volume capacity ideal for small-scale extractions, reactions, and method development. Equipped with a 5 µm filter for effective particulate retention, it delivers high-pressure, high-performance operation perfectly suited for research, pilot testing, and precise sample preparation prior to analytical evaluation.

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.
