Supercritical Pressure Vessel – EV1K1L

The EVK1LK, part of Core Separations’ EV Ultra-High-Pressure Series, is a 1 L extraction and reaction vessel engineered to operate at pressures up to 1100 bar. Constructed from high-strength 17-4PH stainless steel, it delivers exceptional durability and safety under extreme conditions. Designed for ultra-high-pressure CO₂ processing, the EVK1LK enables enhanced solubility, mass-transfer, and reaction control beyond conventional supercritical ranges, making it ideal for advanced research, material modification, and high-density CO₂ applications.

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.
