Core | CO2 Pressure Vessels

Supercritical Pressure Vessels

Core Separations CO2 Pressure Vessels (EV Series) are high pressure, high performance extraction and reaction vessels designed specifically for processing supercritical fluids. Using an innovative threaded cap and energised sprung seal, these vessels are designed to be easily opened and closed without tools while remaining safe whilst under pressure. The vessel bodies are made from high quality 17-4PH stainless steel, 60% stronger than 300 series steel. This reduces the weight and wall thickness of these vessels with the added benefit of improving heat transfer.

1. Material of Construction

Utilisation of 17-4PH with its higher-strength and corrosion resistance compared to 304 and 316SS makes it more cost-effective for higher pressure applications such as supercritical processing.

2. External Threads

Externally threaded body, leaves a smooth internal finish resulting in easy cleaning for both research and cGMP environments.

3. Tool-less design

The two part cap design prevents premature wearing of the energised sprung seal, by allowing the inner cap which houses the seal, to be placed into position without rotation. The threaded outer cap can then be installed without disturbing the seal.

Safety of our Products

Finite Elemental Analysis (FEA)

We take safety of our customers extremely seriously. Our pressure vessels are designed using Section VIII, Division 1 of the ASME Code. This design by formula approach uses a range of rules for calculating wall thicknesses and reinforcement around openings, and other details of a vessel.

To ensure the safety of our products we also apply Finite element analysis (FEA) simulations to predict how our pressure vessels might behave under various extreme conditions and help inform us of predicted life and inspection cycles of our pressure vessels.

The key to safety is knowledge!
