Core P50

Whether looking to deliver liquids into a high pressure autoclave or generate supercritical CO2, the Core Separations P50 can deliver a maximum flow of 50g/min upto 689 bar. Ideal for reactors upto 500mL.

A versatile and precise laboratory pump, purpose-built to support a broad range of applications—from academic research to pharmaceutical development. Designed for the accurate delivery of both liquid CO₂ and other fluids, it incorporates a high-precision stepper motor and can be paired with a flow meter to ensure consistent and controlled dosing.

In addition to flow-based delivery, the pump features a pressure control mode that automatically adjusts flow to achieve or maintain a set pressure within a closed system. This function is ideal for processes requiring stable pressure—such as operating into a fixed-volume reactor or through a fixed nozzle—ensuring reliable performance across dynamic operating conditions.

Balancing high pressure capability, dosing accuracy, and low energy consumption, the pump utilises a proven dual-piston design manufactured in the USA. With over 30 years of experience in high-pressure CO₂ systems, Core Separations delivers a robust and trusted solution for demanding laboratory environments.
