Capillary Pressure Refrigerated Centrifuge

Manufacturer: Vinci Technologies
Model Number: RC4500

The RC4500 is a refrigerated centrifuge modified to enable rapid determination of capillary pressure characteristics at atmospheric and/or overburden pressures on six core samples simultaneously. It can also be utilized for rapid sample preparation to restore state conditions for subsequent testing in various test equipment. Custom designed sample chambers offer the ability to spin core plug samples up to 1.5 inches in diameter at rotational speeds up to 4,500 RPM. It includes a rotor and drainage cells which can accommodate either 1”, or 1.5” diameter cores. A digital speed control with the ability to ramp speeds at specified intervals and a precision temperature control system is included. An over-temperature setpoint stops the centrifuge if the temperature exceeds the setpoint by a specified value. The system is also equipped with a sensor for rotor imbalance. It is equipped with a digital camera system that allows to user to measure the displaced fluid volumes in each of the cells sequentially.
