Rheological testing pressure cells

Anton Paar has released a range of pressure cells as an accessory to the MCR Physica Rheometer Series.

In general, most fluids and gels increase their viscosity with increasing pressure because the amount of free volume in the internal structure decreases due to compression. Therefore, measurements carried out with the pressure cell can be useful to investigate process conditions such as crude oil production and pumpability of various dispersions.

To maximise performance the pressure cell range consists of four models. The Standard Pressure Cell (300°C, 150 bar), High Pressure Cell (180°C, 400 bar), Pressure Cell XL for High Sensitivity (80°C, 150 bar) and the Starch Cell with special stirrer (160°C, 30 bar). The pressure cell is an accessory for the cylinder temperature control devices.

The pressure cell is fully closed to the environment and it can either be used as a self-pressurising system or pressurised by using a gas tube or compressor.
