Specimen Pressure Chamber
1 Pressure gauge
2 Screw-on cover for specimen pressure chamber opening
3 View port to monitor liquid level
Specimen holders or specimen baskets (see section 9) can be inserted into the
specimen pressure chamber. It can be closed with a screw-on cover (1). The front
sight glass (2) allows observation of the level of the transition liquid as well as the
achievement of the critical point.
A cooling coil connected with the cooling unit and a heater built into the specimen
pressure chamber are designed to set the temperature necessary for the critical
point drying process. The control is carried out using a temperature sensor.
A magnetic stirrer system is built into the bottom of the specimen pressure chamber
to mix the liquids during the media exchange. The magnetic stirring rod lies within
the specimen chamber.
A burst membrane protects the specimen pressure chamber from exceeding the
permissible maximum pressure of approx. 150 bar.
