Unlike many of the more complex designs it is much easier to see the phase change at the critical point. The rapid ingress of CO 2 helps prevents pre-drying of samples. A certificate is issued. A pressure bursting disc is fitted to safeguard against misuse. Sample handling - optional sample holders for coverslips and TEM grids.
Porous pots are available for very small samples.
The design of the E3000 features a horizontal pressure chamber measuring 30.1mm internal diameter x 82mm in length. The chamber has a water jacket for temperature control and specimens are introduced via a removable rear door. The front of the chamber is fitted with a 25mm diameter window which permits easy viewing of the liquid level. Dial gauges display pressure in the chamber and the temperature of water circulating through the jacket. Three pressure valves permit easy connection to the liquid CO 2 cylinder, liquid agitation and venting of the chamber.
