Product code: HPE-200
Pressurizing the sample
The HP200 permit the fine calibration of force inside the DAC’s hydrostatic room and is exerted by a metallic membrane which is inflated with pressurised gas through the capillary. Typically the gas used is helium or nitrogen gas pressure is below 200 bar.
How it works?
The complete membrane DAC system is composed by the Membrane Control Box and the Membrane Diamond Anvil Cell (DAC). The membrane is connected through a stainless steel capillary to the connection. This device allows to regulate the gas pressure in the membrane of the DAC. It is composed by the gas bottle, a pressure regulator, two valves and a pressure meter. Opening the outlet valve serves for releasing pressure while closing the inlet valve allows to disconnect the pressure regulator from the hydraulic circuit of the membrane DAC. In some cases it may be useful to leave the inlet valve open, so to increase pressure. Using the pressure regulator, or to maintain the pressure constant when a small leak is present in the hydraulic circuit or more generally when the pressure in the membrane would naturally decrease and on the contrary the user wants to keep it constant. This last case happens for example when the DAC is cooled and the user wants to maintain a constant pressure. Maintenance: no periodic maintenance is needed. Simply refill the gas bomb when necessary, with a maximum pressure of 200 bar (generally with Helium).
