Diacell® GM Controller
Control Unit for Diacell® Gas Membrane Driven DACs
- The Diacell® GM Controller enable safe, accurate and reproducible gas pressure control
- It is used to control the gas pressure in the membrane driven diamond anvil cells
- The Diacell® GM Controller contains all necessary valves, couplings, pressure measurement and digital display modules
- The controller is also fitted with a quick release Swagelok coupling that allows ready disconnection of the diamond anvil cell from the system, without loss of gas content—and therefore– of in-situ pressure
- The Diacell® GM Controller works off a 24 volt power supply, which is included
- Option: low temperature gas membrane cells in addition require the GM Controller Relief Valve Option for safe operation
Description
The Diacell® GM Controller is the control unit needed for the gas membranes of Diacell® DACs. It contains valves, couplings, pressure measurement and digital display modules. The controller is also fitted with a quick release Swagelok coupling that allows ready disconnection of the cell from the system, without loss of gas content. The GM Controller works off a 24 volt power supply.
Low temperature gas membrane DACs in addition require the GM Controller Relief Valve Option for safe operation.
Almax easyLab makes extensive use of gas membranes to drive cell pistons in our Diacell® range of DACs. A gas membrane is rather like a motor tyre with one very thin wall. When pressurized internally, this wall bulges. Advantages of this type of drive include the ability to apply very small incremental loads, remote operation, and the achievement of higher pressures due to absence of friction associated with bolts. Almax easyLab are able to supply both additional gas membrane drives and control boxes.
A video showing how the make the connections between the GM controller and a diamond anvils cell gas membrane is available on Almax easyLab’s YouTube channel.
