Gas Membrane-Driven DAC for X-Ray Applications
Part of the Diacell Bragg series
[Formerly DXR-GM(B)]
Product Description
The Diacell® Bragg-LT(G) & Bragg-LT(G) Plus are the cryogenic versions of the Bragg-(G) and Bragg-(G) Plus cells, respectively. Diacell® Bragg-LT(G) uses standard design anvils and beryllium support plates, whereas the Bragg-LT(G) Plus uses conical tungsten carbide support plates and conical anvils.
Naturally, it is also possible to convert a Bragg-LT(G) to a Bragg-LT(G) Plus (and vice-versa) by replacing the hemisphere, lower plate, anvil support plates and anvils. Please enquiry for more details.
The Diacell® Bragg-LT(G) & Bragg-LT(G) Plus are suitable for use in several commercial cryostats. Because these cells are gas membrane-driven their use is limited to not less than 6 K due to the gas-to-solid phase change in He at 5.2 K when at 200 bar gas pressure.
Note: If the diamond anvil cell is to be used a low temperature, a low temperature relief valve will need to be fitted on the gas line. This low temperature relief is available from Almax easyLab alongside our GM or iGM controllers option.
Applications
For X-Ray diffraction and related work at low temperatures.
