Diacell® OmniDAC-LT

Gas Membrane Driven DAC for Optical and X-Ray
Part of the Diacell OmniDAC series

[Formerly WCM-7(B)]

Product Description

This is the cryogenic version of the Diacell® OmniDAC and differs from it only in being made of BeCu alloy.
Based on the OptiDAC Series' characteristics, the Diacell® OmniDAC-LT was designed for both X-ray diffraction and optical studies taking advantage of the gas membrane drive mechanism.  Extended lateral sight holes allow the observation of scatter at directions normal to the cell axis. 

The gas membrane drive requires, additionally, the Diacell® GM Controller containing valves, couplings, pressure measurement and digital display modules. A quick-release Swagelok coupling allows ready disconnection of the cell from the control box, without loss of 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.


The Diacell® OmniDAC-LT was designed for both X-ray diffraction and optical studies.
