Diacell® OmniDAC

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

[Formerly WCM-7]

Product Description

Based on the OptiDAC Series' characteristics, the Diacell® OmniDAC 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 Diacell® OmniDAC can be equipped (as an option) with an internal ring heater enabling the heating of the sample to about 600°C.

The gas membrane drive requires, additionally, the Diacell® GM Controller unit 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.


The Diacell® OmniDAC was designed for both X-ray diffraction and optical studies at room and high-temperatures.
