Diacell® Bragg-(G) & Bragg-(G) Plus

Gas Membrane-Driven DAC for X-Ray Applications 
Part of the Diacell Bragg series

[Formerly DXR-GM]

Product Description

The Diacell® Bragg-(G) is one of our most popular cells being equivalent to the Bragg-(S), but designed to incorporate the gas membrane drive mechanism.  The benefits 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.  Pressures of 100 GPa are achieved with the Bragg-(G) using 200 μm anvil culets.

A more recent addition to the Bragg family is the Bragg-(G) Plus, which incorporates conical anvils.  This means that the beryllium support plates found on the conventional Bragg-(G) cell can be replaced by tungsten carbide ones in the Bragg-(G) Plus.

Naturally, it is also possible to convert a Bragg-(G) to a Bragg-(G) Plus (and vice-versa) by replacing the hemisphere, lower plate, anvil support plates and anvils.  Please enquiry for more details.


This cell is ideal for X-Ray diffraction and related work.
