Diacell® μScopeDAC-HT(G)

Gas Membrane-Driven High-Temp. Microscope Cell
Part of the Diacell μScopeDAC series

[Formerly HTMC–HT Microscope Cell]

Product Description

This versatile, gas membrane driven, high-temperature, diamond anvil cell, meets the growing need to reach very high pressures and be compatible with the optical and physical constraints of microscopes.  It is suitable for optical work under FTIR and Raman microscopes and has an internal gasket heater that operates to 600°C.  The cell is supplied fitted with a K-type thermocouple and is suitable for water cooling. 

The Diacell® μScopeDAC-HT(G) is only 25 mm thick along the optical axis, and is symmetrical about the sample.  Thus, the physical distance from the objective to the sample between the diamond anvils is just 12 mm.  This makes the Diacell® μScopeDAC-HT(G) compatible with most, if not all, commercial Raman and FTIR systems.


A large and increasing percentage of optical and spectroscopic observations is now made using microscopes.  In particular, Raman instruments are commonly sold with integral microscopes to enable efficient scattered light collection, as well as to permit Raman mapping of complex samples.  Similarly, FTIR spectrometers are often supplied with reflecting (Cassegrain) microscopes.  The Diacell® μScopeDAC-HT(G) is particularly suited for such applications.
