The Diacell® VivoDAC is a membrane-driven cell, allowing good control of pressure over a relatively low pressure range of up to 2 GPa. Instead of the usual opposing anvils found in DACs, the Diacell® VivoDAC uses a diamond anvil and diamond window combination, the latter being the observation port. This important design feature, combined with the pressure range available, makes this DAC ideal for microscopic imaging work in biological applications.
The Diacell® VivoDAC is less than 25 mm thick along the optical axis making it suitable for most, if not all, commercially available microscopy/spectroscopy systems. Furthermore, the physical distance from the objective to the sample through the diamond plate side is merely 8 mm.
The Diacell® VivoDAC with its relative low pressure range (for DAC standards) and very short working distances is particularly suitable for optical measurements with microscope systems. The pressure is generated by a gas membrane which allows the pressure in-situ to be modified continuously whilst the DAC remains under the observing microscope.
