Diacell® VivoDAC (B-Grade)
Raman Spectroscopy, Pmax = 2 GPa, Tmax = 500 K, WD = 6 mm, A = 100°
- The Diacell® VivoDAC is a unique cell for pressure range up to 2 GPa
- Pressure generation is obtained by the combination of a diamond anvil and a Boehler-Almax diamond window. This window, with its 100° opening is used as observation port
- The Diacell® VivoDAC has a very high numerical aperture of 0.77 and a very short working distance of 6 mm. It is ideal for microscopic imagining work of biological samples
- The gas membrane driven pressure mechanism allows the pressure variation within the cell, whilst the experimental set-up is mounted on the microscope stage
- An optional band heater will enable high temperature sample analysis up to 500 K
- This cell is fitted as standard with type IIas Raman ultra-low fluorescence diamond anvil and window

FAQs
What is the maximum pressure I can achieve with the VivoDAC ?
This DAC combines a large culet (1.20 mm) Diacell® design anvil with a Boehler-Almax design diamond window. These characteristics offer a very wide observation angle for optical measurements with a maximum pressure limited to 2 GPa (*).
(*) The Pmax values are only indicative. The maximum pressure achievable with a DAC is influenced by many others experimental parameters, like the gasket characteristics (material, thickness and hole size) or the pressure transmitting medium.
