*Note that SNAP DACs with 40 GPa capability have been successfully used on DEMAND although pressures on single crystal samples have not been demonstrated above 10 GPa. If higher pressures than 10 GPa are desired, please contact instrument team. **Note that a maximum of 20 GPa has been demonstrated for single crystal samples. The cells themselves are in principle capable of reaching 100 GPa on powders. If high pressures are of interest, please contact instrument team for discussion.
For more details of each instrument's specifics, refer to instrument home page.
