Diacell® CryoDAC-ST

Micro-spectroscopy, Pmax = 30 GPa, Tmin = 77 K, WD = 8.5 mm, A = 52°

Diacell® CryoDAC Series

Specially engineered to fit seamlessly onto the sample holder of the Janis ST-500 Cryostat
The height of this DAC and the very short working distance ensure that the sample is located very close to the observing top window of the cryostat
The cell was originally designed for micro-Raman measurements but it is also suitable for any other micro-spectroscopy technique
The Diacell® ST-DAC System is the turn-key version including both CryoDAC-ST and the Janis ST-500 Cryostat
The Diacell® CryoDAC-ST has a numerical aperture of 0.44 and it enables electrical work via its side ports
Maximum pressures of up to above 30 GPa may be obtained with Diacell® CryoDAC-ST

SKU: A81200

Description

The Diacell® CryoDAC-ST was originally designed for micro-Raman work in the continuous flow cryostat, Janis ST-500. However, this cell can also be used for other micro-spectroscopy techniques, such as imaging and high resolution photoluminescence under high pressure. Provisions have also been made to enable electrical work.

The Diacell® cryoDAC-ST has been engineered to fit seamlessly onto the sample mount of the Janis ST-500. For more information about this specific microscopy cryostat, please refer to Janis’ webpage.

You can see the cell mounted in the cryostat on the Diacell® ST-DAC System.

FAQs

What is the maximum pressure I can achieve with the CryoDAC-ST and a given culet size?

Culet size (µm)	200	300	400	500	600	800	1000
Pmax (GPa) (*)	N/A	48	31	20	14	8	5

(*) 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.
