Culet size and modification

Choose culet size as a function of:

maximum pressure

culet size

< 5 GPa

> 1.00 mm

5 – 100 GPa

1.00 mm – 0.20 mm

> 100 GPa

<0.20 mm, bevels up to 0.30 mm at 8°

Note: Typical sample space is given by the gasket thickness (typically 0.10 mm or less) and the central hole diameter (typically 30-50% culet size)
 
 
Note: single and double bevels are recommended for very high pressure and electrical measurements.
Note: single bevels around the culet ease the cleaning of the culet and reduce the risk of damage during alignment.
