Equipment
Here we present the LPHT-20, our current standard furnace model, designed for LPHT treatment of diamonds in vacuum.
The LPHT-20 can be used for commercial purposes, for example the color treatment of diamonds. It is also a unique research instrument, used for the study of properties of diamond.
