Another business activity since over 15 years is the production of rotational-vacuum-concentrators ("RVC"). Here, the close relationship between the Martin Christ company and Sigma Centrifuges offers obvious advantages in construction and production demands.

The Christ RVC-series is well structured in size and combination with different cooling traps and vacuum pumps. This gives the customer a maximum benefit for every application.
