Your specialist for solvents

Martin Christ gained experience in the field of solvent freeze drying at an early stage. Today, in addition to the high-performance Alpha 3-4 LSCbasic laboratory freeze dryer, two pilot freeze dryers are available that allow optimum drying of end products with highly concentrated solvents.

Based on experience, a simplified classification of the solvents normally used in freeze drying into "low" - "medium" - "high" has been developed. This makes it quick and easy to decide which freeze dryer configuration is the right solution for which solvent concentration.
