Scientists working in the drug discovery environment need optimized sample preparation capabilities. The HT-4X centrifugal evaporator from Genevac makes demanding applications routine. Corrosive vapours such as trifluoroacetic acid may be removed by the standard system and an inert purge option allows high safety evaporation of flammable solvents. The device can also be used to achieve high-speed lyophilisation of HPLC fractions and solvents used for reformatting samples. A built-in dual chamber refrigerated condenser accelerates the speed of evaporation, and efficient chamber cooling between runs is particularly useful to protect thermally sensitive samples when run immediately after higher boiling point solvents.
