Benchtop evaporator is designed to remove high boiling point solvents and deliver enhanced solvent recovery, thereby improving final drying of stubborn samples and enabling fast lyophilization of HPLC fractions. The high performance scroll pump used with the instrument delivers deeper vacuum than the diaphragm pumps used on other systems in the series. This advance, plus internal enhancements to heat vapour duct and system components, enable the instrument to routinely evaporate challenging high-boiling solvents including DMSO and NMP. In addition these enhancements ensure that such challenging solvents only condense in the instrument’s cold trap, and not anywhere else. The cold trap features automatic defrost and drain technology.
