Introduction The Biotage TurboVap LV Evaporator is a microprocessorcontrolled evaporator that provides simultaneous, automated concentration of multiple samples, unattended operation, convenience, and speed. The TurboVap LV can simultaneously process up to 50 samples in many popular test tube, centrifuge tube, and micro-centrifuge tube sizes. This section of the manual describes the features of the TurboVap LV evaporator.

Gas Vortex Shearing Action The evaporator uses a patented “gas vortex shearing action” that maintains high evaporation rates regardless of sample height in the tubes. A helical flow of air is created by the stream of gas directed into each sample tube. The helical flow sets up a vortexing action that provides for sample homogeneity and continuous rinsing of the tube wall. The vapor-laden gas exits via an unobstructed path up the center portion of the tubes and is removed by an exhaust fan to the exhaust port in the back of the unit. From the exhaust port, the exhaust duct is routed through the vent tubing to a suitable, outsidevent location. Gas Nozzle
