Abstract

See full text

A rotary evaporator for accurately and quantitatively recovering multiple solvents or concentrating multiple samples at once is provided. At least two distillation flasks are included. The distillation flasks are connected in sequence and rotated along the same axis. A bracket is disposed at the lower part between the distillation flasks for support. Instead of one rotation axis, at least two axes are included. Each rotation axis is provided with at least one distillation flask. The number of condensers and the number of collecting flasks increase correspondingly with the number of distillation flasks. If the number of distillation flasks on one rotation axis is greater than 1, a connector is disposed between the condenser and a transmitter. The collecting flask can be changed into a collector with the function of accurately quantitating and discharging distillates. Each distillation flask may be connected to a concentrated liquid quantitative assembly.
