Title:
ROTARY EVAPORATOR FOR ACCURATELY AND QUANTITATIVELY RECOVERING MULTIPLE SOLVENTS OR CONCENTRATING MULTIPLE SAMPLES AT ONE TIME
Document Type and Number:
WIPO Patent Application WO/2021/047537
Kind Code:
A1
Abstract:
A rotary evaporator for accurately and quantitatively recovering multiple solvents or concentrating multiple samples at one time, one original distillation flask being changed to at least two, the distillation flasks being connected in series and rotated along the same axis, a bracket (13) supporting under the distillation flasks; one original axis of rotation being changed into two, each axis of rotation being provided with one or at least two distillation flasks connected in series, the number of condensers and collection bottles being increased correspondingly with the number of distillation flasks; if the number of distillation flasks on one axis of rotation is more than one, a connector (9) is arranged between the condenser and a transmission body (3), the distillation flask being heated using an electric heating belt (10), the collection bottle can be changed to a collector (6) with the function of accurately quantifying and discharging the fractions, and the distillation flasks can be connected to a concentrated liquid quantitative assembly (7), to implement accurate and quantitative recovery of multiple solvents or concentration of multiple samples at one time.
