Description
Technical field
The present invention relates to equipment of chemical industry technical fields, particularly, are related to a kind of Rotary Evaporators, and in particular to a kind of
It can accurately realize the quantitative Rotary Evaporators of fraction.
Background technology
Rotary Evaporators are a kind of extraction experimental facilities that vacuum distillation concentration is carried out to material, are widely used in sample
Scale concentration, in the experiments such as dry, extraction recycling, particularly for a large amount of solvents of flash distillation.Existing Rotary Evaporators are usual
It is made of components such as vacuum extractor, heating unit, condensing unit, rotating devices, the principle of Rotary Evaporators mainly passes through
Electronic equipment controls, and making flask, constant speed rotary makes solvent form film in the case where being most suitable for rotating speed, increases disengagement area, and passes through
Vacuum pump makes evaporation flask be in negative pressure state, and evaporation flask is placed in constant temperature in water-bath or oil bath pan and adds while rotating
Heat, heating temperature are close to the boiling point of the solvent so that solution carries out heating diffusion and evaporates under negative pressure in bottle, realizes solvent
Rapid evaporation.
Existing common Rotary Evaporators can set in use the temperature of heating kettle, the rotating speed of cucurbit and its
Experimenter can accurately determine the amount of charging before height, distillation in water-bath, but in receiving flask in distillation process
Stopping distillation when the amount of concentrate is how many in the amount or cucurbit of fraction but can not accurately determine that this is completely dependent on experimenter
Observation and feel to be determined.In many cases, distillation time is even defined, due to being vacuumized every time since distillation
Can not be identical to time for reaching normal pressure-reduction level is vacuumized, while the sealing in view of being related to Rotary Evaporators
Situation, the simple method for limiting distillation time can not accurately determine the time point that distillation stops.Moreover common receiving flask
It is aryballos, even if the sophisticated experimenter of the height of wherein liquid level rules on bottle determines the time for stopping distillation
The point also at least error of more than 1.5mL, this can seriously affect judgement of the researcher for doing and being evaporated under reduced pressure for distillation end point.
Especially when feeding the sample taken at random for nature, the indexs such as various composition of charging, fraction or concentrate will distill
It is measured after experiment, but the ratio between the ratio between yield namely fraction amount and inlet amount or concentration liquid measure and inlet amount can not protect
Hold precisely consistent, this causes the distillation result of different batches that can not carry out lateral comparison.Because experimenter had often both wished
Yield is high and wishes that fraction quality is good, and though be often present with that yield is high in real work the quality index of fraction not
Although the higher situation of the quality index of height or low yield but fraction, these situations are for quality index more than one
Situation is then more difficult to judge.So for roto-vap operation, the quantitative control of fraction how is realized exactly and is put
Liquid, for ensuring the quality index of more each fraction and same distillation sample difference distillation stage on the basis of yield is consistent
The performance difference of fraction has great importance.
