Abstract
The utility model discloses a distillation structure for on rotatory evaporimeter, including many manifolds, centrifuging tube, annular plug and rotatory bottle, the interior anchor ring suit of annular plug is on the centrifuging tube opening, and a plurality of axial bleeder vents have been seted up to the outer anchor ring of annular plug and the connector medial surface sealing connection of many manifolds on annular plug, and rotatory bottle is pressed from both sides through an interface and is fixed on the many manifolds connector outside and make the centrifuging tube arrange in rotatory bottle. The utility model discloses simple structure is provided with the centrifuging tube that is used for placing the micro-sample in rotatory bottle, through evacuation and heating rotatory bottle, distills the volatile liquid in the centrifuging tube, realizes the purpose that the micro-sample evaporates soon. The extract obtained after rotary evaporation is arranged at the bottom of a centrifugal tube, so that the extract is convenient to store, and the extract can be completely and fully dissolved when trace amount of the extract is dissolved.
Description
Technical Field
The utility model belongs to the technical field of the laboratory glassware technique and specifically relates to a distillation structure for on rotatory evaporimeter.
Background
At present, a vacuum rotary evaporator is a common instrument used in a laboratory, and is mainly used for continuously distilling a volatile solvent under a reduced pressure condition so as to extract compounds in the solvent. The distillation device mainly comprises a motor, a rotary bottle, a heating pot, a condenser pipe and the like, is mainly used for continuously distilling volatile solvents under the reduced pressure condition, and is applied to the fields of chemistry, chemical engineering, biological medicine and the like.
The rotary bottle of the existing rotary evaporator is mainly used for extracting a sample with a large solvent amount, and is not suitable for a sample with a trace amount of solvent. The main reason is that after the trace solvent is evaporated to dryness in the vacuum rotary evaporator, the compound remains on the inner wall of the rotary bottle due to the large volume of the rotary bottle, and the extracted compound is difficult to completely dissolve in the trace solvent, so that the compound is difficult to store, and a great error is caused in the next experiment.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned prior art not enough, provide a simple structure's a distillation structure for on rotatory evaporimeter, use this distillation structure, can the evaporation to dryness trace liquid soon.
In order to realize the purpose, the utility model discloses a technical scheme is: a distillation structure for a rotary evaporator, comprising: the centrifugal tube comprises a multi-manifold tube, a centrifugal tube, an annular rubber plug and a rotary bottle, wherein the inner annular surface of the annular rubber plug is sleeved on the opening of the centrifugal tube, the outer annular surface of the annular rubber plug is hermetically connected with the inner side surface of a connecting port of the multi-manifold tube, a plurality of axial air holes are formed in the annular rubber plug, and the rotary bottle is fixed on the outer side of the connecting port of the multi-manifold tube through a connector clamp and enables the centrifugal tube to be arranged in.
Furthermore, the multi-manifold is provided with a plurality of connecting ports, and each connecting port is connected with one centrifuge tube and one rotary bottle.
Further, the centrifuge tube has a capacity of 10 ml. The volume of the spinner flask was 100 ml.
The utility model has the advantages that: simple structure is provided with the centrifuging tube that is used for placing the micro-sample in rotatory bottle, through heating rotatory bottle, under vacuum state, distills out the interior volatile liquid of centrifuging tube, realizes the purpose that the micro-sample evaporates soon. The extract obtained after rotary evaporation is arranged at the bottom of a centrifugal tube, so that the extract is convenient to store, and the extract can be completely and fully dissolved when trace amount of the extract is dissolved.

The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an exploded view of the present invention.
Fig. 3 is a schematic view of the ring-shaped rubber plug of the present invention.
Detailed Description
As shown in fig. 1-3, the utility model relates to a distillation structure for rotary evaporator, which comprises a manifold 1, a centrifuge tube 2, an annular rubber plug 3 and a rotary bottle 4. The inner ring surface of the annular rubber plug 3 is sleeved on the opening of the centrifuge tube 2, the outer ring surface of the annular rubber plug 3 is hermetically connected with the inner side surface of the connecting port 11 of the multi-manifold 1, and a plurality of axial air holes 5 are formed in the annular rubber plug 3. The spinner flask 4 is held on the outside of the connection port 11 of the manifold 1 by a port clamp 6 and the centrifuge tube is placed inside the spinner flask.
Furthermore, the multi-manifold is provided with a plurality of connecting ports, and each connecting port is connected with one centrifuge tube and one rotary bottle.
Further, the centrifuge tube has a capacity of 10 ml. The volume of the spinner flask was 100 ml.
During the use, put into the centrifuge tube with micro-sample (can be less than 1 ml), assemble back with manifold 1, centrifuging tube 2, annular plug 3 and rotatory bottle 4 again, install again and evaporate the operation soon on the rotatory evaporimeter.
In addition, when a large amount of samples and micro-samples need to be processed simultaneously, the large amount of samples can be placed in the rotary bottle, the micro-samples are placed in the centrifugal tube, and rotary evaporation is carried out simultaneously, so that the efficiency is improved.
The above description is only for the purpose of illustrating the technical solutions of the present invention, and the simple modification or equivalent replacement of the technical solutions of the present invention by those of ordinary skill in the art does not depart from the spirit and scope of the technical solutions of the present invention.
