Abstract
The utility model discloses a kind of high-efficiency rotating evaporimeter conveniently can collecting liquid, comprise water-bath, receiving flask, be fixed on condenser on support and whirligig, it is characterized in that: also comprise the sample cell that solution to be concentrated is housed, described sample cell is connected with whirligig by sample lid, described condenser is connected with three-way pipe, and described three-way pipe is connected with two receiving flasks.Advantage is: condenser is connected with three-way pipe, and the receiving flask that three-way pipe is provided with bleeder valve with two bottoms is connected, when a receiving flask is filled, can swivel tee pipe and three-way valve, continue to use another receiving flask, release the liquid filled simultaneously, easy to operate; Sample cell is connected with whirligig by sample lid, once can concentrate multiple sample simultaneously, saves experimental period.
Description
Technical field
Utility model relates to chemical experimental instrument, specifically a kind of high-efficiency rotating evaporimeter conveniently can collecting liquid.
Background technology
Rotary Evaporators be commonly used to medicine, food, biological industry concentrated, drive distilling flask in continuous rotation mainly through circulator, form rotating thin film and increase disengagement area, accelerate evaporation rate.Negative pressure reduces the boiling point of solvent simultaneously, reduces heating-up temperature, has good protective effect to the heat-sensitive ingredients of concentrate.But in use there is a lot of inconvenience in Rotary Evaporators at present.Such as, when agent is held in evaporation to needs in a large number, receiving flask will soon be filled, a lot of time will be wasted if all taken off at every turn, and accidentally can break bottle into pieces, if what fill in receiving flask is unwanted waste liquid, repeatedly take off and also have peculiar smell and shed, affect environment.In addition, when needing concentrated a small amount of product to beat nuclear-magnetism or carry out other operations, different samples is needed to concentrate one by one, spended time.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of high-efficiency rotating evaporimeter conveniently can collecting liquid, easy to operate, can concentrate multiple low-volume samples simultaneously, saves the plenty of time.
The technical solution adopted in the utility model is: a kind of high-efficiency rotating evaporimeter conveniently can collecting liquid, comprise water-bath, receiving flask, be fixed on condenser on support and whirligig, it is characterized in that: also comprise the sample cell that solution to be concentrated is housed, described sample cell is connected with whirligig by sample lid, described condenser is connected with three-way pipe, and described three-way pipe is connected with two receiving flasks.
The described sample cell that solution to be concentrated is housed is one or more.
Described condenser is the first condenser pipe and the second condenser pipe.
Bleeder valve is provided with bottom described receiving flask.
Described three-way pipe is with three-way valve.
Described water-bath is provided with temperature display and lifting knob.
The utility model advantage is: condenser is connected with three-way pipe, the receiving flask that three-way pipe is provided with bleeder valve with two bottoms is connected, when a receiving flask is filled, and can swivel tee pipe and three-way valve, continue to use another receiving flask, release the liquid filled simultaneously; Sample cell is connected with whirligig by sample lid, once can concentrate multiple sample simultaneously, saves experimental period.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1. the first condenser pipe, 2. charging valve, 3. the second condenser pipe, 4. receiving flask, 5. bleeder valve, 6. water-bath, is 7. elevated knob, 8. temperature display, 9. sample cell, 10. sample lid, 11. supports, 12. air extraction connectors, 13. three-way pipes, 14. power switches, 15. whirligigs, 16. three-way valves.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further described, but protection domain of the present utility model is not limited thereto.
As shown in Figure 1, a kind of high-efficiency rotating evaporimeter conveniently can collecting liquid, comprise water-bath 6, receiving flask 4, be fixed on condenser on support 11 and whirligig 15, also comprise the sample cell 9 that solution to be concentrated is housed, described sample cell 9 is connected with whirligig 15 by sample lid 10, described condenser is connected with three-way pipe 13, and described three-way pipe 13 is connected with two receiving flasks 4.Sample lid can cover multiple sample cell simultaneously, by whirligig driven rotary evaporating solvent.When sample number be less than sample cover the position of the sample cell of setting time, empty sample cell can be placed and enable whole sample lid airtight for sample to be concentrated concentrated.
The described sample cell 9 that solution to be concentrated is housed is one or more.
Described condenser is the first condenser pipe 1 and the second condenser pipe 3.
Bleeder valve 5 is provided with bottom described receiving flask 4.
Described three-way pipe 13 is with three-way valve 16.
Described water-bath 6 is provided with temperature display 8 and lifting knob 7.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And these belong to connotation of the present utility model the apparent change of extending out or variation still belong to protection domain of the present utility model.
