Abstract
The utility model relates to a laboratory single-stage multipoint automatic extractor which is composed of a box body, a plurality of single-stage automatic extraction units 2 and a control unit. The utility model has the advantages of reasonable and simple structure and high automatization, guarantees accurate measuring results, reduces labor intensity and decreases solvent harm on operators. The extractor can be widely used in liquid-liquid extraction experiments in laboratories.
Description
The utility model relates to a kind of laboratory with liquid-liquid abstraction instrument, particularly relates to the automatic abstraction instrument of a kind of single-stage multiple spot.
As mixing-clarifying chamber, operating personnel build the separatory funnel lid with separatory funnel in laboratory liquid-liquid extraction in the past, and level is rocked before and after holding separatory funnel, regularly open bottle cap and release owing to rock the pressure that produces in the bottle.There is following deficiency in said method: 1, labour intensity is big; 2, operating personnel contact a large amount of solvents for a long time; 3, the artificial disturbance factor is many in the operating process, influences measurement result, and result's repeatability and reliability are low.Therefore have and reduce labor intensity, save time, reduce solvent operating personnel are endangered, and the automatic abstraction instrument of single-stage multiple spot that can reduce evaluated error, good reproducibility there is wide application prospect.
The purpose of this utility model has designed a kind of automatic abstraction instrument of single-stage multiple spot rational in infrastructure for overcoming the deficiencies in the prior art, with guarantee measurement result accurately, reduce labor intensity, reduce solvent operating personnel are endangered.
The utility model comprises casing 1, the automatic extraction cells 2 of a plurality of single-stage and control module 3, and wherein extraction cells 2 distributes and is installed in the casing 1, and control module 3 can be installed on the outer surface of casing 1 so that operation.
Fig. 1 is the automatic extraction cells schematic diagram of the utility model.Fig. 2 is the utility model control module schematic diagram.Fig. 3 is the general illustration with abstraction instrument of four extraction cells of the present utility model.Specify 26S Proteasome Structure and Function of the present utility model below in conjunction with accompanying drawing.
Casing 1 of the present utility model can be made by organic materials such as corrosion resistant plate, galvanized sheet or PVC, and its shape can be suitable shape such as cuboid or square, wherein clamper 4 can be set and carriage 5 fixes extraction cells.Whole abstraction instrument can be placed in the fume hood.
Extraction cells 2 of the present utility model comprises mixing-clarifying chamber 11, mixing-clarifying chamber's loam cake 10, agitator 12 and plug valve 13, and mixing-clarifying chamber 11 and mixing-clarifying chamber's loam cake 10 can connect by thread connection or interference fit.Agitator 12 can be fixed spiral agitators such as two leaves, three leaves or four leaves, also can be the agitator of other type, and agitator connects with motor 6 by shaft joint 8.Mixing-clarifying chamber 11 or its loam cake 10 can communicate with injector 7 by sample introduction-exhaust manifolds 9, the loam cake of injector 7 can be opened pore, when extraction, can add reagent by injector 7, also can open extraction-clarifying chamber's loam cake 10 and directly add, the gas that produces in extraction process can be discharged to avoid mixing-clarifying chamber's internal pressure too high by sample introduction-exhaust manifolds 9.The material of mixing-clarifying chamber 11, mixing-clarifying chamber's loam cake 10, agitator 12 and plug valve 13 can be selected according to the medium of contact, then will select corrosion-resistant material or at its surface-coated preservative substance as the contact corrosion solvent.The optimum of mixing-clarifying chamber 11 is shaped as cylindrical.The agitator of each extraction cells can also can be driven by a motor unification respectively by motor-driven.The quantity of extraction cells can be provided with as required, is generally 1～8, preferred 2～6.Motor and injector can be fixed on the casing.
Control module 3 of the present utility model is decided device 14, sedimentation timer 18 by extracting, stirring speed regulator 19 is formed, and is whip switch group 21,22,23 and hand/automatic switch 20, starting switch 17 and the extraction indicator lamp 15 that power supply indicator 16, each extraction cells can also be set easy to use.Wherein extract timer the extraction time can be set, the sedimentation timer can be provided with the sedimentation time and then report to the police, stir speed regulator and can regulate the rotating speed of agitator to adjust stirring intensity, hand/automatic switch can select manual extraction also can select automatic extraction, starting switch is used to start extraction process, the whip switch group can be controlled the usage quantity of agitator (being extraction cells), can control as the switches set among Fig. 3 and use 1～4 extraction cells.
Abstraction instrument of the present utility model is suitable for carrying out in the laboratory liquid-liquid extraction most and uses.
The automatic abstraction instrument of the utility model is compared with artificial extracting operation, has following advantage: 1, extraction fully; Fixed spiral agitator mixes clarifying chamber high speed rotation at column type, and extract fully mixes.2, artificial evaluated error reduces greatly; Since extraction process be by the fixed spiral agitator of driven by motor at column type mixing-clarifying chamber high speed rotary movement, the extraction degree of sample is consistent, experimental repeatability is good.3, rational in infrastructure, simple, automaticity is high; The utility model can be realized automatic extraction, can carry out a plurality of extraction experiments simultaneously, saves manpower, and labour intensity is low, improves conventional efficient.4, working environment pollutes little; Extraction process can carry out in the enclosed ventilation cupboard, and the staff needn't contact a large amount of solvents for a long time, helps staff's physical and mental health.
