Beneficial effects of the present invention:
1. one bucket is made up of dosing bucket and liquid flowing tube, dosing bucket is used for preparing liquid, liquid flowing tube is used for measuring liquid, liquid flowing tube top is cylinder, thickness is identical up and down, cylindrical portions is inserted in junction sealing by fusing in dosing bucket, make cylindrical portions in dosing bucket, part is outside dosing bucket, have both and overcome in inner or outer shortcoming in inner or outer advantage, such as, cylinder is completely in dosing bucket, it is unfavorable for the demarcation of liquid volume in cylinder, also it is unfavorable for that cylinder is observed, cylinder is completely outside dosing bucket, it is unfavorable for stablizing of structure, ultrasonic when being also unfavorable for ultrasound procedure it is delivered to cylinder by dosing bucket, the structure that this part is inserted in also achieves cylinder and reads while dosing liquid in bucket volume while avoiding disadvantages mentioned above.Cylinder bottom surface height compared with dosing bucket is identical, and upper bottom surface cylinder, less than the placement of dosing bucket, beneficially device, the beneficially setting of scale, can cover cylinder to dosing bucket configuration dome simultaneously.Thus, point mouth height is less than dosing bucket.Liquid is facilitated to flow into liquid flowing tube.The volume of more than 2/3rds of cylinder is inserted in dosing bucket, plays the advantage being inserted in structure to the full extent.
2. point mouth arranges bleeder valve, and the either on or off of bleeder valve determines taking and the liquid of quantitative fetching of liquid.
3. the setting of communicating pipe achieves the UNICOM of dosing bucket and liquid flowing tube.The on an off arranged for regulating communicating pipe of coupling cock.
4. dosing bucket sidewall arranges dosing bucket opening, and sidewall opening obtains the liquid of more homogenizing, it is to avoid bottom opening regional area there may be uneven liquid inflow liquid flowing tube affects the accuracy of titer configuration.On the other hand, difference in height, beneficially liquid can be formed with point mouth opening and flow into liquid flowing tube.
5. the setting of point mouth opening makes liquid first fill point mouth, is then upwardly into cylinder, bubble occurs, affect the volume that liquid measures, finally affect the accuracy of titer configuration in effectively preventing point mouth.Point mouth inwall is the curved surface tilted, and thus point mouth opening is also the curved surface tilted, and liquid, when flowing into liquid flowing tube, will not leave bubble at Jian Zuichu, so that it is more accurate to measure liquid.
6. point mouth opening is above bleeder valve, and when closing bleeder valve, liquid flows into liquid flowing tube, until liquid level is equal.
7. cylinder part outside dosing bucket arranges scale, beneficially accurately the measuring of volume.It is 0 that cylinder bottom surface arranges scale.
8. dosing bucket marks the volume multiple proportions relation with liquid flowing tube, the scale on cylinder can be utilized to be multiplied by multiple proportions relation to determine the volume of dosing liquid in bucket, when liquid level is when dosing bucket is equal with liquid flowing tube, then the scale reading liquid flowing tube is multiplied by the volume of the i.e. available more accurately dosing liquid in bucket of multiple proportions relation.
9. the design of mounting makes liquid will not flow out from cylinder part dosing bucket, and the design of breach can also communicate with dosing bucket after making cylinder be covered by the dome of dosing bucket, keeps cylinder identical with the air pressure in dosing bucket.Can also enable that the liquid in cylinder is jagged time too much to flow out.When scrubbing, under mounting, region is not easy to brush, and indentation, there position is less than mounting, can be inserted hairbrush by breach and complete to scrub work.
10. the sealing by fusing that connects through of device standing part realizes.
The part sealing glass baffle plate that 11. cylinder bottom surfaces are inserted in dosing bucket, cylinder bottom surface part outside dosing bucket connects point mouth, the volume making point mouth portion reduces accordingly, when reduction measures liquid, liquid is in storage herein, thus avoid the waste of liquid, the design of this glass baffle plate actually makes the bottom surface of dosing bucket become a complete circle, the beneficially Stability Analysis of Structures of glass device, simplifies processing technology.
12. stands provide one bucket supporting role, one bucket is enable to be arranged above and below multiple, multiple one buckets cooperate and can efficiently complete the configuration of solution and multiple doubling dilution thereof together, disposably complete the configuration of multiple concentration, the volume of upper solution and the volume of diluent that need according to the concentration of solution in the one bucket of upper strata and the solution concentration calculating of needs configuration configure lower floor's solution, gradient dilution can also be carried out by calculating at solution used and needing to arrange one or more intermediate concentration between the solution configured.
13. table tops arrange mechanical agitation and ultrasonic generator, and stirring paddle makes dosing liquid in bucket mix rapidly, and the ultrasonic liquid mixing that is also beneficial to is uniform, and the discharge of bubble in can help to dosing bucket and measuring bucket, it is also possible to use when scrubbing one bucket.Ultrasonic probe that integrally bucket is arranged by upper strata table top provides ultrasonic, and the stirring paddle that integrally bucket is arranged by upper strata table top provides stirring, and ultrasonic probe and stirring paddle stretch in solution, makes ultrasonic and stirring intensity evenly, improves ultrasonic and mixing effect.
The setting of 14. utensil receiving openings provides the receiving space of point mouth, makes device internal combination more reasonable.
15. table tops are rotationally connected with column, can regulate the position between table top, make device more flexible, play device effect to a greater extent.
16. mechanical agitation and ultrasonic generator, by control panel control, conveniently operate.
Arranging one section of silica gel tube 17. communicating pipes, silica gel tube is connected on peristaltic pump, and dosing bucket opening arranges semipermeable membrane so that peristaltic pump realizes the filtration of semipermeable membrane while realizing providing solution.Semipermeable membrane can arrange different apertures, it is achieved different filtrations, such as: the removal of impurity, bacteriological filtration etc..
