Description
Technical field
The present invention relates to a kind of super-clean bench magnetic base test tube, funnel, suction pipe, pipettor, injector holder.
Background technology
There is provided in the scientific experiment of gnotobasis at super-clean bench, plastic miniature test tube (hereinafter referred to as test tube) with cover, funnel, suction pipe, pipettor and syringe are conventional experimental tools.Wherein, use test tube is experiment container, completes the packing to laboratory sample, extraction, washs, hatches and the operation such as container replacing; Use separatory funnel completes the sorting to scientific experiment solution composition.Use funnel to injection experiments solution in more small-bore container, or by adding filter membrane in funnel, complete process such as the filtrations of experimental solutions; Use suction pipe shift experiment solution between the experiment containers such as test tube, reagent bottle, blake bottle, beaker, graduated cylinder, measuring cup, measuring bottle and conical flask; Use pipettor (rotate imbibition and regulate rotating disk, preset liquid absorption, and load onto suction nozzle) quantitative shift experiment solution between the experiment containers such as test tube, reagent bottle, blake bottle, beaker, graduated cylinder, measuring cup, measuring bottle and conical flask.When drawing the experimental solutions of different volumes, as long as change suction nozzle, the experimental solutions of difference in functionality just can be shifted; By syringe and miniature displacer with the use of, the filtration sterilization of a small amount of solution can be realized.Because injector syringe is marked with scale, use syringe also can realize experimental solutions in test tube, reagent bottle, blake bottle, beaker, graduated cylinder, measuring cup, quantitative transfer between measuring bottle and conical flask.
As the test tube of experiment container, volume has plurality of specifications usually.In scientific experiment, these test tubes that laboratory sample is housed often need vertically to be placed in super-clean bench with the spilling of the pollution and experimental system that prevent laboratory sample.For the vertical placement of different size test tube in super-clean bench, the rack for test tube that people place dimension usually on the table top of super-clean bench vertically places these test tubes.
In the scientific experiment operation completed by separatory funnel or funnel, separatory funnel or funnel need vertically to place in super-clean bench.So people are usually on the table top of super-clean bench, place the funnel stand that can be shared by separatory funnel or funnel.For ensureing the stability putting into funnel after-poppet, funnel stand generally has larger base area.
Suction pipe is as the instrument often used in scientific experiment, and a suction pipe is as can be recycled when drawing same solution.As suction pipe horizontal positioned, the table space of the super-clean bench taken is too large.And glass pipette is when horizontal positioned, easily cause the pollution of suction pipe.This will ask for help be that suction pipe prepares the vertical relative assembly placed in super-clean bench.People are usually with the table top of super-clean bench being placed the rack for test tube inserting sterile test tube, and the method vertically inserted by suction pipe in this test tube is to realize the vertical placement of super-clean bench inner suction pipe.
Pipettor is as the instrument quantitatively shifting solution in scientific experiment, and the frequency of use is very high, and the pipettor that a certain suction nozzle is housed sometimes can be recycled when drawing same experimental solutions.The table space of the super-clean bench taken due to pipettor horizontal positioned is too large, and has been drawn through the pipettor of liquid, and the imbibition last time liquid remained in suction nozzle may flow to pipettor and suction nozzle coupling part, causes the pollution to pipettor.This will ask for help be that pipettor prepares the vertical pipettor rack placed in super-clean bench.For ensureing the stability putting into pipettor rack after pipettor, pipettor rack generally has larger base area.
Syringe is as instrument conventional in scientific experiment.In experiment, a syringe, owing to can repeatedly be utilized when shifting same experimental solutions, needs to place in super-clean bench temporarily.The table space of the super-clean bench that syringe can take in the horizontal positioned of super-clean bench table top, also likely because of injector head and other experimental apparatus contact and pollute.
But on the table top of super-clean bench, place the table space taking super-clean bench that the rack for test tube of different size, funnel stand, pipettor rack and syringe can be larger, cause the crowding phenomenon occurring experiment sample, experiment reagent and experiment equipment on super-clean bench table top, these phenomenons can hinder the quick and efficient implementation process of scientific experiment, affect precision and the accuracy rate of scientific experiment.The failure of scientific experiment can be caused time serious.
