The purpose of this utility model is that a kind of student experimenting titration outfit is proposed, to solve proposed in background technique
The problem of.
In order to achieve the above objectives, the utility model provides the following technical solutions: including pedestal, collecting tank, support rod, several
A fixed device, blank, rotating electric machine and rack for test tube；The susceptor surface is equipped with plurality of through holes；The collecting tank is separable
Ground is set to the base end face；The support rod is set to the base top surface；Each described fixed device one end is removably
It put on the supporting rod, the fixed device other end is respectively fixed with butterfly clamp and magnifying glass；The blank is set to described
Base top surface；The rotating electric machine is set to the base top surface, and the rotating electric machine motor shaft is equipped with test tube collet, the rotation
Rotating motor shell is equipped with controller, and the rotating electric machine connects and is controlled by the controller；The rack for test tube is set to described white
On plate.
Preferably, the fixed device is cross clamp.
Preferably, the collecting tank is polytetrafluoroethylene (PTFE) collecting tank.
Preferably, the rotating electric machine is powered by external power supply.
Preferably, the controller is singlechip controller.
By the above-mentioned description to the utility model structure it is found that compared to the prior art, the utility model has following excellent
Point:
A kind of student experimenting titration outfit provided by the utility model replaces operator to shake examination using rotating electric machine
Pipe, can reduce the burden of operator；The susceptor surface is equipped with several through-holes, and bottom end is equipped with collecting tank, can collect drop
The reagent fallen prevents from causing danger to experimental bench, user；It can be referred to by blank and magnifying glass cooperation convenient for operator's observation
Show the discoloration of agent to more accurately judge titration end-point.
Detailed description of the invention
The attached drawing constituted part of this application is used to provide a further understanding of the present invention, the utility model
Illustrative embodiments and their description are not constituteed improper limits to the present invention for explaining the utility model.In attached drawing
In:
Fig. 1 is the utility model positive structure diagram；
In figure: 1 pedestal, 2 collecting tanks, 3 support rods, 4 fixed devices, 41 butterfly clamps, 42 magnifying glasses, 5 blanks, 6 electric rotatings
Machine, 61 test tube collets, 62 controllers, 7 rack for test tubes.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment
With reference to Fig. 1, a kind of student experimenting titration outfit, including pedestal 1, polytetrafluoroethylene (PTFE) collecting tank 2, support rod 3,2
A cross clamp 4, blank 5, rotating electric machine 6 and rack for test tube 7；1 surface of pedestal is equipped with plurality of through holes 11；The polytetrafluoroethyl-ne
Alkene collecting tank 2 is separably set to 1 bottom surface of pedestal；The support rod 3 is set to 1 top surface of pedestal；Each cross
It presss from both sides 4 one end to be detachably arranged on the support rod 3, fixed 4 other end of device is respectively fixed with butterfly clamp 41 and puts
Big mirror 42；The blank 5 is set to 1 top surface of pedestal；The rotating electric machine 6 is set to 1 top surface of pedestal, the rotating electric machine
6 are powered by external power supply, and 6 motor shaft of rotating electric machine is equipped with test tube collet 61, and 6 shell of rotating electric machine is equipped with monolithic
Machine controller 62, the rotating electric machine 6 connect and are controlled by the singlechip controller 62；The rack for test tube 7 is set to described white
On plate 5.
Utility model works principle: when carrying out titration experiments, the test tube of the reagent to be titrated containing indicator is put into examination
In pipe clamp set 61, buret is clamped using butterfly clamp 41, the position of adjustment cross clamp 4 makes buret and magnifying glass 42 be in same
On vertical direction；When carrying out titration operation, rotating electric machine 6 is started by singlechip controller 62, titrating solution instills examination to be titrated
