Description

The centrifuge that can use for the test tube of different tube diameters

Technical field

The utility model relates to a kind of chemical experiment device, relates in particular to the centrifuge that a kind of test tube for different tube diameters uses.

Background technology

In the process of biological and chemical experiment, often need allow invisible spectro material produce sedimentation and isolate solid and liquid by centrifuge.Yet, the rack for test tube that the tradition centrifuge is provided only can be installed the test tube of identical caliber, if when running into the caliber of test tube situation inequality, different centrifuges must be changed or different rack for test tubes is operated in batches, not only expend experimental period, also will prepare simultaneously the rack for test tube even the centrifuge of multiple different size, the demand with in response to the test tube of different tube diameters so then can cause experimental cost to improve.

The utility model purpose

Main purpose of the present utility model is to provide a kind of centrifuge that uses for the test tube of different tube diameters, and it can carry out centrifugal action to the test tube of different tube diameters, to save experimental period and to reduce experimental cost.

For reaching above-mentioned purpose, the centrifuge that the test tube of Gong the different tube diameters that the utility model provides uses includes,

One base;

One motor is located at described base; And

One rack for test tube connects described motor, can be driven by it and rotates, and the perforation in a plurality of different apertures is arranged.

The above-mentioned aperture of stating perforation is to the inboard descending arrangement of rack for test tube from the outside of described rack for test tube.

Above-mentioned rack for test tube has a junction and both wing portions, and connecting portion connects motor, and both wing portions is extended by the two opposite sides of connecting portion with being inclined upwardly, and has the perforation of a plurality of different pore sizes respectively.

As this another novel scheme, centrifuge also comprises a loam cake and a microswitch, and this loam cake is on described base, and has a pressure section, microswitch is located on the described base, and is electrically connected with described motor, starter when replaced by the pressure section of loam cake.

The centrifuge that the utility model provides, rack for test tube has the perforation of a plurality of different pore sizes, use for the test tube of most root different tube diameters and install, allow the test tube of different tube diameters can be simultaneously or carry out centrifugal action and the rack for test tube that do not need more to renew in batches, to reach this novel purpose, very easy to use.

Below in conjunction with accompanying drawing the most preferred technical scheme of the utility model is described in further detail.

Description of drawings

Fig. 1 is the cutaway view of the utility model preferred embodiment.

The stereogram of the rack for test tube that Fig. 2 is provided for the utility model preferred embodiment.

The vertical view of the rack for test tube that Fig. 3 is provided for the utility model preferred embodiment.

Among the figure, the 10-centrifuge; The 12-test tube; The 20-base; The 22-accommodation space; The 30-loam cake; The 32-pressure section; The 40-motor; The 50-rack for test tube; The 52-connecting portion; The 54-alar part; The 56-perforation; The 60-microswitch.

The specific embodiment

In order to understand preferred version of the present utility model, make those skilled in the art can realize the utility model, see also Fig. 1 to Fig. 3.

Referring to Fig. 1, be the centrifuge 10 of the utility model preferred embodiment, include a base 20, a loam cake 30, a motor 40, a rack for test tube 50, and a microswitch 60.Base 20 inside have an accommodation space 22.Loam cake 30 is located on the base 20 and is positioned at the top of base 20, and has the pressure section 32 of a downward projection.Motor 40 is fixed in base 20 and is positioned at accommodation space 22, in order to as power resources.

Referring to Fig. 2, Fig. 3, rack for test tube 50 has a junction 52 and two alar parts 54, wherein, the connecting portion 52 of rack for test tube 50 is connected with motor 50, make rack for test tube 50 between base 20 and loam cake 30, and can be subjected to the driving of motor 30 and rotate, this two alar part 54 is extended by the two opposite sides of connecting portion 52 with being inclined upwardly, and has the perforation 56 of a plurality of different pore sizes respectively, these perforation apertures of 56 are inboard and present descending arrangement mode to the alar part 54 of rack for test tube 50 from alar part 54 outsides of rack for test tube 50, that is the big more perforation 56 in aperture is the closer to alar part 54 outsides of rack for

test tube

50,56 alar part 54 inboards the closer to rack for test tube 50 of perforation that the aperture is more little.

Microswitch 60 is fixed on the base 20 and is positioned at accommodation space 22, and is electrically connected with motor 40, can be subjected to the replacing and starter 30 of pressure section 32 of loam cake 30 when loam cake 30 is covered on base 20.

It more than is the detailed structure of this novel centrifugal machine 10, when using this novel centrifuge 10, at first loam cake 30 is opened, then insert in the suitable perforation 56 according to the big young pathbreaker's test tube 12 of caliber of test tube 12 again, after treating that test tube 12 storings finish, just loam cake 30 can be covered on base 20, at this moment, the pressure section 32 of loam cake 30 can touch microswitch 60, microswitch 60 will send a signal immediately with starter 40, and rack for test tube 50 can be subjected to the driving of motor 40 and by self rotation test tube 12 be produced centrifugal actions.When experiment finishes, as long as open loam cake 30, make the pressure section 32 of loam cake 30 leave microswitch 60, motor 40 will shut down and allow rack for test tube 50 stop operating gradually, after rack for test tube 50 stops operating fully, test tube 12 can be taken out.

Therefore, this novel centrifuge 10 can allow the test tube 12 of different tube diameters reach the effect of Separation of Solid and Liquid simultaneously, does not need to change the different rack for test tube of specification, and then reaches the purpose of saving experimental period and reducing experimental cost.

This novel in the foregoing description disclosed constituent components, only for illustrating, be not the scope that is used for limiting this case, substituting or variation of other equivalent elements also should be among the patent protection scope of this case.
