Abstract

The utility model relates to a multi-purpose test tube rack which is characterized by comprising a test tube rack structure formed by an outer frame, an upper-layer net rack, a middle-layer net rack and a lower-layer net rack, wherein at least one side of the test tube rack structure is provided with a supporting leg mechanism for adjusting an inclination angle when the test tube rack is slantways placed. In the multi-purpose test tube rack provided by the utility model, the test tubes can be fixed on the test tube rack by utilizing a three-layer net rack structure; the supporting leg mechanism formed by fixing nuts and adjustable supporting leg screws is used for adjusting the inclination angle of the test tube rack when the test tube rack is slantways placed, and the test tube rack is adjusted to a proper angle, which can meet the requirements of manufacture and oblique culture of a slant culture medium; a sufficient space is remained between a lower ring frame of the outer frame and the lower-layer net rack, so that the test tube rack can be superposed during upright culture or storage, which saves the space; and meanwhile, because the stress is on the outer frame, the condition that test tubes are pressed can be avoided, so that the multi-layer superposition of the test tube rack can be realized, which saves the space.

Description

The multipurpose rack for test tube

Technical field

The utility model relates to instrument and the device of using in the Microbiological Lab, specifically, relates to rack for test tube.

Background technology

At present, the common methods of making slant medium in the Microbiological Lab is that test tube is tilting on the fixture of certain altitude, makes that culture medium forms certain inclined-plane in the test tube.The disclosed certain methods of prior art is that test tube is fixed on single fixedly rack for test tube or the adjustable rack for test tube; Perhaps utilize two baffle plates of the movable hinge of band to cooperate restraining to make.Above-mentioned preceding two kinds of methods are more suitable for a small amount of preparation, but will waste time and energy when making when needs are in enormous quantities, and cultivate or deposit when using as test tube, and it is bigger to take the place, can't superpose; A kind of method in back has solved the problem of making in enormous quantities, but complex structure, during operating cost, the test tube that needs earlier branch to be installed culture medium fixes sterilization with other device, and then test tube is fixed thereon, and only can be used to make the slant medium use, can't be used for cultivating or stacking.

Summary of the invention

The purpose of this utility model is to provide a kind of multipurpose rack for test tube, can be used for making slant medium, the multipurpose rack for test tube of also can be used for the inclination of test tube, vertically cultivating and deposit.

The purpose of this utility model is achieved in that a kind of multipurpose rack for test tube, it is characterized in that: comprise the rack for test tube structure of forming by outside framework, upper strata rack, middle level rack, lower floor's rack, regulate the support leg mechanism at angle of inclination when at least one side of this rack for test tube structure is provided with for the inclination placement.

Described support leg mechanism is to have at least two groups to be arranged on the nut of described rack for test tube texture edge and the adjustable feet screw that cooperates with nut.

Described upper strata rack is consistent with the aperture of middle level rack and can allow test tube pass through, and lower floor rack aperture is used to support test tube less than test tube diameter 1/2.

Distance between rack bottom, described upper strata and lower floor rack top is 3/4ths of a test tube length.

Described outside framework has ring frame down, leaves the space that stacks setting for rack for test tube between this time ring frame and the lower floor's rack.

The multipurpose rack for test tube that the utility model provides utilizes the triple layer grid structure test tube can be fixed on the rack for test tube; The finger support leg mechanism that hold-down nut and adjustable leg screw are formed is used for regulating its angle of inclination when rack for test tube tilts to place, and rack for test tube is adjusted to proper angle, can satisfy the making and the inclination culture requirement of slant medium; Outside framework down leaves enough spaces between ring frame and the lower floor's rack, makes when vertically cultivating or depositing the rack for test tube conserve space that can superpose, because stressed on outside framework, can avoid pushing test tube simultaneously, stacks the saving space so can realize the multilayer of rack for test tube.The utility model can effectively solve present slant medium make complicated, time-consuming, bigger problem takes up room, simultaneously can make inclined-plane making, inclined-plane again or vertically cultivate and deposit all can solve, save the laboratory expense and also saved the space with a rack for test tube.

Description of drawings

Fig. 1 is the schematic perspective view of the multipurpose rack for test tube that provides of embodiment.

Fig. 2 is the right sectional drawing when tilting behind the multipurpose rack for test tube installing test tube that provides of embodiment.

Fig. 3 is a plurality of multipurpose rack for test tubes that embodiment provides right sectional drawings when vertically stacking.

The specific embodiment

As shown in Figure 1, the multipurpose rack for test tube that present embodiment provides comprises outside framework 1, upper strata rack 2, middle level rack 3, lower floor's rack 4, nut 5 and leg screw 6, outside framework 1 is as main backstop, upper strata rack 2, middle level rack 3, lower floor's rack 4 from top to bottom hierarchically are arranged on the outside framework 1, thereby form whole rack for test tube structure.Described upper strata rack is consistent with the aperture of middle level rack and can allow test tube pass through, and lower floor rack aperture is used to support test tube less than test tube diameter 1/2.Distance between rack bottom, upper strata and lower floor rack top is 3/4ths of a test tube length.Two nuts 5 are fixedly installed on the left surface of rack for test tube structure, particularly, two nuts 5 are separately positioned on rack for test tube structure left surface, and between upper strata rack 2 and middle level rack 3, two leg screws 6 cooperate with two nut 5 adjustable grounds respectively, the support leg mechanism when two groups of nuts 5 and leg screw 6 are configured for rack for test tube and are obliquely installed.Outside framework 1 has ring frame down, leaves the space that stacks setting for rack for test tube between this time ring frame and the lower floor's rack 4.

The using method and the process of the multipurpose rack for test tube that the foregoing description provides are as follows: during in conjunction with preparation shown in Figure 2 inclined-plane, test tube is inserted in the rack for test tube, the packing culture medium, sterilization, when treating that culture medium does not solidify, the outside framework 1 of slowly mentioning nut 5 opposite sides, retention nut 5 contacts with desktop the body side frame bottom in the same way simultaneously, whole rack for test tube and test tube are wherein tilted, according to general slant medium preparation requirement, adding culture medium is test tube volume 1/5 to 1/4, and chamfer length is a test tube length 1/2 to 2/3, so test tube and horizontal plane angle are 10 to get final product about spending, adjust adjustment screw 6, make that medium slant is in correct position in the test tube.Same the method when the inclined-plane is cultivated.

In addition, when needs are vertically cultivated or deposited, can reach the effect of saving the space like this, bear by the rack for test tube outside framework because of weight simultaneously, avoid test tube to be squeezed by the stack of carrying out a plurality of rack for test tubes shown in Figure 3.
