Abstract
The utility model discloses a test tube rack, which comprises an upper layer plate, a lower layer plate and four support columns for supporting the upper layer plate and the lower layer plate, wherein holes are formed in the upper layer plate. The beneficial effects or innovations of the utility model are as follows: the test tube rack can be used for simultaneously placing centrifuge tubes with different specifications and arranging the centrifuge tubes with different specifications into a row. In the experiment, samples in centrifuge tubes with different specifications can be arranged according to the serial numbers, so that the experiment efficiency is greatly improved, and the probability of taking wrong samples is reduced.
Description
Technical Field
The utility model relates to a test tube rack.
Background
Centrifuge tubes of various sizes, such as 50ml, 15ml, 2ml and 1.5ml, are currently available in laboratories. During the course of experiments, especially molecular biology, biochemical or cellular experiments, it is often necessary to load 96-well plates with samples, and there is often a need to sample from centrifuge tubes of different sizes. If samples which are stored in centrifuge tubes with different specifications in advance are arranged in a straight line according to the serial numbers, the experimental efficiency is greatly improved, and the probability of taking wrong samples is reduced. However, the test tube rack common in the laboratory at present has the following problems: or only a single specification can be placed, and test tube racks with different specifications are needed to be spliced together, so that the experimental efficiency is affected; or the holes of the test tubes with two specifications are not arranged in the same row, thereby increasing the probability of taking the wrong sample. There is a need for a centrifuge tube rack that can hold centrifuge tubes of different sizes simultaneously and can arrange the centrifuge tubes of different sizes in a row.
Disclosure of Invention
The utility model aims to solve the technical problem of providing the test tube rack capable of simultaneously placing centrifuge tubes with different specifications aiming at the defects of the existing test tube rack.
In order to achieve the aim of the utility model, the test tube rack comprises an upper layer plate, a lower layer plate and four support columns for supporting the upper layer plate and the lower layer plate, wherein holes are formed in the upper layer plate, a hole sleeve made of soft materials is placed in the holes of the upper layer plate, and a cross-shaped notch is formed in the hole sleeve. The test tube rack provided by the utility model can be used for simultaneously placing centrifuge tubes with different specifications, such as 50ml, 15ml, 2ml and 1.5ml centrifuge tubes common to laboratory.
In a preferred embodiment of the utility model, both the upper and lower plates are rigid plastic plates; the support columns are rigid plastic support columns.
In a preferred embodiment of the utility model, the sleeve is supported by soft silica gel or rubber.
In a preferred embodiment of the utility model, the hole is placed in a vertical position within the hole of the upper plate.
In a preferred embodiment of the utility model, holes are also provided in the lower plate, the holes in the lower plate being coaxial with the holes in the upper plate.
In a preferred embodiment of the utility model, 24 holes are provided in the upper plate and 24 holes are also provided in the lower plate.
In a preferred embodiment of the utility model, a plurality of upwardly turned naps are provided on the inner surface of the sleeve.
Due to the adoption of the technical scheme, the beneficial effects or innovations of the utility model are as follows: the test tube rack can be used for simultaneously placing centrifuge tubes with different specifications and arranging the centrifuge tubes with different specifications into a row. In the experiment, samples in centrifuge tubes with different specifications can be arranged according to the serial numbers, so that the experiment efficiency is greatly improved, and the probability of taking wrong samples is reduced.
Drawings
In order to more clearly illustrate the embodiments of the present utility model or the technical solutions in the prior art, the drawings that are required in the embodiments or the description of the prior art will be briefly described, and it is obvious that the drawings described below are only some embodiments of the present utility model, and that other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.
Fig. 1 is a schematic diagram of the overall structure of the utility model.
Detailed Description
The following describes the embodiments of the present utility model further with reference to the drawings and examples. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and are not intended to limit the scope of the present utility model.
As shown in fig. 1, the present utility model is a test tube rack composed of an upper plate 10, a lower plate 20, and four columns 30 supporting the upper plate 10, the lower plate 20. The upper layer plate 10 and the lower layer plate 20 are both hard plastic plates; the support columns 30 are rigid plastic support columns.
24 holes 11 (of course, not limited to 24 holes and the rest of holes) are formed in the upper layer plate 10, a hole sleeve 40 made of soft materials is placed in the holes 11 of the upper layer plate 10, the hole sleeve 40 is supported by soft silica gel or rubber, and the hole sleeve 40 is placed in the holes 11 of the upper layer plate 10 in a vertical state. The sleeve 40 is provided with a cross-shaped notch 41. The test tube rack provided by the utility model can be used for simultaneously placing centrifuge tubes with different specifications, such as 50ml, 15ml, 2ml and 1.5ml centrifuge tubes common to laboratory. Holes are also formed in the lower plate 20, and the holes in the lower plate 20 are coaxial with the holes 11 of the upper plate 10 one by one.
A plurality of upward-turning naps are arranged on the inner surface of the hole sleeve 40, and when the centrifuge tube is inserted into the hole sleeve 40, the upward-turning naps can be turned downwards, so that the centrifuge tube is inserted more tightly and cannot fall out. When the centrifuge tube is pulled out, the fuzz turned downwards can be turned upwards, so that the centrifuge tube is pulled out conveniently.
The samples contained in the centrifuge tubes with different specifications can be arranged in the same line by using 1 or more test tube racks, so that the convenience of sampling is improved, and the probability of taking wrong samples from samples which are not arranged in sequence is reduced.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
