Referring to fig. 3, fig. 3 is a top view of a multifunctional test tube rack provided in an embodiment of the present application. The multi-functional test-tube rack that this application embodiment provided sets up the through-hole of two kinds of specifications on roof 1, constitutes first through-hole group by a plurality of first through-hole 11 promptly to and, the second through-hole group of constituteing by a plurality of second through-hole 12.
The first through hole 11 is a large-sized circular through hole and can be used for placing a test tube with a smaller aperture than the large-sized circular through hole. It should be noted that the large-size circular through hole described in the embodiment of the present application refers to a through hole having a larger aperture than the small-size circular through hole in the second through hole 12, and the small-size circular through hole refers to a through hole having a smaller aperture than the first through hole 11, that is, the large-size circular through hole and the small-size circular through hole described in the embodiment of the present application are relative concepts.

The second through hole 12 can be used not only for placing a conventional test tube, such as a plain test tube, but also for placing a special test tube, such as a multi-well wave plate absorption tube or other special flat reagent tube.
To sum up, the multi-functional test-tube rack that this application embodiment provided through the through-hole that sets up different specifications on roof 1 to satisfy the demand of placing of different specification test tubes in the different experimental procedure, thereby can reduce the operation complexity, improved experiment efficiency.
The distribution positions of the first through hole group and the second through hole group on the top plate 1 are not limited in the embodiment of the present application. Optionally, the first through hole group is distributed in the middle of the top plate 1, and the second through hole group is distributed in the side position of the top plate 1. As shown in FIG. 3, if the top plate 1 is rectangular, the second through holes 12 can be disposed on two sides close to the relatively long side of the top plate 1, wherein the second through holes 12 on any one of the two sides of the relatively long side of the top plate 1 are arranged in a row, so that the test tubes can be placed in the order of the row during the experiment operation.
Further, the first through holes 11 may be distributed in a staggered manner at the middle position of the top plate 1. Since the aperture ratio of the first through holes 11 is large, if the first through holes 11 are arranged in a row in the middle of the top plate 1, the number of the first through holes 11 provided is small. Therefore, in the embodiment of the present application, the first through holes 11 are distributed in a staggered manner at the middle position of the top plate 1, and compared with the manner of arranging in a row, more first through holes 11 can be arranged in the same area, so that the effective area of the top plate 1 is fully utilized.
It should be noted that, in the embodiment of the present application, the number of the first through holes 11 in the first through hole group and the number of the second through holes 12 in the second through hole group are not limited, and may be appropriately set according to the size of the top plate 1.
Further, the second through-hole groups may be divided into a plurality of sub-through-hole groups, wherein a distance between two adjacent sub-through-hole groups is larger than a distance between two adjacent second through-holes 12 in each sub-through-hole group. In a specific example, as shown in fig. 3, the second through-hole group includes 4 sub-through-hole groups, which are a sub-through-hole group i, a sub-through-hole group ii, a sub-through-hole group iii, and a sub-through-hole group iv, and the second through-holes 12 belonging to the same sub-through-hole group can be clearly distinguished according to the distance between each second through-hole 12. Therefore, the embodiment of the application is suitable for a relatively complex experiment, such as an experiment with a plurality of comparative examples, by dividing the second through hole group into a plurality of sub-through hole groups, wherein a sample in the same comparative example can be placed in the same sub-through hole group separately, so that the samples in different comparative examples are prevented from being mixed together and being indistinguishable during the experiment process, and the experiment efficiency is prevented from being affected.
In the embodiment of the present application, the number of the second through holes 12 in each sub-through hole group is not limited, and the number of the second through holes 12 in each sub-through hole group may be the same or different. For example, each sub-via group includes eight second vias 12, and for example, each of sub-via group i and sub-via group iv includes eight second vias 12, and each of sub-via group ii and sub-via group iii includes ten second vias 12.
None of the prior art test tube racks has position markers, so that when pipetting or dispensing reagents, omission or repetition of operations often occurs. Based on this, in order to prevent omission or repeated operation during the experiment, in the embodiment of the present application, a first mark for marking each sub-through hole group in the second through hole group is printed on the top plate 1. And printing a first mark near each sub-through hole group to distinguish different sub-through hole groups, wherein the first mark can be Arabic numerals, Roman numerals, English letters and the like, and the first mark is not limited in the application. For example, in the second via group, i, ii, iii, iv … … are sequentially marked in the vicinity of the corresponding sub-via group in a predetermined order. Particularly, in a comparative experiment, the first mark is particularly important, and each proportion can be obviously distinguished, so that the experiment efficiency is improved.
Further, a second mark may be printed at a position corresponding to each second through hole 12 of each through hole group to distinguish each second through hole 12 of each through hole group, where the second mark may be an arabic numeral, a roman numeral, an english letter, or the like, and the application is not limited thereto. For example, in each sub-through hole group, 1, 2, 3, 4, 5, 6, 7, 8 … … are sequentially marked near the corresponding second through hole 12 in the order from left to right, so as to distinguish the second through holes 12 in each sub-through hole group, so that in the experiment, the test tubes can be conveniently placed in the corresponding second through holes 12 according to the experimental characteristics, thereby avoiding the problems of omission or repeated operation.
Similarly, in the embodiment of the present application, the top plate 1 is also printed with a third mark, and the third mark is used for marking each first through hole 11 in the first through hole group. Similarly, the third mark may be an arabic numeral, a roman numeral, an english alphabet, or the like, which is not limited in the present application. For example, in the first through-hole group, 1, 2, 3, 4, 5, 6, 7, 8 … … are sequentially marked near the corresponding first through-holes 11 in order from left to right, thereby distinguishing the first through-holes 11 in the first through-hole group. Further, in order to distinguish the first through hole group from the second through hole group, the third mark is preferably marked differently from the first mark, for example, if the first mark is an arabic numeral, the third mark may be marked in an english alphabet, and specifically, A, B, C, D, E, F, G, E … … may be marked in the first through hole group in order from left to right in the vicinity of the corresponding first through hole 11.
The embodiment of the application provides a pair of multi-functional test-tube rack through set up the through-hole of different specifications on roof 1 to satisfy the demand of placing of different specification test tubes in different experimental steps, thereby can reduce the operation complexity, improved experiment efficiency. Further, by printing the first mark on the top plate, the sub-through-holes in the second through-hole group can be distinguished, the second mark can be printed on the top plate, the second through-holes 12 in each sub-through-hole group can be distinguished, the third mark can be printed on the top plate, the first through-holes 11 in the first through-hole group can be distinguished, and omission or repetition of operations during transfer of liquid or placement of reagents can be avoided.
