Abstract
Description
Technical Field
[0001] This utility model belongs to the field of experimental equipment technology, specifically relating to a shared centrifuge tube rack. Background Technology
[0002] Centrifuge tube racks are commonly used consumables in laboratories, used to fix and organize centrifuge tubes to facilitate centrifugation operations. They are an indispensable tool in laboratory centrifugation operations, and proper selection and use can improve experimental efficiency and safety.
[0003] However, the centrifuge tube racks currently in use have the following problems:
[0004] 1. During the experiment, due to the large number of samples being tested, and the dilution factors of different samples ranging from tens to tens of thousands or even millions of times, handling different samples on the same dilution centrifuge tube rack can easily cause confusion and cross-contamination between samples. The main reason is that the gaps between the holes in the centrifuge tube rack are very small, and the caps of adjacent centrifuge tubes often come into contact, which often leads to difficulties in retrieving centrifuge tubes and sample contamination during the process of adding and removing samples.
[0005] Second, in cases with multiple gradients and multiple samples, marking the dilution factor on the tube caps is a complex and confusing operation that can easily lead to errors in the experimenter's operation, resulting in experimental failure and invalid data. Utility Model Content
[0006] This invention provides a shared centrifuge tube rack. Firstly, the centrifuge tube rack can minimize cross-contamination between holes. Secondly, by setting markings on the centrifuge tube rack, test tubes with different dilution ratios can be placed in the same area, thereby reducing operational errors by the experimenter.

[0013] Preferably, the number of lifting brackets is four, and the four lifting brackets are respectively located at the four corner edges of the first plate and the four corner edges of the second plate.
[0014] Preferably, each of the lifting brackets includes a fixed frame and a telescopic frame. The fixed frame is detachably mounted on the second plate in the vertical direction, and the telescopic frame is detachably mounted on the first plate in the vertical direction. The fixed frame has a slot that extends in the vertical direction, and the telescopic frame is inserted into the slot. The fixed frame is also equipped with a limiting mechanism to limit the movement distance of the telescopic frame in the slot, thereby limiting the distance between the first plate and the second plate in the vertical direction.
[0015] Preferably, the limiting mechanism includes multiple limiting holes and a limiting pin, the multiple limiting holes are sequentially opened on the fixed frame in a vertical direction, and the telescopic frame is provided with a positioning hole;
[0016] When the limiting pin is inserted into one of the limiting holes and the positioning hole, the telescopic frame is fixed in the slot in the fixed frame to achieve the fixation of the telescopic frame after it is raised and lowered relative to the fixed frame.
[0017] Preferably, a first through hole is provided at each of the four corner edges of the first plate, and a second through hole corresponding to the first through hole is provided at each of the four corner edges of the second plate.

[0019] Preferably, the first plate has several rows of second centrifuge tube placement holes along its width, and each row of second centrifuge tube placement holes is located between each two adjacent rows of first centrifuge tube placement holes.

[0022] The beneficial effects of the utility model are:
[0023] (1) This utility model adopts two plates and a lifting bracket. The lifting bracket is arranged in a vertical direction and its two ends are connected to the two plates, so that the two plates can be raised and lowered in a vertical direction with the assistance of the lifting bracket. The two plates are arranged in parallel. Each plate has a length direction and a width direction.

The first plate has a first centrifuge tube placement hole along the length direction and a multi-row first centrifuge tube placement hole along the width direction. The second plate has a first centrifuge tube placement position vertically corresponding to the first centrifuge tube placement hole. The purpose is to enable the centrifuge tube rack to have the advantage of being suitable for placing centrifuge tubes of various specifications.

Detailed Implementation
[0032] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0033] like Figure 1-5 As shown, it includes two plates and a lifting bracket 2. The lifting bracket 2 is set in a vertical direction and its two ends are connected to the two plates, so that the two plates can be raised and lowered in a vertical direction with the assistance of the lifting bracket 2.
[0034] Two plates are arranged in parallel; each plate has a length direction and a width direction; the plate connected to the top of the lifting bracket 2 is the first plate 1, and the other plate is the second plate 3. The first plate 1 has a first centrifuge tube placement hole 4 along the length direction and multiple rows of first centrifuge tube placement holes 4 along the width direction. The second plate 3 has a first centrifuge tube placement position that is vertically corresponding to the first centrifuge tube placement hole 4.
[0035] The edge of the first plate 1 has a number of first marks along the width direction, and the edge of the first plate 1 has a number of second marks along the length direction;
[0036] Furthermore, each first centrifuge tube placement hole 4 corresponds to several second marks; and each row of first centrifuge tube placement holes 4 corresponds to a first mark.
[0037] The first centrifuge tube 6 is placed in the first centrifuge tube placement hole 4. The first centrifuge tube 6 has a flip-top tube cap 7. After the two flip-top tube caps 7 are opened and laid horizontally with the first centrifuge tube 6, there is a first gap between them.
[0038] There are four lifting brackets 2, and the four lifting brackets 2 are respectively located at the four corner edges of the first plate 1 and the four corner edges of the second plate 3.
[0039] Each lifting bracket 2 includes a fixed frame 21 and a telescopic frame 22. The fixed frame 21 is detachably mounted on the second plate 3 in the vertical direction, and the telescopic frame 22 is detachably mounted on the first plate 1 in the vertical direction. The fixed frame 21 has a slot that extends in the vertical direction, and the telescopic frame 22 is inserted into the slot. The fixed frame 21 is also equipped with a limiting mechanism to limit the distance the telescopic frame 22 moves in the slot, thereby limiting the distance between the first plate 1 and the second plate 3 in the vertical direction.
[0040] The limiting mechanism 8 includes multiple limiting holes 81 and a limiting pin 82. The multiple limiting holes 81 are sequentially opened on the fixed frame 21 in a vertical direction, and the telescopic frame 22 is provided with a positioning hole 9.
[0041] When the limiting pin 82 is inserted into one of the limiting holes 81 and the positioning hole 9, the telescopic frame 22 is fixed in the slot in the fixed frame 21 to achieve the fixation of the telescopic frame 22 after it is raised and lowered relative to the fixed frame 21.
[0042] The first plate 1 has a first through hole at each of its four corner edges, and the second plate 3 has a second through hole at each of its four corner edges corresponding to the first through hole.
[0043] The telescopic frame 22 includes a telescopic frame plug 221 and a telescopic frame insertion part 222. The telescopic frame insertion part 222 is inserted into the first through hole, and the telescopic frame plug 221 is plugged on the first plate 1. The fixed frame 21 includes a fixed frame plug 211 and a fixed frame insertion part 212. The fixed frame insertion part 212 is inserted into the second through hole, and the fixed frame plug 211 is plugged on the second plate 3.
[0044] The first plate 1 has several rows of second centrifuge tube placement holes 5 along its width, and each row of second centrifuge tube placement holes 5 is located between each two adjacent rows of first centrifuge tube placement holes 4. The second plate 3 has a second centrifuge tube placement position that is vertically corresponding to the second centrifuge tube placement hole 5.
[0045] The second centrifuge tube placement hole 5 has a larger diameter than the first centrifuge tube placement hole 4.
[0046] The number of second centrifuge tube placement holes 5 in each row is several. A second centrifuge tube 10 is placed in each second centrifuge tube placement hole 5. A tube cap 11 is screwed onto the second centrifuge tube 10. There is a second gap between each two adjacent rows of tube caps 11 and between each two adjacent tube caps 11 in each row.
[0047] The first plate 1 is marked with different data on both sides along the width direction, and the data marked on each side is a power of 10 of the concentration data, where N is a positive integer and greater than or equal to 0; the first plate is also marked with different data on both sides along the length direction, and the data marked on each side is a power of 10 of the concentration data, where N is a positive integer and greater than or equal to 0.
[0048] The data marked on the first plate 1 are different in the width direction and the length direction.
[0049] The purpose of the above scheme is to mark data on the first plate 1, such as concentration marking, capacity marking, etc., and to mark it according to the actual use, such as dilution by 1, 10, 100, 1000, 10000, etc., so as to facilitate placement and easy retrieval.
[0050] This utility model is implemented in the following manner:
[0051] First, when the limiting pin is inserted into the corresponding limiting hole 81 and positioning hole, the distance between the first plate 1 and the second plate 3 is matched to the placement of the first centrifuge tube 6. Then, after the first centrifuge tube 6 is inserted into the first centrifuge tube placement hole 4, it is placed according to the markings on the first plate 1.
[0052] Furthermore, when the flip-top tube cap 7 is opened until it is parallel to the horizontal direction of the opening of the first centrifuge tube 6, there is a first gap between the two flip-top tube caps 7 after they are opened and laid horizontally with the first centrifuge tube 6. Therefore, the two adjacent flip-top tube caps 7 do not come into contact, and there is no risk of contamination.
[0053] When the second centrifuge tube 10 needs to be inserted, firstly, all the first centrifuge tubes 6 are removed (that is, when the second centrifuge tube 10 is inserted into the centrifuge tube rack, the first centrifuge tube 6 is not placed on the centrifuge tube rack, and similarly, when the first centrifuge tube 6 is inserted, the second centrifuge tube 10 is not placed). Then, the limiting pin 82 is inserted into the corresponding limiting hole 81 and positioning hole 9, so that the distance between the first plate 1 and the second plate 3 matches the insertion of the second centrifuge tube 6 (the best way is to make the second centrifuge tube contact the second centrifuge tube placement position on the second plate 3, for example, contact the bottom of the second centrifuge tube placement slot). Since there is a second gap between each two adjacent rows of tube caps 11 and between each two adjacent tube caps 11 in each row, there is no contact between each two adjacent rows of tube caps 11 and between each two adjacent tube caps 11 in each row, so there is no risk of contamination.
[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
