Description

Technical Field

[0001] The utility model belongs to the technical field of centrifuge tube rack manufacturing, in particular to a multi-aperture centrifuge tube rack. Background Art

[0002] In the field of biotechnology, it is often necessary to process samples such as blood and tissues, and centrifuge tubes are needed to preserve the samples. Centrifuge tube racks provide a convenient way to store samples. Various centrifuge tubes can be placed neatly and orderly according to different specifications and needs, which is convenient for sample identification, tracking and management; in cell biology research, centrifuge tube racks are often used in cell culture and sorting experiments. Cell culture media and cell suspensions need to be processed in centrifuge tubes, and centrifuge tube racks provide stable support for these operations. Centrifuge tube racks have a wide range of applications in the field of biology, providing experimental personnel with convenient support for sample storage, processing, separation and culture operations, and promoting the progress of biological research.

[0003] During the experimental operation, it is often necessary to handle centrifuge tubes of different specifications at the same time. However, the existing centrifuge tube racks have fixed apertures and poor compatibility. Centrifuge tube racks with a single aperture can only be used for centrifuge tubes of specific specifications. They have poor compatibility with centrifuge tubes of different specifications and cannot meet the diverse experimental needs. In a biosafety cabinet, due to its high requirements for sterility and biosafety, the experimental operation space is limited. Traditional centrifuge tube racks may take up a large space due to size issues. Utility Model Content

[0041] like Figure 1-4 As shown, a multi-aperture centrifuge tube rack comprises a bottom plate 1, a left plate 11 and a right plate 12 are fixedly connected to both sides of the bottom plate 1, and the left plate 11 and the right plate 12 are arranged perpendicular to the bottom plate 1;

[0042] A first orifice plate 2 and a second orifice plate 3 are disposed between the left plate 11 and the right plate 12, wherein the first orifice plate 2 is disposed above the second orifice plate 3. By disposing the first orifice plate 2 and the second orifice plate 3, the stability of the centrifuge tube placed in the centrifuge tube rack can be ensured. The two orifice plates fix the centrifuge tube, and the centrifuge tube is not easy to shake.

[0043] The first orifice plate 2 and the second orifice plate 3 are both provided with a first plug hole 4 and a second plug hole 5, and the first plug hole 4 and the second plug hole 5 on the first orifice plate 2 are completely consistent in aperture and arrangement with the first plug hole 4 and the second plug hole 5 on the second orifice plate 3;

[0044] The first jacks 4 and the second jacks 5 are provided in two rows respectively;

[0045] The first plug hole 4 is used to place a centrifuge tube with a capacity of 50 ml, and the second plug hole 5 is used to place a centrifuge tube with a capacity of 15 ml, because in the experiment, the 50 ml and 15 ml centrifuge tubes are used more frequently and are more practical;

[0046] One row of second jacks 5 is arranged in the gap between the two rows of first jacks 4, and the other row of second jacks 5 is arranged on the other side of one row of first jacks 4. The first jacks 4 and the second jacks 5 are arranged alternately, which can reduce the gap between the apertures of the first orifice plate 2 and the second orifice plate 3 and improve the area utilization rate;

[0047] A folding plate 6 is provided on the side of the left side plate 11 away from the first orifice plate 2 through a right-angle hinge 61. A third plug hole 62 for placing an EP tube is provided on the folding plate 6. The third plug hole 62 is provided in two rows. The EP tube is a micro-capacity EP tube, which can be 1.5 ml, 2 ml, or 5 ml. When the centrifuge tube rack is not in use, the folding plate 6 is folded up. When the third plug hole 62 is needed to place the EP tube, the folding plate 6 can be opened to be perpendicular to the left side plate 11. The folding plate 6 is provided on the centrifuge tube rack. When a micro-capacity EP tube is needed, there is no need to re-place a new tube rack, which can better improve the experimental efficiency and save space.

[0048] The right side plate 12 is penetrated with two circular holes 7. When taking the centrifuge tube rack, fingers can be placed in the two circular holes 7 to avoid the centrifuge tube rack being too slippery and unstable when taking it, so that it can be taken and placed more steadily.

[0049] The front and rear sides of the bottom plate 1 are provided with a front side plate 13 and a rear side plate 14, and the front side plate 13 and / or the rear side plate 14 can be rotated and opened relative to the bottom plate 1. After the centrifuge tube rack is used, the front side plate 13 and / or the rear side plate 14 can be rotated and opened to clean the bottom plate 1, the first orifice plate 2, and the second orifice plate 3;

[0050] The front side plate 13 and / or the rear side plate 14 can be rotatably mounted on the bottom plate 1 via a rotating shaft, or can be mounted on the bottom plate 1 via hinges.

[0051] A groove 15 is formed on one side of the left side plate 11 away from the first orifice plate 2 . The size of the groove 15 is consistent with that of the folding plate 6 . When the folding plate 6 is folded, it is engaged in the groove 15 , making the centrifuge tube rack more beautiful as a whole.

[0052] A handle 63 is provided on the side of the folding plate 6 away from the left side plate 11 to facilitate the folding plate 6 to be rotated, opened or closed.

[0053] The bottom plate 1 is provided with a silicone cushion 8, which can provide good buffering and protection for the centrifuge tubes because most centrifuge tubes are made of glass, so as to prevent the operator from using improper force when placing the centrifuge tube, causing the bottom of the centrifuge tube to impact with the bottom plate 1, causing the centrifuge tube to break and causing experimental contamination.

[0054] The bottom plate 1, the left plate 11, the right plate 12, the front plate 13, the rear plate 14, the first orifice plate 2, the second orifice plate 3 and the folding plate 6 are made of high-strength plastic or acrylic, because high-strength plastic or acrylic is not easy to deform, and the material has good stability and is not easily corroded, and is easy to clean, thereby increasing the practical life of the centrifuge tube rack.

[0055] The working principle of the utility model is as follows: during the experimental operation, the centrifuge tube rack is placed on the workbench, and the 50ml and 15ml centrifuge tubes containing samples are placed in the first jack 4 and the second jack 5 respectively. Because the first orifice plate 2 and the second orifice plate 3 are arranged up and down, and the aperture arrangement is completely consistent, the stability of the placement of the centrifuge tube can be guaranteed, and there will be no shaking. A silicone cushion 8 is laid on the bottom plate 1, which has a good buffering and protection for the bottom of the centrifuge tube, avoiding the operator from using improper force when placing the centrifuge tube, resulting in the impact force between the bottom of the centrifuge tube and the bottom plate 1, causing the centrifuge tube to break, causing experimental contamination. If an EP tube is needed to take a trace amount of the sample during the work process, pull the handle 63 to drive the folding plate 6 to rotate to be perpendicular to the left plate 11, and put the EP tube into the third jack 62. When the centrifuge tube rack is full or the experiment is completed and needs to be placed elsewhere, put your fingers into the two circular holes 7 on the right wall 12 to ensure that the centrifuge tube rack is stable and will not slip during the movement.

[0056] After using the centrifuge tube rack, the front side plate 63 or the rear side plate 64 is rotated, and the centrifuge tube rack is opened to clean the bottom plate 1, the first orifice plate 2, and the second orifice plate 3 to avoid sample contamination during next use.

[0057] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
