Description

Technical Field

[0001] The utility model relates to the technical field of experimental instruments, in particular to a centrifuge tube rack. Background Art

[0002] Microcentrifuge tubes, also known as EP tubes, are a type of small centrifuge tube. They are commonly used for processing microsamples in molecular biology, biochemistry, and medical laboratories. They are typically used in conjunction with microcentrifuges to separate trace reagents. Common microcentrifuge tube capacities include 0.2ml, 0.5ml, 1.5ml, 2.0ml, and 5.0ml, making them suitable for processing microsamples.

[0003] A microcentrifuge tube rack is a device specifically designed to store and organize microcentrifuge tubes. Its main function is to provide a stable support platform, allowing microcentrifuge tubes to remain in a vertical or horizontal position during the experiment, thereby facilitating sample access and storage.

[0004] Multifunctional microcentrifuge tube racks are flexible and adaptable laboratory equipment used to store and organize microcentrifuge tubes and cryotubes of varying sizes and capacities. Compared to standard microcentrifuge tube racks, multifunctional microcentrifuge tube racks typically feature more wells and a wider range of applicability, meeting diverse experimental needs and accommodating a wide range of microcentrifuge tube and cryotube sizes available on the market.

[0005] However, existing multifunctional microcentrifuge tube racks made of injection molding are relatively light overall, with a hole in the middle for accommodating centrifuge tubes. Compared to the ends of the rack, the middle material is thin and easily deformed, making it difficult to place stably on a laboratory bench. In addition, existing multifunctional microcentrifuge tube racks can only be compatible with one or two products. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a centrifuge tube rack, which ensures that the centrifuge tube rack can be stably placed on a laboratory table and is suitable for centrifuge tubes and cryopreservation tubes of various specifications.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] A centrifuge tube rack comprises a centrifuge tube rack body, wherein the centrifuge tube rack body comprises a first surface and a second surface arranged opposite to each other, wherein the first surface and the second surface are both provided with a plurality of groups of tube holes for placing centrifuge tubes, and the apertures of each group of tube holes are different, and the four corners of the first surface and the second surface are each provided with a protrusion.

[0009] Preferably, the height of the protrusion is 1 to 2 mm.

[0010] Preferably, the height of the protrusion is 1.5 mm.

[0011] Preferably, one of the multiple groups of tube holes is used to place 0.2 ml centrifuge tubes, and the bottom wall of the tube holes in this group is provided with a raised platform.

[0012] Preferably, the cross section of the raised platform in the horizontal direction is cross-shaped, and its height is 2 to 3 mm.

[0013] Preferably, the height of the raised platform is 2.5 mm.

[0014] Preferably, one of the multiple groups of tube holes is used to place 0.5 ml centrifuge tubes, and the tube holes in this group include a plurality of tube hole units arranged in a rectangular array, and in each column, a weight-reducing hole is provided between two adjacent tube hole units.

[0015] Preferably, a connecting rib is provided in the middle of the outer wall of the centrifuge tube rack body.

[0016] Preferably, corresponding positions of each group of tube holes are provided with capacity marks.

[0017] Compared with the prior art, the centrifuge tube rack of the present invention has the following advantages: by providing protrusions on the four corners of the first and second surfaces of the centrifuge tube rack body, when the centrifuge tube rack body is light in weight and the porous design in the middle causes it to deform into a state with one side protruding and the other side concave, the protrusions support the test bench, allowing the centrifuge tube rack body to be fully supported, thereby enabling the centrifuge tube rack to be stably placed on the test bench. At the same time, by providing multiple groups of tube holes for placing centrifuge tubes on both the first and second surfaces, and each group of tube holes having a different aperture, tube holes of corresponding diameters can be selected according to actual needs to place centrifuge tubes and cryopreservation tubes, thereby being suitable for tubes of various specifications.

[0023] In this application, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0024] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0025] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figure 1-4 As shown, a centrifuge tube rack according to a preferred embodiment of the present invention includes a centrifuge tube rack body 1, wherein the centrifuge tube rack body 1 includes a first surface 14 and a second surface 15 arranged opposite to each other. The first surface 14 and the second surface 15 are each provided with a plurality of groups of tube holes 11 for placing centrifuge tubes, and the apertures of each group of tube holes 11 are different. Specifically, two, three, or four groups of tube holes 11 can be provided on each of the first surface 14 and the second surface 15, respectively, corresponding to the placement of microcentrifuge tubes 100 of various capacities such as 0.2ml, 0.5ml, 1.5ml, 2ml, and 5ml, as well as cryotubes of capacities such as 4.5ml, 2ml, and 1ml. A protrusion 12 is provided at each of the four corners of the first surface 14 and the second surface 15. The protrusion 12 can be configured to be arc-shaped and concentric with the corresponding tube hole 11; the protrusion 12 can also be configured to have a rectangular cross-section. The height of the protrusion 12 is 1 to 2 mm, such as 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, etc., preferably 1.5 mm.

[0027] The centrifuge tube rack based on the above-mentioned technical features has protrusions 12 provided at the four corners of the first surface 14 and the second surface 15 of the centrifuge tube rack body 1. When the centrifuge tube rack body 1, due to its light weight and the porous design in the middle, is deformed into a state with one side convex and the other side concave, the protrusions 12 support the centrifuge tube rack body 1 on the laboratory bench, fully supporting the centrifuge tube rack body 1, thereby enabling the centrifuge tube rack to be stably placed on the laboratory bench. Furthermore, by providing multiple groups of tube holes 11 for placing centrifuge tubes on each of the first surface 14 and the second surface 15, each group of tube holes 11 having a different aperture, tube holes 11 of corresponding diameters can be selected according to actual needs to place centrifuge tubes and cryopreservation tubes, thereby being suitable for tubes of various specifications.

[0028] In this embodiment, one of the multiple groups of tube holes 11 is used to accommodate a 0.2ml centrifuge tube 100. The bottom wall of this group of tube holes 11 is provided with a raised platform 13. Because a 0.2ml centrifuge tube has a very small capacity and a short tube body, in existing multifunctional microcentrifuge tube racks, directly placing a 0.2ml centrifuge tube 100 into a hole would cause the entire tube body of the centrifuge tube 100 to fall into the hole, with the tube mouth flush with the hole surface of the centrifuge tube rack, making it inconvenient to remove the centrifuge tube 100. By adding the raised platform 13, the tube mouth of the centrifuge tube 100 is higher than the upper end surface of the tube hole 11 of the centrifuge tube rack, making it easier to remove.

[0029] The horizontal cross section of the raised platform 13 is cross-shaped, and its height is 2-3 mm, such as 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, etc. Preferably, it is 2.5 mm, which is conducive to product injection molding.

[0030] In this embodiment, one of the multiple groups of wells 11 is used to accommodate 0.5ml centrifuge tubes 100. This group of wells 11 comprises a plurality of well units arranged in a rectangular array. Within each row, a weight-reducing hole 16 is provided between two adjacent well units. This reduces the weight of the microcentrifuge tube rack, creates a unique and aesthetically pleasing appearance, and reduces the amount of material used for injection molding. Furthermore, it ensures uniform wall thickness, preventing excessive localized plastic material buildup that could lead to severe shrinkage and deformation. This also shortens the injection molding cycle and facilitates molding.

[0031] In this embodiment, the plurality of groups of pores 11 each include a plurality of pore units, and the plurality of pore units are arranged in an array. The number of columns of each group of pore units is the same, and the number of rows can be the same or different. Letters such as A, B, C, D, E, F, and G can be set on the edge of the row number; Arabic numerals can be set on the edge of the row number as marks, so that each pore unit can be numbered with a letter and a number, which is convenient for marking centrifuge tubes. In addition, for different pore units, capacity marks can be set at the corresponding positions of each group of pores 11, so that the specifications of the centrifuge tubes or cryopreservation tubes corresponding to each pore 11 can be easily and intuitively understood.

[0032] In addition, the pore units on the first surface 14 and the second surface 15 are staggered to avoid interference with each other.

[0033] In this embodiment, a connecting rib 2 is provided in the middle of the outer wall of the centrifuge tube rack body 1, thereby improving the integrity of the centrifuge tube rack body 1 and thus improving the strength of the centrifuge tube rack.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
