Description

Technical Field

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

[0002] Centrifuge tube racks are essential tools for biological science and technology laboratories that use centrifuge tubes. They are used to support centrifuge tubes of different sizes during sample processing, making it easier for experimenters to process samples. Since existing centrifuge tubes are of standard design, the main volume types are 0.2 ml, 0.5 ml and 2 ml, which are used to process and store biological samples. Currently, the two centrifuge tube racks are based on the design of ThermoFisher as the mainstream design, but this design has the following defects:

[0003] The centrifuge tube slots have openings that are all on the same plane, which is not conducive to the classification and processing of centrifuge tubes. It is easy to take the wrong centrifuge tube when operating multiple samples, resulting in experimental errors. The distance between adjacent centrifuge tube slots is too close, which makes it easy to mistakenly take and overturn adjacent centrifuge tubes during operation. The centrifuge tube slots are too deep, making it difficult to take out the centrifuge tubes. The base and upper part of the centrifuge tube are consistent in size, which makes them unstable and easy to overturn. Utility Model Content

[0004] The utility model aims to provide a centrifuge tube rack to overcome the defects of the prior art that the centrifuge tube slot openings are all on the same plane, which is not conducive to the classification and processing of the centrifuge tubes, and it is easy to take the wrong centrifuge tube when operating multiple samples, resulting in experimental errors.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A centrifuge tube rack comprises a base and an inclined fixing portion and a horizontal spacing portion on the base, wherein the inclined fixing portion and the horizontal spacing portion are alternately distributed and are in a stepped shape as a whole, and the inclined fixing portion is provided with a fixing hole matching the shape of the centrifuge tube, the central axis of the fixing hole is perpendicular to the plane where the horizontal spacing portion is located, and the diameters of the fixing holes located on the same inclined fixing portion are the same.

[0007] Preferably, the spacing between adjacent fixing holes on the same inclined fixing portion is 18-22 mm.

[0008] Preferably, the angle between the upper end surface of the inclined fixing portion and the horizontal plane is in the range of 25-35 degrees.

[0009] Preferably, there are multiple inclined fixing parts, and the upper end surfaces of the inclined fixing parts are parallel to each other.

[0010] Preferably, the diameter of the fixing hole on the inclined fixing portion is in the range of 5-12 mm.

[0011] Preferably, the horizontal spacing portion includes a first horizontal portion and a second horizontal portion, the first horizontal portion is located between the two inclined fixing portions, and the second horizontal portion is located at the rear end of the uppermost inclined fixing portion.

[0012] Preferably, the width of the first horizontal portion is 18-22 mm.

[0013] Preferably, a pipe row groove is provided on the first horizontal portion, and the width of the pipe row groove is 8.8-9.4 mm.

[0014] Preferably, a fixing groove matching the shape of the centrifuge tube is provided on the second horizontal portion, and the diameter of the fixing groove is greater than 12 mm.

[0015] Preferably, the pipe rack is made of antistatic plastic.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] (1) This solution places centrifuge tubes of different diameters in corresponding fixing holes. When taking the centrifuge tubes, centrifuge tubes of the same specifications are placed in the fixing holes on the same inclined fixing part. The corresponding centrifuge tubes are taken from different inclined fixing parts as needed. The arrangement of the centrifuge tubes is more regular, reducing the risk of taking the wrong ones.

[0018] A horizontal spacing part is arranged between two adjacent inclined fixing parts to increase the spacing between the fixing holes of centrifuge tubes of different specifications, further reducing the risk of taking the wrong one, and providing more operating space, thereby improving the convenience and safety of placing and taking the centrifuge tube. A certain angle is formed between the upper end surface of the inclined fixing part and the cross section of the centrifuge tube, so that the fixing hole is lower in front and higher in the back, and the length of the centrifuge tube placed in the fixing hole is reduced, ensuring the fixing stability while making it easier to take out.

[0019] (2) In this solution, a long strip of tube arrangement groove is provided on the first plane portion to place the row of centrifuge tubes, which facilitates the placement of the row of centrifuge tubes and the sample aspiration. Since the 50ml and 15ml centrifuge tubes are large in size, it is inconvenient to set a fixing hole on the inclined fixing portion. In this application, a fixing groove is provided on the second plane portion, and the centrifuge tubes are placed in the fixing groove. The 50ml and 15ml centrifuge tubes can be used for sample processing and can also be used for temporary storage of waste liquid in sample processing. The tube rack has a wider range of application and is more practical.

[0020] (3) The traditional centrifuge tube rack is made of antistatic polyvinyl chloride plastic material, which is easy to generate static electricity and electrostatically repel the plastic centrifuge tube, resulting in unstable placement of the centrifuge tube. The centrifuge tube rack of this solution uses a material that reduces static electricity with the centrifuge tube, such as a plastic rack, to reduce the electrostatic repulsion between the rack and the centrifuge tube and improve the stability of the centrifuge tube support.

[0029] Example 1

[0030] like Figure 1 As shown, this embodiment provides a centrifuge tube rack, including a base 1 and an inclined fixing portion 2 and a horizontal spacer portion 3 on the base 1, the inclined fixing portion 2 and the horizontal spacer portion 3 are alternately distributed and are stepped as a whole, and a fixing hole 4 matching the shape of the centrifuge tube is provided on the inclined fixing portion 2, the central axis of the fixing hole 4 is perpendicular to the plane where the horizontal spacer portion 3 is located, and the diameters of the fixing holes 4 located on the same inclined fixing portion 2 are the same.

[0031] Working principle: Place centrifuge tubes with different diameters in the corresponding fixing holes 4. When taking out the centrifuge tubes, place centrifuge tubes of the same specifications in the fixing holes 4 on the same inclined fixing part 2, and take out the corresponding centrifuge tubes from different inclined fixing parts 2 as needed.

[0032] By placing centrifuge tubes of different diameters in corresponding fixing holes 4, when taking out centrifuge tubes, centrifuge tubes of the same specifications are placed in the fixing holes 4 on the same inclined fixing part 2, and corresponding centrifuge tubes are taken from different inclined fixing parts 2 as needed. The arrangement of centrifuge tubes is more regular, reducing the risk of taking wrong ones. A horizontal spacing part 3 is set between two adjacent inclined fixing parts 2 to increase the spacing between the fixing holes 4 of centrifuge tubes of different specifications, further reducing the risk of taking wrong ones, and providing a larger operating space, thereby improving the convenience and safety of placing and taking out the centrifuge tubes. A certain angle is formed between the upper end surface of the inclined fixing part 2 and the cross section of the centrifuge tube, so that the fixing hole 4 is lower in front and higher in the back, and the length of the centrifuge tube placed in the fixing hole 4 is reduced, ensuring the stability of the fixation while making it more convenient to take out.

[0033] Specifically, the spacing between adjacent fixing holes 4 on the same inclined fixing part 2 is 20 mm. The angle between the upper end surface of the inclined fixing part 2 and the horizontal plane is 30 degrees. There are multiple inclined fixing parts 2, and the upper end surfaces of the inclined fixing parts 2 are parallel to each other.

[0034] This tube rack adopts a design of staggered inclined planes. In order to easily separate centrifuge tubes in different columns in the longitudinal space, different centrifuge tube slots are arranged on inclined planes of different steps. Tube slots of the same volume but different columns are arranged in a slope-like manner. At the same time, centrifuge tubes in different rows are separated by planes, which makes it easy to separate different tube slots in the longitudinal direction, reduce the situation of mistaking centrifuge tubes between columns, and make it easy to take centrifuge tubes.

[0035] The base of the traditional centrifuge tube rack is not stable enough. The base of the utility model is designed with a slope to increase the stability of the rack during operation. The slope angle of the inclined fixing part is 30 degrees, which increases the stability of the base and reduces the space occupied by the test bench.

[0036] The diameter of the fixing hole 4 on the inclined fixing portion 2 is in the range of 5-12 mm.

[0037] The centrifuge tube rack is provided with fixing holes of corresponding diameters according to the centrifuge tubes of different volumes. The fixing holes 4 in the utility model can be used for supporting and placing 0.2ml, 0.5ml, and 2ml centrifuge tubes, and has a wide range of applications and strong practicality.

[0038] The opening of the fixing hole is oval, and the rear height is higher than the front height, so that the rear of the tube slot supports the centrifuge tube, while the front height is lower, which is convenient for taking the centrifuge tube. Since the diameter of the centrifuge tube cover is larger than the diameter of the centrifuge tube, the depth of the tube slot is slightly lower than the centrifuge tube cover, which is convenient for placing the centrifuge tube in the tube slot.

[0039] In a preferred embodiment, the horizontal spacer 3 includes a first horizontal portion 31 and a second horizontal portion 32. The first horizontal portion 31 is located between the two inclined fixing portions 2, and the second horizontal portion 32 is located at one end of the inclined fixing portion 2. The width of the first horizontal portion 31 is 20 mm.

[0040] Furthermore, a pipe arrangement groove 33 is provided on the first horizontal portion 31 , and the width of the pipe arrangement groove 33 is 9.1 mm.

[0041] Furthermore, a fixing groove 34 matching the shape of the centrifuge tube is provided on the second horizontal portion 32, and the diameter of the fixing groove 34 is greater than 12 mm.

[0042] In this solution, a long strip of tube arrangement groove is provided on the first plane part to place the row of centrifuge tubes, which is convenient for placing the row of centrifuge tubes and sample aspiration. Since the 50ml and 15ml centrifuge tubes are large in size, it is inconvenient to set a fixing hole on the inclined fixing part. In this application, a fixing groove is provided on the second plane part, and the centrifuge tubes are placed in the fixing groove. The 50ml and 15ml centrifuge tubes can be used for sample processing and can also be used for temporary storage of waste liquid in sample processing.

[0043] In a preferred embodiment, the material of the pipe rack is antistatic plastic.

[0044] The centrifuge tube rack uses materials that reduce static electricity with the centrifuge tube, such as anti-static plastic material, to reduce the electrostatic repulsion between the rack and the centrifuge tube and improve the stability of the centrifuge tube support.

[0045] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
