Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, specifically to a multifunctional support for balancing centrifuge tubes in an ultra-high-speed centrifuge. Background Technology

[0002] Ultracentrifugation is an indispensable core separation method in biomedicine, chemical analysis, and clinical testing. It utilizes the immense centrifugal force generated by extremely high-speed rotation to achieve rapid separation, concentration, and purification of samples, and is widely used in precision experiments such as virus purification, organelle separation, and protein crystallization. With the diversification of research needs, ultracentrifuges require adaptability to different rotor and centrifuge tube specifications (such as the fixed-angle rotor and horizontal rotor of the BECKMAN series centrifuges, which correspond to various tube types) to meet the experimental requirements of different capacities and speeds. However, the safety of centrifuge operation and the accuracy of experimental results highly depend on the standardization of sample balancing operations, ensuring that the mass difference of symmetrically placed centrifuge tubes is strictly controlled within allowable limits.

[0003] Currently, there is a lack of dedicated balancing racks on the market designed for the various sizes of centrifuge tubes used in BECKMAN ultra-high-speed centrifuges. Researchers typically use temporary alternatives for balancing, such as placing the centrifuge tubes on foam boards, beakers, or general-purpose centrifuge tube racks for weighing.

[0004] However, such methods are inconvenient to operate and prone to sample leakage due to collisions caused by unsuitable size. Utility Model Content

[0005] The purpose of this invention is to provide a multi-functional support for balancing centrifuge tubes in ultra-high-speed centrifuges, so as to solve the problem that there is no dedicated balancing support for BECKMAN ultra-high-speed centrifuges in the prior art.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: The support base is fixedly equipped with a cover holder assembly and a centrifuge tube holder assembly. The first cover holder is a cylindrical barrel-shaped structure with three arc-shaped grooves and one "U"-shaped groove on the top, the structure and position of which correspond to the basket cover. The second cover holder is a rounded rectangular platform with a sloping groove on the top, and arc-shaped grooves on three sides of the sloping groove, the structure and position of which correspond to the basket cover.

[0007] Furthermore, the centrifuge tube support assembly includes a first centrifuge tube support, a second centrifuge tube support, a third centrifuge tube support, and a fourth centrifuge tube support. All centrifuge tube supports are cylindrical barrel-shaped structures, and the inner diameters of the different centrifuge tube supports are different.

[0008] Furthermore, the support base is a rounded rectangular plate, and the side without the centrifuge tube support assembly is provided with a rubber anti-slip pad.

[0009] Furthermore, the cover holder assembly includes a first cover holder and a second cover holder.

[0010] Furthermore, the bottoms of the first centrifuge tube support, the second centrifuge tube support, the third centrifuge tube support, and the fourth centrifuge tube support are all arc-shaped supports that match the centrifuge tubes.

[0011] This utility model has the following beneficial effects: This invention effectively solves the problems of sample leakage, weighing errors, and safety hazards caused by the mismatch of temporary support dimensions during the balancing operation of multi-specification centrifuge tubes in BECKMAN ultra-high-speed centrifuges. The support can accurately accommodate centrifuge tubes of different specifications, avoiding tube tilting or collision. Its rapid positioning function simplifies the operation process, significantly improves balancing efficiency, and reduces the risk of equipment imbalance caused by manual adjustment errors.

Detailed Implementation

[0013] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] Example 1: As attached Figure 1-2 As shown, a cover holder assembly and a centrifuge tube holder assembly are fixedly installed on the support base. The support base 1 is a rounded rectangular plate with dimensions of 10cm*8cm. It is made of lightweight and high-strength ABS engineering plastic. A rubber anti-slip pad is attached to the side of the bottom where the centrifuge tube holder assembly is not installed to enhance the stability of the balance during weighing.

[0015] In addition, the centrifuge tube support assembly includes a first centrifuge tube support 4, a second centrifuge tube support 5, a third centrifuge tube support 6, and a fourth centrifuge tube support 7. In this embodiment, the inner diameters of each support are 8mm, 12mm, 16mm, and 20mm, respectively. In this embodiment, they are adapted to centrifuge tubes of six types of rotors: SW32Ti, SW40Ti, SW41Ti, SW45Ti, Type70Ti, and Type90Ti. Among them, SW40Ti and SW41Ti share the fourth centrifuge tube support 7. In addition, the first cap holder 2 is also adapted to Type70Ti centrifuge tubes. All centrifuge tube supports are cylindrical barrel-shaped structures with different inner diameters between different centrifuge tube supports. The bottom of each support is designed as an arc-shaped support with the same curvature as the bottom of the centrifuge tube to avoid tube slippage or concentrated stress.

[0016] Furthermore, the cover holder assembly includes a first cover holder 2 and a second cover holder 3. The first cover holder 2 is a cylindrical barrel-shaped structure with three arc-shaped grooves and one "U"-shaped groove on the top. The structure and position of the grooves correspond to the basket cover. While the first cover holder 2 can hold the basket cover, its cylindrical barrel-shaped structure can also be used to hold centrifuge tubes. The second cover holder 3 is a rounded rectangular platform with a sloping groove on the top. Arc-shaped grooves are provided on three sides of the sloping groove. The structure and position of the sloping groove and the arc-shaped grooves correspond to the basket cover.

[0017] The specific method of using this utility model is as follows: Invert the centrifuge basket lid into the corresponding groove of the first lid holder 2 or the second lid holder 3 to prevent the lid from tipping over. Then, select a centrifuge tube holder with the corresponding inner diameter according to the centrifuge tube specifications, and vertically embed the centrifuge tubes into the holder, using the arc-shaped bottom and side walls for stable fixation. Finally, place the entire holder on the electronic balance, place the centrifuge tubes, and add samples.

[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
