A centrifuge tube fixing device for an ultrasonic cell disruptor

Abstract

A centrifuge tube fixing device, belonging to the field of experimental apparatus, addresses the problem of centrifuge tubes easily tipping over in an ultrasonic cell disruptor. This invention provides a centrifuge tube fixing device comprising a four-legged support and two sizes of centrifuge tube fixing rings. The four legs of the four-legged support can support the centrifuge tubes at the angle between the inner wall and the bottom of a 1L plastic measuring cup. The upper part of the four-legged support has a centrifuge tube fixing ring that can be detachably connected to the two sizes of centrifuge tube fixing rings via a right-angle tenon joint. The centrifuge tube fixing rings are available in two sizes, one for 15mL centrifuge tubes and the other for 50mL centrifuge tubes. The inner diameter of both sizes of the fixing ring is 2mm smaller than the outer diameter of the corresponding centrifuge tube. The elastic deformation caused by inserting the centrifuge tube into the fixing ring compresses and fixes the centrifuge tube within the fixing ring. This invention supports and fixes the centrifuge tubes within a 1L plastic beaker, preventing them from tilting.

Description

Technical Field

[0001] This utility model relates to the field of experimental apparatus, and in particular to a centrifuge tube fixing device for an ultrasonic cell disruptor. Background Technology

[0002] Existing ultrasonic cell disruptors, when disrupting cell suspensions in 50mL or 15mL centrifuge tubes, even with the tubes vertically inserted into a container filled with crushed ice, cause the tubes to vibrate and generate heat due to the ultrasound. This melts the ice supporting the tubes, causing them to lose support and tilt. Consequently, the inner wall of the tube comes into contact with the ultrasonic needle emitting the sound, producing a loud, piercing noise that can harm the hearing of laboratory personnel. Furthermore, frequent opening of the disruptor's door to straighten the tubes wastes time. Summary of the Invention

[0003] To overcome the problem of centrifuge tubes easily tipping over in an ultrasonic cell disruptor, this invention provides a centrifuge tube fixing device for an ultrasonic cell disruptor.

[0004] A centrifuge tube fixing device for an ultrasonic cell disruptor includes a four-legged support, centrifuge tube fixing rings for 50mL and 15mL centrifuge tubes. The four-legged support includes an upper centrifuge tube fixing ring holder and four lower support legs. The four support legs can support a 1L plastic measuring cup. The upper centrifuge tube fixing ring holder can be connected to a detachable centrifuge tube fixing ring via a right-angle tenon. The centrifuge tube fixing rings are available in two sizes: one for 50mL and one for 15mL centrifuge tubes. The inner diameter of both sizes is 2mm smaller than the outer diameter of the corresponding centrifuge tube. The centrifuge tube is secured within the fixing ring by the elastic deformation caused by inserting the centrifuge tube into it.

[0005] The right-angle tenon structure has four parts.

[0006] The ends of the four support legs are rounded.

[0007] Compared with the prior art, the beneficial effects of this invention are: This utility model, by supporting and fixing the centrifuge tube, secures the centrifuge tube to the center of a 1L plastic beaker without tilting. This solves the problem that centrifuge tubes easily tilt, and when tilted, the inner wall of the centrifuge tube contacts the needle of the ultrasonic cell disruptor, emitting a loud, piercing noise. This necessitates frequent opening of the ultrasonic cell disruptor lid to straighten the centrifuge tube, harming the auditory health of researchers and wasting time. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Reference Figure 1-10 A centrifuge tube fixing device for an ultrasonic cell disruptor includes a four-legged support, a centrifuge tube fixing ring 3 for 50mL centrifuge tubes, and a centrifuge tube fixing ring 4 for 15mL centrifuge tubes. The four-legged support includes an upper centrifuge tube fixing ring placement ring 1 and four lower support legs 2. The four support legs 2 of the four-legged support can support a 1L capacity plastic measuring cup. The upper centrifuge tube fixing ring placement ring 1 of the four-legged support is internally connected to two detachable centrifuge tube fixing rings of different sizes via right-angle tenons 12. The centrifuge tube fixing rings are available in two sizes: centrifuge tube fixing ring 3 for 50mL centrifuge tubes and centrifuge tube fixing ring 4 for 15mL centrifuge tubes. Both are made of rubber, and the inner diameter of both sizes of centrifuge tube fixing rings is 2mm smaller than the outer diameter of the corresponding centrifuge tube. Four right-angle tenon structures are provided. The ends of the four support legs 22 of the four-legged support are rounded.

[0022] Working principle: In use, insert 50mL or 15mL centrifuge tubes containing cell suspension into the corresponding centrifuge tube retaining ring. The elastic deformation of the retaining ring caused by the insertion of the centrifuge tube compresses and fixes the centrifuge tube within the ring. Then, connect the centrifuge tube retaining ring to the upper centrifuge tube retaining ring 1 of the four-legged stand using a right-angle tenon 12 connection. Next, place the entire device into a 1L plastic measuring cup containing crushed ice. This fixes the centrifuge tubes in the center of the measuring cup, preventing the centrifuge tubes from tilting due to the melting of the crushed ice caused by ultrasonic grinding.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
