Description

Technical Field

[0001] The utility model relates to the technical field of laboratory equipment, in particular to an inverted centrifuge tube rack. Background Art

[0002] In experiments or production processes in the fields of molecular biology, chemistry, chemical engineering, pharmaceuticals, and genetic engineering, there are often steps to control the liquid, dry the sample, and evaporate the residual solution (such as ethanol, isopropanol, etc.) after centrifugation and discarding the supernatant. This requires inverting the centrifuge tube after centrifugation and discarding the supernatant and holding it for a period of time to allow the residual solution in the tube to slowly flow down the tube wall and ultimately obtain a pure sediment at the bottom of the tube.

[0003] Currently, inverting multiple centrifuge tubes to drain the liquid requires first removing the tube caps and then placing the tubes upside down on a table. After a period of time, when the liquid control is complete, the tubes must be returned to the rack one by one. This process, which lacks specialized equipment, is cumbersome, labor-intensive, inefficient, and prone to knocking over tubes, causing confusion. To address this issue, we have developed an invertible centrifuge tube rack. Utility Model Content

[0004] The utility model provides an inverted centrifuge tube rack, which solves the technical problems raised by the background technology in the prior art.

[0022] Preferably, the lower end surfaces of the two triangular brackets 4 are fixedly connected with anti-skid pads 5. The provision of the anti-skid pads 5 can improve the stability of the entire centrifuge tube rack when it is placed.

[0023] Preferably, the centrifuge tube placement plate 1 is in the shape of a rectangle.

[0024] Preferably, the distance between the highest point of the triangular bracket 4 and the bottom edge is greater than half the width of the centrifuge tube placement plate 1.

[0025] The specific working principle and usage of this utility model are as follows:

[0026] The present invention provides an invertible centrifuge tube rack. When in use, first, the upper layer of liquid in each centrifuge tube that has been centrifuged is poured out, and then the uncovered centrifuge tube is inserted into the centrifuge tube hole 2 with a suitable aperture, with the pointed bottom of the centrifuge tube placed in the recess 9. At this time, the silicone fixing ring 3 can fix the centrifuge tube, and then the fastening bolt 8 is loosened. Then, the centrifuge tube placement plate 1 is rotated 180 degrees under the action of the rotating shaft 6, and the fastening bolt 8 is tightened to fix the rotating shaft 6, thereby fixing the centrifuge tube placement plate 1. In this way, the centrifuge tube can be completely inverted. Due to the fixing effect of the silicone fixing ring 3, the centrifuge tube will not fall or slip, thereby achieving the purpose of controlling the residual liquid in the centrifuge tube. According to different experimental requirements, the operator can rotate the centrifuge tube placement plate 1 to any angle between 90 and 180 degrees under the action of the rotating shaft 6. When the centrifuge tube reaches the required tilt angle, the centrifuge tube placement plate 1 is fixed with the fastening bolt 8. For example, the centrifuge tube plate 1 can be rotated 100 degrees, so that the centrifuge tubes are slightly tilted above the horizontal. Sterile gas can then be blown into the centrifuge tubes to accelerate the evaporation of residual liquid, shortening the experimental time and improving efficiency. Finally, when liquid control is complete, the fastening bolts 8 are loosened and the centrifuge tube plate 1 is flipped back to its normal angle, completing this step.

[0027] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
