High-speed centrifugal DNA extraction device

Abstract

The invention discloses a high-speed centrifugal DNA extraction device. The high-speed centrifugal DNA extraction device comprises a box shell, a fixing chuck and a triangular bottom plate, wherein astorage groove is formed in the middle position of the inner side of the upper end of the box shell, the fixing chuck is movably installed on the inner side of the storage groove, the triangular bottom plate is arranged on the lower part of the fixing chuck, the fixing chuck is fixed to the box shell through the triangular bottom plate in an abutting against mode, three sets of supporting foot rods fixedly sleeve the outer surfaces of the bottom of the triangular bottom plate, lifting sleeves movably sleeve the outer surfaces of the side edges of the supporting foot rods, spring sleeves are fixedly connected with the parts, close to the upper parts of the lifting sleeves, of the outer surfaces of the side edges of the supporting foot rods, and a motor is fixedly installed in the middle position of the outer surface of the lower end of the triangular bottom plate. According to the high-speed centrifugal DNA extraction device, the DNA extraction device can be provided with a combined fixing structure, so that the DNA extraction device can be suitable for test tube containers of different sizes, meanwhile, the DNA extraction device is provided with an auxiliary fixing structure, and the stability of the DNA extraction device during operation is improved.

Description

technical field [0001] The invention belongs to the technical field of DNA extracting device processing, in particular to a high-speed centrifugal DNA extracting device. Background technique [0002] Centrifugal extraction technology is a practical technology to realize liquid-liquid two-phase contact mass transfer and phase separation with the help of centrifugal force field. It is a new type of high-efficiency separation technology combining liquid extraction and centrifugal technology. Compared with other extraction technologies, it has two advantages: The contact time of phase materials is short, the phase separation speed is fast, the storage volume in the equipment is small, and the operation range is wide. [0003] The comparative document CN208120999U discloses a centrifugal extraction device for aquatic collagen, which includes a frame, the inner bottom wall is fixedly connected with a sleeve, and the end of the sleeve far away from the frame is sleeved with a first...

AI Technical Summary

Problems solved by technology

The utility model solves the problem that the centrifugal extraction equipment for aquatic collagen is slow due to the reduced efficiency of centrifugal extraction, thereby affecting the production efficiency of aquatic collagen. Compared with the present invention, it does not have a combined fixed structure , making it impossible to use different sized test tube containers

[0004] The existing high-speed centrifugal DNA extraction device has certain disadvantages in the process of use. The traditional high-speed centrifugal DNA extraction device adopts a fixed structure design, so that the traditional high-speed centrifugal DNA extraction device can only be applied to test tube containers with fixed specifications. , thereby reducing the scope of application of the high-speed centrifugal DNA extraction device; secondly, the traditional high-speed centrifugal DNA extraction device does not have a buffer protection structure, which makes the traditional high-speed centrifugal DNA extraction device prone to shaking during high-speed rotation; The type DNA extraction device does not have an auxiliary fixed structure, which reduces its stability during use
