A multifunctional biological material separation device

Abstract

The invention provides a multifunctional biological substance separating device, and belongs to the technical field of biology. The multifunctional biological substance separating device comprises a shell, a main shaft pushing rod, a return device, a magnetic sleeve connecting ring and an electric device, wherein the main shaft pushing rod penetrates through the shell; two ends of the main shaft pushing rod both stretch out of the shell; one end of the main shaft pushing rod is provided with a magnetic post; the magnetic sleeve connecting ring is arranged on the main shaft pushing rod in a sleeving way; one end, which is positioned outside the shell, of the magnetic sleeve connecting ring is provided with a magnetic sleeve; the return device is arranged in the shell and is used for enabling the main shaft pushing rod to move towards the direction which is far away from the magnetic sleeve; the electric device is connected with the magnetic sleeve connecting ring and is used for enabling the magnetic sleeve connecting ring (comprising the magnetic sleeve arranged thereon) to do rotary motion. The multifunctional biological substance separating device provided by the invention is particularly suitable for being applied to a process of extracting a nucleic acid through a paramagnetic particle method, has the effect of enabling a magnetic bead to be quickly separated from a system (mostly a lysis solution or an eluent) therein the magnetic bead exists and is compact in structure and convenient in operation.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a multifunctional biological substance separation device. Background technique [0002] In the field of biotechnology, the main operations currently used for the separation of substances include centrifugation, filtration, extraction, and electrophoresis. The principle of these methods is to separate different substances by the weight and diameter of solid substances. For example, the separation of substances in a centrifuge depends on the quality (specific gravity) of solid substances or liquid substances in the liquid, and different interfaces are produced under the action of centrifugal force to achieve the purpose of material separation; filtration (including sieving) is achieved by filter paper (filter membrane) The pore diameter and the diameter of the filtered material are used to achieve the purpose of material separation. In addition, there are drying, volatilization, extr...
