Embodiment 1

[0029] Embodiment 1: A kind of multifunctional stratification instrument for ultrahigh-speed centrifugal liquid, see Figure 1 to Figure 5 , including a platform 1 provided with a platform support tube 5, a liquid inlet mechanism, a centrifuge tube fixing mechanism, and a layered liquid taking mechanism that are set on the platform 1 from top to bottom along the platform support tube 5; the liquid inlet mechanism includes Jacking bracket 12, the jacking bracket 12 is provided with a through hole forming a moving pair with the stand support tube 5, an adjusting nut 13 for fixing the position of the jacking bracket 12, and an oil drop hole through which the oil can pass. Pipe 21, the end seal 14 is provided between the oil drop hole and the liquid inlet pipe 21; the centrifuge tube fixing mechanism includes a bottom bracket 8 fixed on the stand support tube 5, and the bottom bracket 8 is provided with a through hole for clamping the centrifuge tube The layered liquid taking mech...

Embodiment 2

[0039] Embodiment 2: The principle of this embodiment is the same as that of Embodiment 1. The specific difference is that the layered liquid taking mechanism is replaced by a hinged connection with a detachable buckle, which saves the cost of parts processing.

Embodiment 3

[0040] Embodiment 3: The principle of this embodiment is the same as that of Embodiment 1. The specific difference is that the layered liquid taking mechanism is replaced by a hinged connection with a detachable buckle, which saves the cost of parts processing. The specific fastening is accomplished through buckles and slots provided at corresponding positions.

Abstract

The invention relates to a multi-function stratification instrument for ultra-high speed centrifugal liquid and a centrifugal liquid stratification method with an aim to solve the problem about difficulty in stratification of the ultra-high speed centrifugal liquid in the prior art. The multi-function stratification instrument comprises a stage provided with a stage supporting tube, and a liquid feed mechanism, a centrifugal tube fixing mechanism and a stratification liquid extraction mechanism are arranged on the stage in a sleeved manner along the stage supporting tube from top to bottom. The multi-function stratification instrument has the advantages of simple and ingenious structure, low manufacturing cost and wide application fields such as isolation of cells and organelle different in density, virus is isolated, and simpleness in operation is achieved; a control rod pries a metal block to protrude to have a puncture needle pushed up from the bottom, puncture is achieved, and strict training is avoided.

Description

technical field [0001] The invention relates to the field of centrifugal separation equipment, in particular to a multifunctional layering instrument for ultrahigh-speed centrifugal liquid and a method for layering centrifugal liquid. Background technique [0002] Centrifugal separation is a physical separation and analysis technique that uses the difference in density, shape and size of different substances to separate and extract different particles in suspension with centrifugal force field. It is widely used in biology (bioengineering and biological products, etc.), Medicine, chemistry, chemical industry and other fields. A centrifuge is a machine that uses centrifugal force to separate components in a mixture of liquid and solid particles or liquid and liquid. [0003] According to the separation factor Fr value (referring to the ratio of the centrifugal force of the material in the centrifugal force field to the gravity of the material in the gravity field), the centr...
