Problems solved by technology

However, washing takes a lot of time and may damage stem cells
In other words, during the washing process, the centrifuged material is manipulated several times and thus the stem cells are exposed to air for an extended period of time, thereby increasing the risk of contamination of the stem cells

Abstract

Provided is a centrifuge that can accurately and easily separate and collect layers of centrifuged material, the centrifuge including: a rotator comprising a receiving unit receiving materials inside and guiding the material to move upward by centrifugal force, and a rotator cover covering an upper portion of the receiving unit; and a container that is coupled to the rotator cover to be connected to the receiving unit and collects the material moved to the upper portion of the receiving unit. Also provided is a centrifuging method in which after centrifuging layers of the material by the centrifuge, the rotation speed of the centrifuge is reduced to separate a fluid to which a large centrifugal force is applied and a fluid to which a smaller centrifugal force is applied by adjusting the rotation speed, using the principle that centrifugal force during rotation varies according to specific gravity of components of a fluid, thereby accurately classifying and collecting layers of a desired material.

Description

technical field [0001] The present invention relates to a centrifugal separator and a centrifugal separation method that separates a fluid to which a large centrifugal force is applied from a fluid to which a small centrifugal force is applied by adjusting the rotational speed, using the principle that the centrifugal force changes according to the specific composition of the fluid during rotation of fluid. Therefore, by using the centrifuge and the centrifugal separation method, the material can be centrifuged and the material layers can be accurately and easily sorted and collected. Background technique [0002] The centrifuge and centrifugation method according to the present invention can be applied to any material that can move in a downward direction on a surface inclined to the direction of gravity, such as liquids, powders, gels, mixtures of liquids and solids, colloids, A solid in the shape of a sphere, etc. [0003] A centrifugal separator is a device used to sep...
