Technical Field
[0001] The utility model relates to the technical field of centrifuges with a perspective window door body, in particular to a centrifuge with a perspective window door body. Background Art
[0002] A centrifuge is a machine that uses centrifugal force to separate the components in a mixture of liquid and solid particles or liquid and liquid. Centrifuges are mainly used to separate solid particles from a suspension from the liquid, or to separate two immiscible liquids with different densities in an emulsion (for example, to separate cream from milk); it can also be used to remove the liquid from wet solids, such as spinning dry clothes in a washing machine; special ultra-high-speed tubular separators can also separate gas mixtures with different densities; by taking advantage of the fact that solid particles with different densities or particle sizes have different sedimentation rates in a liquid, some sedimentation centrifuges can also classify solid particles according to density or particle size.
[0003] The inventor found during daily use of the centrifuge that when centrifuging solids inside a liquid, the test tube needs to be fixed inside the centrifuge's centrifuge rack. Since the centrifuge operates by centrifugal force, the test tube needs to be firmly fixed inside the centrifuge rack. As a result, after centrifugation, it is inconvenient to remove the test tube from inside the centrifuge rack, which causes an impact. Summary of the Utility Model
