Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, and particularly relates to a multi-layer centrifuge. Background Art

[0002] An intelligent centrifuge is an analytical instrument used in the fields of biology and materials science. It has the function of high-speed rotation and is used for separating and purifying biological macromolecules and cell components. The main specifications and technical indicators of the intelligent centrifuge include the maximum rotation speed, the maximum relative centrifugal force, different rotors, and the temperature setting range, etc. These technical indicators enable the intelligent centrifuge to perform precise separation operations under a wide range of conditions. The main functions of the intelligent centrifuge include virus and subcellular component separation, protein gradient separation, lipoprotein separation, RNA gradient precipitation, etc. These functions are crucial for the research of proteomics, genomics, and cellomics.

[0003] During the process of centrifuging serum, an intelligent centrifuge is often used for serum separation. A sealed centrifuge bottle containing serum is placed in the centrifuge chamber of the intelligent centrifuge, and the intelligent centrifuge performs a centrifugal motion on the sealed centrifuge bottle of serum, thereby separating the serum. However, most of the existing intelligent centrifuges are single-layer structures and can only centrifuge four bottles at a time. If the number of bottles to be centrifuged is large, it will consume a lot of time and affect the speed of centrifuging serum. Therefore, the utility model provides a multi-layer centrifuge.

[0030] As Figures 1-5 shown, a multi-layer centrifuge includes a base 1. A rotating assembly is provided at the bottom of the base 1. A turntable 4 is provided at the top of the base 1 through the rotating assembly. A guiding assembly is provided inside the turntable 4, and the guiding assembly is connected to the base 1. A rotating column 8 is rotatably connected inside the turntable 4. A centrifugal plate 9 is fixedly installed on the surface of the rotating column 8.

A protective cover 17 is provided at the top of the base 1 through the lifting assembly. The number of turntables 4 is two. The number of centrifugal plates 9 on one turntable 4 is eight. Support legs 18 are fixedly installed at the bottom of the base 1. Anti-slip pads are provided at the bottoms of the support legs 18.

[0031] For this multi-layer centrifuge, sealed centrifuge bottles filled with serum are placed in the centrifugal grooves 10 of the eight centrifugal plates 9 on each turntable 4.
