Description

Multichannel centrifuge rotor

Technical Field

The utility model relates to an experimental facilities field, especially a multichannel centrifuge rotor.

Background

The centrifugal machine is widely used in the fields of medical treatment, colleges and universities, scientific research units, biopharmaceuticals, fine chemical engineering, food, environmental protection, genetic engineering and the like, at present, more than fifty varieties of centrifugal machine products exist in China, and the centrifugal machine can be divided into a table type centrifugal machine and a floor type centrifugal machine according to the structure; it can be divided into low-speed centrifuge, high-speed centrifuge, ultracentrifuge and ultrahigh-speed centrifuge according to different rotation speeds.

At present, the research on the centrifugal machine at home and abroad is mainly put on the aspects of mechanical safety design, highest safe use rotating speed, centrifugal machine protection system and the like of a centrifugal rotor. The difference between domestic products and international brands is mainly the quality of the drive motor and the highest index of the rotor, and the corresponding technological strength is required. The composite material turning head has certain gap with the foreign advanced level. In recent years, the requirements of laboratories on applied separation technology are continuously increased, which puts higher requirements on the development and technical level of laboratory centrifuge manufacturing enterprises, and the laboratory centrifuges are developed towards higher speed, more precision, multiple purposes and full-functional types in the future.

The choice of laboratory centrifuges mainly takes into account several aspects: the machine type, such as the rotary head, the rotating speed, the capacity, the temperature and the like, is determined according to the actual application requirements, and the large-capacity and micro-centrifuge are deeply welcomed by scientific research laboratories by being provided with a plurality of rotary heads, but the price is relatively high. The centrifuge rotor is not suitable for buying, and the service life of the rotor is limited by the centrifugation times and time, and the rotor is expensive, so that the commonly used rotor is selected and purchased mainly according to experimental requirements. To the laboratory, purchase multiple commentaries on classics and not only increased the experiment cost, need often change the commentaries on classics in the use moreover, prolong the experiment cycle, reduce experiment efficiency.

In order to solve the above problems, people are always seeking an ideal technical solution.

SUMMERY OF THE UTILITY MODEL

In order to realize the purpose, the utility model discloses the technical scheme who adopts is: a multichannel centrifuge rotor comprises a centrifuge turntable and a plurality of groups of test tube placing cavities uniformly arranged on the centrifuge turntable, wherein a rotating shaft is arranged at the center of the centrifuge turntable, the plurality of groups of test tube placing cavities are arrayed on the centrifuge turntable in an equidistant circular manner by taking the axis of the rotating shaft as the center, and the plurality of groups of test tube placing cavities form an inner ring test tube placing cavity group, a middle ring test tube placing cavity group and an outer ring test tube placing cavity group;

wherein, the test tube that is arranged in the inner circle test tube and places the chamber in the chamber group, the test tube that is arranged in the well circle test tube and places the chamber in the chamber group and the outer lane test tube place the chamber in the chamber group and place the chamber edge the radial direction of centrifuge carousel sets up side by side.

Based on the above, multichannel centrifuge rotor still establish including the cover the protection casing of centrifuge rotor carousel outside.

Based on the above, the top surface of centrifuge carousel is the arcwall face of indent.

Based on the above, the diameter that the chamber was placed to the test tube that is arranged in the inner circle test tube placing chamber group, the diameter that the chamber was placed to the test tube that is arranged in the well circle test tube placing chamber group, the diameter that the chamber was placed to the test tube that is arranged in the outer lane test tube placing chamber group reduced in proper order.

Compared with the prior art, the utility model has the advantages of substantive characteristics and progress, specifically speaking, the utility model provides a multichannel centrifuge rotor places the chamber through setting up the multiunit test tube on the centrifuge carousel, the multiunit the test tube place the chamber with the axis of rotation axis is equidistant circular array in the center on the centrifuge carousel, and the diameter that the chamber was placed to the test tube reduces from inboard outside in proper order, can realize carrying out centrifugal processing with the test tube of different specifications on same rotor, need not change in the use and turn round and reduce the capital cost, improved experimental efficiency simultaneously.
