Automatic balancing instrument for centrifugal tube

Abstract

The invention provides an automatic balancing instrument for a centrifuge tube. The automatic balancing instrument comprises a shell internally provided with a plurality of balancing sample grooves, and a balancing liquid container and liquid outlet pipes are arranged on the top of the shell; the multiple liquid outlet pipes are arranged and correspond to the balancing sample grooves one by one, and the balancing liquid container is provided with a liquid outlet mechanism for controlling a liquid outlet of the balancing liquid container to open and close; and a detection mechanism used for detecting the conditions of balancing samples in the balancing sample grooves is arranged in the shell, and the liquid outlet mechanism is electrically connected with the detection mechanism. Synchronous balancing of a plurality of centrifugal pipes can be achieved through one balancing liquid container and the multiple liquid outlet pipes, and the detection mechanism is used for detecting and feeding back the weight, liquid level and bubble condition of the balancing samples of the centrifugal pipes in the balancing sample grooves, so that the liquid outlet amount of the balancing liquid container is regulated; the balancing precision is high, and centrifugal separation quality can be improved; The implementation reproducibility is improved, and the requirement for ultra-high-speed centrifugation is met; repeated manual balancing is not needed, and manual operation is reduced; and the balancing efficiency is improved.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to an automatic balancer for centrifuge tubes. Background technique [0002] A centrifuge is a machine that uses centrifugal force to separate components in a mixture of liquid and solid particles or liquid and liquid. Trimming is a necessary step for centrifugal operation. During the operation of the centrifuge, if there is no trimming, the torque on the shaft will be different. The rotor will cause greater wear to the shaft. Long-term wear will reduce the service life of the centrifuge, and the trimmed centrifuge tube can ensure the stability of the shaft when the centrifuge rotates at high speed, and also make the final centrifuge speed reach the preset value of the centrifuge to ensure the separation effect. [0003] Among them, low-speed centrifugation (less than 3000rpm) has relatively low requirements for trimming, which can meet the experimental requirements through...

AI Technical Summary

Problems solved by technology

The existing trim still needs to be manually operated, but manual trim needs to be repeatedly trimmed, which is time-consuming and laborious, and it is difficult to quickly meet the trim requirements of high-speed centrifugation, and the long-term trim makes the sample exposed to the air, resulting in sample degradation and concentration drop And damage the sample, etc., which will not be conducive to the control of test variables, and make the follow-up test results have a large error
