Centrifuge tube automatic balancer

Abstract

The application provides an automatic balancer for centrifuge tubes, which includes a housing with multiple trimming sample tanks inside. The top of the housing is provided with a trimming liquid container and a liquid outlet pipe. There are multiple liquid outlet pipes that correspond to the trimming sample tanks one by one. Set, the trim fluid container is provided with a liquid outlet mechanism that controls the on-off of the trim fluid container, and the housing is provided with a detection mechanism that detects the condition of the trim samples in a plurality of trim sample tanks, and the liquid outlet mechanism is electrically connected to the detection mechanism. Synchronous balance of multiple centrifuge tubes can be realized through a balance liquid container and multiple outlet pipes, and the detection mechanism is used to detect and feed back the weight, liquid level and air bubbles of the balance samples of the centrifuge tubes in each balance sample tank to adjust the balance The output volume of the liquid container and the trimming accuracy are high, which helps to improve the quality of centrifugation and the reproducibility of the realization, which is suitable for the requirements of ultra-high-speed centrifugation, and does not require manual repeated trimming, which reduces manual operations and improves trimming efficiency. .

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
