Description

Technical Field

[0002] Automated sampling systems are widely used in fields such as biomedicine and chemical analysis. The sample tray, a key component of such systems, is used to hold and position reagent tubes or other sample containers. Traditional sample trays are typically fixed in structure and can only accommodate reagent tubes of specific sizes. When different lengths or specifications of reagent tubes are needed, different sample trays must be used, which is cumbersome, inefficient, and prone to human error. Furthermore, traditional sample trays have low positioning accuracy, which can easily cause the sampling needle to deviate from the target position, affecting the accuracy of the sampling results.

[0003] Therefore, this application provides a high-precision adjustable sample disk to solve the technical problems existing in the background art. Utility Model Content
