TECHNICAL FIELD

[0001] The utility model relates to sample processing equipment field, concretely relates to a sample protective solution quantitative adding device. BACKGROUND

[0002] In scientific research, medical detection, food inspection and many other fields, proper preservation and processing of various samples are crucial. In order to ensure the stability of the sample, prevent it from deteriorating or losing activity, it is usually necessary to add protective liquid to the sample. However, the existing sample protective liquid adding method has many shortcomings. The traditional manual adding method not only has low efficiency, but also it is difficult to ensure that the amount of protective liquid added each time is accurate and consistent. The skill level, operation habit and other factors of the operator will affect the amount of addition, which may lead to the situation of adding too much or too little. Adding too much will cause waste of protective liquid, increase cost, and may also interfere with the subsequent detection and analysis results; adding too little cannot achieve the expected protection effect, which may cause quality problems in the preservation and processing of the sample. Although some existing automatic adding equipment improves the adding efficiency to some extent, it still has shortcomings in quantitative accuracy. These devices are often complex in structure, high in maintenance cost, and lack of positioning accuracy, which makes it difficult to accurately add protective liquid to the specified position of each sample. In addition, some devices lack effective monitoring and feedback mechanism, which cannot timely find and correct the deviation in the adding process, resulting in unsatisfactory final adding effect.
