Description

technical field [0001] The invention relates to the technical field of experimental instruments, in particular to a multifunctional liquid reaction device. Background technique [0002] In biochemistry teaching or scientific research, experimenters often need to add two or more reagents to mix, or stand still, or heat to a constant temperature, and keep it for a certain period of time when performing a certain biochemical experiment, and finally according to a certain phenomenon Or concentration to get experimental results. During this process, experimenters usually use manual methods to add and mix liquids with test instruments such as measuring cylinders, measuring bottles, and droppers. This method of operation causes many human interference factors. When manually adding reagents, errors often occur randomly with the mood, technique, proficiency, and operating habits of the experimenters, and are uncontrollable. Therefore, the results under the same experimental conditio...

Problems solved by technology

This method of operation causes many human interference factors. When manually adding reagents, errors often occur randomly with the mood, technique, proficiency, and operating habits of the experimenters, and are uncontrollable. Therefore, the results under the same experimental conditions are different, and even Large errors occur

[0003] At the same time, usually when doing biochemical experiments, a large number of repeated experiments are often required for experiments with the same experimental conditions, and a large number of repetitive tasks such as reagent addition, constant temperature digestion, and result judgment also require manual participation, which adds a lot of work to the experimenters. quantity

[0004] In addition, in the digestion process of biochemical experiments, the reagents are usually put into test tubes and then digested with the help of specific digestion instruments. Some experiments require higher digestion temperatures, or some reagents are highly corrosive and toxic, so in The moving process of the test tube is more dangerous and may cause personal injury
