Description

Technical Field

[0001] The utility model belongs to the technical field of drug inspection, and in particular relates to a drug inspection and analysis titration device. Background Art

[0002] The inspection of drugs usually uses titration for quantitative analysis. Titration is a means of quantitative analysis and also a chemical experimental operation. It determines the content of a certain solute through the quantitative reaction of two solutions. It indicates the titration endpoint based on the color change of the indicator, and then visually observes the volume consumed by the standard solution and calculates the analysis result.

Then, the top of the baffle is separated from the bottom of the support plate, and the left side of the top of the support plate is pressed downward to compress the left support spring and stretch the right support spring, so that the support spring returns to its original position, so that the left support spring expands and the right support spring contracts, so that the right side of the support plate is pressed downward, the left support spring is stretched, the right support spring is compressed, and the support spring also returns to its original position, so that the left side of the support plate is pressed downward, so that the left end of the support plate swings up and down, causing the medicine bottle to shake.
