The label of the reagent bottle should be written like this
The reagent bottle label is used to mark the name and characteristics of the solution, and its importance is beyond doubt. According to different uses, chemical reagents are divided into standard solutions and general solutions, and the labeling methods for different solutions are also different. So, how should the label of the reagent bottle be written?
The standard solution refers to the reagent solution with an accurate known concentration. The preparation, calibration, calibration and dilution of the standard solution should be kept in detail and should meet the same requirements as the original test record. The label of the reagent bottle should be complete, with clear writing and accurate symbols. The written content of the standard solution label includes the standard solution name, concentration type, concentration value, medium, preparation date, preparation temperature, bottle number, inspection cycle and preparation person, precautions and other matters needing attention.
Generally, the solution does not need calibration or other comparison methods to obtain its accurate concentration. In the test work, its concentration and dosage do not participate in the calculation of the content of the tested component, and are usually used as a “conditional” solution, such as controlling acidity, indicating the end point, eliminating interference, color development, complexing, etc. According to the application, it can be divided into developing solution, masking agent solution, buffer solution, extracting solution, absorption solution, alkali solution, indicator solution, precipitant solution, blank solution, etc. The label of the reagent bottle of the general solution should include the name, concentration, purity, medium, date, preparer and other instructions.
The label of the reagent bottle can identify the substance in the bottle, which helps the experiment to be completed better, and at the same time can protect the personal safety of the user.
