ProductDescription : Function of colorimetric tubeThe colorimetric tube is the main instrument for visual colorimetric analysis experiments in chemical experiments, and can be used to roughly measure the concentration of solutions.
InstructionsStep 1. Use a burette to drop the standard solution into several colorimetric tubes (assuming that the colorimetric tube is of VmL specification, and the standard solution concentration is a), and the volume of the standard solution dropped into each colorimetric tube is different (assuming that X1, X2, X3...), and then add distilled water to each colorimetric tube with a dropper to the scale line, cover the stopper and shake well, so that each colorimetric tube can be dripped according to the standard solution and the burette. The volume of the standard solution in the tube calculates the concentration of the solution in each colorimetric tube (the solution concentration in each colorimetric tube is aX1/V, aX2/V, aX3/V...).
Step 2. At this time, put the solution to be tested into another colorimetric tube, and then compare the colorimetric tube containing the solution to be tested with the standard solution prepared before (colorimetry is to compare the colors), The concentration of the solution to be tested can be roughly obtained.
Step 3. During colorimetry, compare the colorimetric tube containing the solution to be tested with one colorimetric tube containing the standard solution at a time. When comparing, place the two colorimetric tubes in front of white paper with the same light level, and use the naked eye to compare the colorimetric tubes. Observe the color difference.
Precautions1. The colorimetric tube is not a test tube and cannot be heated, and the wall of the colorimetric tube is thin, so it should be handled with care;
2. The same colorimetric tube should be used in the same colorimetric experiment;
3. When cleaning the colorimetric tube, do not scrub with a stiff brush, so as not to damage the tube wall an
