Colorimetric tube
Colorimetric tube: During colorimetric comparison, only compare the colorimetric tube containing the solution to be measured with one colorimetric tube containing the standard solution. When comparing, place the two colorimetric tubes under the same light level. Observe the color difference with the naked eye in front of the white paper.
Instructions for use:
Use a buret to drop the standard solution into several colorimetric tubes (assuming that the colorimetric tubes are sized and the concentration of the standard solution is) and the volume of the standard solution dropped into each colorimetric tube is Different (assumed to be,,...) Then use a dropper to add distilled water to each colorimetric tube to the scale line, cover the stopper, shake and shake well. This way, you can drip into each colorimetric tube according to the standard solution and the buret. Calculate the concentration of the solution in each colorimetric tube from the volume of the standard solution (the concentration of the solution in each colorimetric tube is /, /, /...). At this time, put the solution to be tested into another colorimetric tube and then compare the color of the colorimetric tube containing the solution to be tested with the previously prepared standard solution (colorimetry is to compare the colors) to roughly draw the conclusion The concentration of the solution to be measured.
Notes:
. The colorimetric tube is not a test tube and cannot be heated, and the colorimetric tube has a thin wall and should be handled with care
. Colorimetric tubes of the same specifications must be used in the same colorimetric experiment.
When cleaning the colorimetric tube, do not use a hard brush to avoid abrading the tube wall and affecting the light transmittance
When comparing the colorimetric tubes, only take two colorimetric tubes at a time for comparison and the lighting conditions must be the same.
