1) Reference for the use of PP colorimetric tubes:
Use a burette to drop the standard solution into several colorimetric tubes (assuming that the colorimetric tubes are VmL and the concentration of the standard solution is a), and the volume of the standard solution dropped into each colorimetric tube is different (assumed to be X1, X2 , Display the concentration of the solution in each colorimetric tube (the concentration of the solution in each colorimetric tube is aX1/V, aX2/V, aX3/V respectively). 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), and you can roughly Find the concentration of the solution to be tested.
(2) Main features and key points:
1. The colorimetric tube is not a test tube and cannot be heated, and the wall of the colorimetric tube is thin, so handle it with care;
2. Colorimetric tubes of the same specification should be used in the same colorimetric experiment;
3. When cleaning the colorimetric tube, do not use a hard-bristled brush to avoid scratching the tube wall and affecting the light transmittance; thus affecting the use effect;
4. When comparing colors, only use two colorimetric tubes for comparison at a time and the lighting conditions must be the same;
5. High transparency, the inner volume of the tube can be seen with the naked eye; compared with glass colorimetric tubes, its advantages are resistance to falling and long service life;
6. The liquid pours out smoothly from the mouth of the cup, and the liquid will not drip down along the pouring mouth;
7. Resistant to acids, alkalis, alcohols, and alcohol chemicals;
8. Temperature resistance up to about 105ºC
9. It is mostly used in colorimetric experiments in various chemical analysis laboratories such as Centers for Disease Control and Prevention, geology and minerals;
