Product features
Colorimeter tubes are the main instruments used in visual comparison experiments in chemical experiments and can be used to roughly measure the concentration of solutions. During color comparison, only compare the colorimetric tube containing the solution to be treated and the colorimetric tube containing the standard solution at a time. Place the two colorimetric tubes in front of white paper with the same illumination level, and observe the color difference with the naked eye.
There are precise graduation marks on the colorimetric tube to facilitate users to accurately read the volume of the solution. It is equipped with a frosted glass stopper, etc., which can be tightly plugged into the mouth of the tube, effectively preventing the liquid in the tube from evaporating, leaking, and external impurities entering the tube, ensures the accuracy of the experiment and the stability of the solution, especially suitable for long-term observation or storage. experiment.
The wall of the colorimeterc tube is thinner than that of ordinary test tubes, which makes it easier for light to penetrate the tube wall, makes it easier for users to observe the color changes of the solution in the tube and improves the accuracy of colorimetric analysis. When using colorimeter tubes for experiments, the steps are relatively simple. You only need to add the solution into the colorimeter tube and then perform color comparison. It is usually a flat-bottomed elongated tubular structure. This shape is convenient for hand-held operation and placement, takes up little space on the experimental bench, and is easy to observe the color change and liquid level of the solution in the tube. There is no complicated structure inside, makes it easier to clean.
The colorimeter tube has high transparency, smooth round bottom and no burrs; uniform wall thickness, smooth tube mouth, high transparency; round tube mouth, no leakage when poured; stable material, corrosion-resistant; glossy and transparent, fine craftsmanship, beautiful and textured ; The scale lines are accurate, clear and easy to read, and wear-resistant; the bottom of the tube is flat, stable and not easy to tilt; the frosting is fine, the bottle mouth and stopper are frosted, and the seal is consistent.

Product applications
Colorimeter tube are mainly used in the following areas:
In chemical analysis, it is used to measure the concentration of solution by visual colorimetry, and the content of the solution to be tested is determined by comparing the color with the standard solution.
It can be used to measure the content of specific substances in water, such as ammonia nitrogen, etc. during water quality testing.
In the field of pharmaceutical analysis, it is used to check the color of pharmaceutical solutions and detect impurity limits.
In chemical experiment teaching, it helps students understand the relationship between solution concentration and color and cultivate experimental operation abilities.
