UV cuvettes, infrared cuvettes, quartz cuvettes, glass cuvettes, precautions, cuvettes are generally rectangular, the bottom and sides are frosted glass, the other two sides are made of optical glass Made up. Therefore, you should pay attention to the following points when using:
1 When handling the cuvette, only touch the frosted glass on both sides with your fingers to avoid contact with the optical surface.
2 Do not touch the optical surface with hard objects or dirt. When the solution is contained, the height is 2/3 of the cuvette. If there is residual liquid on the optical surface, it can be gently absorbed by the filter paper and then wiped with lens paper or silk.
3 Solutions containing corrosive glass should not be stored in cuvettes for long periods of time.
4 The cuvette should be rinsed off immediately after use. Soak with 1:1 hydrochloric acid if necessary, then rinse with water.
5 Do not place the cuvette on a flame or electric stove for heating or drying in a dry box;
6 If the contrasting dish is suspected during the measurement, it can be tested by itself. The user can set the wavelength to the actual wavelength used, inject a set of cuvettes into distilled water, adjust the transmittance of one of them to 95% (100% of the digital display), and measure the other transmissions. Compared, the difference between the transmittances is not more than 0.5%.
