The light avoiding flow colorimetric dish is a key equipment in the field of spectral analysis, whose core function is to achieve dynamic flow detection of liquids, while eliminating interference factors through structural optimization to improve detection accuracy. Light shielded flow colorimetric dishes are mainly used for real-time monitoring of the concentration or absorbance of liquid samples in laboratories, commonly used in biochemical analysis, spectral detection, and other scenarios. Real time measurement of parameters such as concentration and absorbance is achieved through the continuous flow of sample solution and the use of equipment such as spectrophotometers.
Based on the interaction between matter and light, when a sample or reagent flows in a flow colorimetric dish, the substance absorbs specific wavelengths of light energy and emits a longer wavelength fluorescence spectrum. By measuring the intensity and wavelength of the fluorescence spectrum, the type and concentration of the substance can be determined.
Usually made of quartz material, it has high transparency (especially in the ultraviolet region) and chemical stability, and is resistant to acid and alkali corrosion. Some models are designed with a light shielding structure to avoid external light interference with the detection results.
structural characteristics
Diverse materials: usually made of black quartz and transparent quartz, some also use aluminum and other metals as outer body materials, cavity materials, etc., with good chemical resistance, high temperature resistance, and optical transparency.
Light shielding design: The colorimetric dish has a light shielding shell on the outside, which can prevent external light from entering and avoid interference with the internal sample reaction caused by light. The light holes of some colorimetric dishes are well designed, such as in the shape of a "playground track", which can reduce the interference of bubbles on the light beam and ensure the stability of detection.
Flow channel: There is a pipeline inside for the flow of the test solution, with a spiral interface with a flow tube at the top, which can be connected to the flow analysis system, allowing samples or reagents to be pumped into the flow cell for mixing, reaction or detection.
Maintenance and Storage
After cleaning, air dry naturally or blow dry with nitrogen to avoid scratches caused by wiping.
When not in use for a long time, quartz/glass colorimetric dishes can be soaked in distilled water to prevent drying and cracking.
Regularly check whether there are scratches or stains on the transparent surface. If there are no scratches on the quartz colorimetric dish, it can be used for a long time (2-5 years), and it is recommended to replace the glass colorimetric dish after 1-2 years.
