product key technologies
The benchtop 3-function UV analyzer combines stable performance with lightweight design, featuring a durable plastic casing that reduces weight while maintaining structural rigidity. It is specially developed for teaching labs, routine testing, and small-scale research environments. The instrument uses high-performance quartz UV tubes and precision filters to provide stable 254nm and 365nm ultraviolet radiation. It supports flexible wavelength control and offers smooth, low-noise operation for daily analytical tasks.
Application
1. This benchtop 3-function UV analyzer is widely used in scientific research for protein and nucleotide detection.
2. In pharmaceutical development, it evaluates fluorescent drugs and supports thin-layer and paper chromatography.
3. In chemical industries, it identifies fluorescent materials, additives, dyes, coatings, rubber, and petroleum products.
4. It inspects textile fibers and finished products, detects food toxins and additives, and assists forensic identification in public security laboratories.
Structure
The device integrates dual-wavelength UV lamp assemblies and matched filters. A built-in auxiliary lamp supports sample preparation and positioning. The plastic casing provides corrosion resistance and light weight, with a simple structure for easy operation and minimal maintenance.
Advantage
1. Adjustable lamp holder: according to customer demand, adjust at will.
2. Dot matrix positioning: the seat is equipped with a fluorescent lamp, for the layer folding plate sampling, positioning lighting.
3. Dual-wavelength ultraviolet (254nm, 365nm).
4. Sealing design: strict design of the black box, so that the internal interference from external light.
5. Simple design: the bottom panel concave design, can effectively prevent the panel scratches.

Operation Skill
Pretreatment of Samples
Before detection, appropriate treatment should be carried out according to the characteristics of the sample. Solid samples should be ground evenly, and liquid samples should be filtered or diluted to avoid suspension interference. Biological samples may require special pretreatment to enhance the UV response signal.
Optimize the Observation Angle
Portable UV analyzers are usually equipped with dual-wavelength UV lamps. The appropriate wavelength should be selected according to the fluorescence characteristics of the target substance, and the observation angle should be adjusted to obtain better fluorescence effect. Slightly tilting the sample or changing the angle of the light source can sometimes improve the signal contrast.
Controlling Ambient Light Interference
Although the influence of ambient light has been considered in equipment design, it still needs to be paid attention to in strong light environment. Try to operate in a darker background or at night, or use a matching hood to avoid ambient light masking weak fluorescence signals.
Comparative Observation Method
For the detection of trace substances, it is recommended to use a comparative observation method: simultaneously detect the known standard and the sample to be tested, and determine the content of the target substance by the relative fluorescence intensity difference to improve the reliability of the results.
