This instrument is composed of ultraviolet lamp tube and filter. One can emit intense UV rays of 253.7 nm and 365.0 nm respectively, and can also mix the two wavelengths at one time.
 
The machine has the advantages of low power consumption, low heat, continuous use for a long time, and large zui, which can be turned on and off as soon as it is turned on, and can be used as soon as it is turned on. The light emitted by ultraviolet lamp tube is filtered out by a filter, thus providing intense ultraviolet light of 253.7 nm and 365.0 nm for fluorescence analysis.
 
Use
 
1. It is a necessary instrument for detecting many main substances such as proteins and nucleotides in scientific experiments.
 
2. In drug production and research, it can be used to check the quality of various drugs that can produce fluorescence, such as hormone alkaloids and vitamins. It is especially suitable for thin layer analysis, paper layer analysis spots and detection.
 
3. Determine various fluorescent materials, fluorescent indicators and additives in dye, paint, rubber, petroleum and other chemical industries, and identify different kinds of crude oil and rubber products.
 
4. It can be used to measure different kinds of raw materials such as wool, silk man-made fiber and cotton synthetic fiber in textile chemical fiber, and can check the quality of finished products.
 
5. It can be used to check the quality of toxins, food additives, deteriorated vegetables, fruits, cocoa fat, chocolate, fat, honey, sugar and eggs in the departments of grain, oil, vegetables and food.
 
6. In geology, archaeology and other departments, it can discover various minerals and judge the authenticity of cultural relics and fossils.
 
7. Finger mark determination and steganography can be checked at the door.
