I. Overview:

ZF-8 type four-purpose ultraviolet analyzer (dark box type) is one of the newly developed ultraviolet instrument series, which can emit short-wave, medium-wave, long-wave ultraviolet and visible light at four wavelengths. The ultraviolet light emitted by this instrument has high intensity and good stability. The dark box has a protective effect and is widely used in molecular biology, chemistry, and forensic identification.

1. In biochemistry and medicine, DNA and RNA electrophoresis gel samples can be observed and analyzed to detect proteins and ribonucleotides.

2. In the pharmaceutical industry, it can be used to check the quality of drugs such as hormone alkaloids, vitamins, etc. that can produce fluorescence, and is particularly suitable for thin layer analysis, paper layer analysis and detection.

3. In the chemical and dye industries, different types of crude oil and rubber products can be identified, and various fluorescent materials, fluorescent indicators, additives, etc. can be determined.

4. In the textile industry, it can be used to identify cotton, synthetic fibers, silk man-made fibers, wool and other primitives.
