product key technologies
The WFH-203B Dark Box 3-Function UV Analyzer uses a fully enclosed, light-tight structure to eliminate external light interference, enabling high-contrast fluorescence observation without a darkroom. It is engineered for sensitive detection tasks requiring high clarity and accuracy. Equipped with professional quartz UV tubes and optimized filters, it provides stable 254nm and 365nm ultraviolet output. The sealed dark chamber enhances sample contrast, ensuring clear imaging for trace substance analysis and precise experimental recording.
Application
This dark box analyzer is widely used in high-sensitivity scientific research for detecting low-abundance proteins and nucleotides.
In pharmaceutical analysis, it provides clear visualization of fluorescent drug components.
It supports qualitative analysis in chemical industries, including dyes, coatings, rubber, and petroleum products.
It inspects textile materials and finished products, detects food contaminants and toxins, and performs high-clarity forensic identification and evidence analysis.
Instrument Structure
The instrument features a sealed dark chamber with 254nm and 365nm UV lamps and dedicated filters. An internal fluorescent lamp supports sample positioning. The anti-UV observation window ensures safe operation. The structure is stable, durable, and easy to maintain.

Note
1. The UV filter shall not rub against metal objects or bear external force. Keep its surface dry and clean, and wipe it thoroughly with clean gauze after each use.
2. Operators must wear protective goggles to protect eyes during operation.
3. Aim the UV light only at the sample. Avoid exposing any part of the human body to ultraviolet radiation.
Maintenance Method
1. Place the instrument in a cool, dry, dust-free area away from acid, alkali and steam. Keep the surrounding environment clean. Unplug the power cord and cover with the protective shield if the instrument will not be used for a long time.
2. Do not splash water or any liquid onto the instrument.
3. If the observation glass on the lamp box gets dirty, clean it with alcohol cotton balls.
