1 bottle of fixative (200ml); 1 bottle of dye (200 ml); 1 bottle of clearing agent (200ml).

Working principle

The acidic fluorescein crystal sticks to the protein in the blood to produce yellow blood fingerprint. Expose the exhibit to blue light to produce yellow fluorescence.

Method

A. Fix the prints: to prevent the acidic fluorescein crystal from damaging the ridge details, before being dyed, the blood fingerprint should be dried or fixed with blood fixative.

B. Dye the prints: hold the dye spray and press the nozzle trigger to spray the dye on the entire surface of the exhibit.

C. Flush the prints: hold the clearing agent spray and press the nozzle trigger to spray the clearing agent on the exhibit. Remove the dye on the background of the exhibit until the print is fully developed.

D. View the fluorescence: dry the exhibit with hot air, irradiate the fingerprint with the 450nm light, view the exhibit through a barrier filter, and the fluorescent yellow fingerprint can be seen. Note: The fluorescence effect is not good when the exhibit is wet.

Put the filter paper on the fresh blood, spray the blood fixative to fix the blood
