Description
This general purpose methanolic silver nitrate solution has a convenient spray head for application in the field or laboratory. The surface being treated should be sprayed lightly and evenly. After treatment, allow the article to dry completely, preferably in the dark (approx. 2 minutes). Then, illuminate with high-intensity light (sunlight) or No. SNA4 Silver Nitrate Accelerator Lamp. Fingerprints will appear as dark grayish-brown images and should be photographed before the article background develops.
