Product Overview

Acid Yellow 7 is a highly effective fluorescent dye specifically formulated for the enhancement and visualization of bloodstain patterns, particularly on porous or absorbent surfaces such as fabric, paper, and unsealed wood. It is an essential tool in the forensic toolkit, enabling investigators to uncover critical blood evidence that might be overlooked under standard lighting conditions.

When illuminated with a forensic light source between 415nm and 485nm, Acid Yellow 7 emits a bright yellow fluorescence, dramatically increasing the contrast and visibility of bloodstains—especially against dark, multicolored, or patterned backgrounds. This superior fluorescence not only aids in crime scene interpretation but also supports precise photographic documentation and court-admissible reporting.

Acid Yellow 7 is ideal for use in crime scene investigations, blood pattern analysis, and laboratory confirmation, revealing subtle stains and spatter patterns that may be invisible to the naked eye.

Key Features:

• Enhances bloodstain patterns on porous surfaces such as fabrics and paper
• Produces bright yellow fluorescence under light sources in the 415–485nm range
• Provides high contrast on dark, patterned, or complex backgrounds
• Ideal for crime scene analysis, documentation, and forensic photography
• Enhances detection of trace blood evidence not visible under ambient light

With Acid Yellow 7, forensic professionals can ensure thorough, accurate, and visually enhanced bloodstain detection, supporting deeper insight into crime scene dynamics and evidence interpretation.
