Sirchie Coomassie Blue, 25g/0.88oz

The Sirchie LV512 Coomassie Blue (25g) enhances latent prints contaminated with blood on porous and non-porous surfaces, but will not develop a normal perspiration-based print. Application can be repeated until maximum contrast is achieved. It gathers physiological samples and conducts all fingerprint development methods prior to use. It is sensitive to proteins found in blood.
