Our 5-Sulfosalicylic Acid Blood Fixative is highly recommended for setting bloody prints or footwear impressions before performing enhancement techniques that utilize an aqueous-based formulation. This will prevent loss of detail of the impression that could be caused during enhancement.
Techniques that 5-Sulfosalicylic Acid Blood Fixative could be used with include, but are not limited to, our Acid Yellow 7 Latent Print Fluorescent Stain (Reorder No. CHE-1520) or our Acid Violet 17 Latent Print Fluorescent Stain (Reorder No. CHE-1526).
