Under the trusted brand of Tri-Tech Forensics, the Leucocrystal Violet Latent Print Aqueous Protein Stain with Fixative is a professional-grade solution specifically designed to enhance blood-stained fingerprints and footwear impressions in forensic investigations. This innovative product is a crucial tool in the field of forensics, offering a reliable and effective method for developing latent prints on a variety of surfaces, including fabrics, paper, and plastics.
The Leucocrystal Violet Aqueous Protein Stain, also known as LCV, is initially nearly colorless. However, when it interacts with hemoglobin in a bloodstain, it undergoes an oxidation process, transforming into a blue-colored solution that effectively stains the bloodstain. This unique feature allows for the clear visualization of blood-contaminated impressions, which are often critical pieces of evidence in criminal investigations.
The product comes with an included fixative, simplifying the application process into a single step. This ensures that bloody impressions are properly fixed before staining, preventing any loss of detail that could potentially compromise the investigation. To prepare the working LCV solution, simply combine the contents of the Part B and Part C vials with the Part A bottle and mix gently.
The most effective way to use this high-quality stain is by submerging the object in the solution. However, for objects that cannot be submerged, the stain can be applied by spraying it onto the item. The development process is quick, typically occurring within 30 seconds. To halt the staining action, the area can be carefully blotted with a tissue or paper towel.
For maximum contrast, the staining process can be repeated as needed. Any excessive staining of the background or other areas can be minimized by rinsing with clear water. After development, the item should be air-dried and photographed promptly to prevent any background staining caused by sunlight.
In conclusion, the Tri-Tech Forensics Leucocrystal Violet Latent Print Aqueous Protein Stain with Fixative is an indispensable tool for forensic professionals, offering a reliable, effective, and high-quality solution for the development of latent prints.
