Description
Blood Fixative – Essential Pre-Treatment for Forensic Enhancement
Our professional Blood Fixative provides a critical solution for preserving delicate biological evidence. Forensic investigators and laboratory technicians use this reagent to “set” blood-contaminated fingerprints or footwear impressions. Consequently, this step serves as a vital safeguard before you apply any aqueous-based enhancement techniques.
Preserving Critical Evidence Detail
You should always use a fixative before performing protein staining or chemical enhancement. Because many enhancement formulas are water-based, they can inadvertently wash away or smudge unfixed blood.
- Prevents Loss of Detail: The fixative stabilises the proteins within the blood. Therefore, it ensures the ridge detail or tread pattern remains intact during the staining process.
- Optimises Contrast: By securing the impression to the substrate, the fixative allows for a more aggressive application of dyes. This results in much sharper photographic evidence.
- Versatile Application: This product works effectively on both porous and non-porous surfaces. For instance, you can use it on wood, tile, or metal at a crime scene.
Quality and Shelf Life Standards
We supply this Blood Fixative as a made-to-order product. We follow this strict manufacturing process to ensure you receive the highest possible chemical activity.
- Maximised Shelf Life: Because we prepare each batch fresh, you get the longest possible utility for your laboratory or field kit. Please note that this item will expire 28 days after your order date.
- Professional Integrity: Using a fresh fixative prevents the chemical degradation that often occurs with mass-produced, off-the-shelf alternatives.
Safety and Laboratory Handling
While this fixative is essential for blood pattern analysis, you must handle it with extreme care. Always apply the solution in a well-ventilated area or under a fume hood. Furthermore, wear appropriate personal protective equipment (PPE) to avoid skin contact or inhalation. Once you have fixed the evidence, you can browse our full collection of chemical enhancement products here to find compatible stains like Amido Black or Hungarian Red.
