Description
1,2-Indandione 99% 1 gram – Advanced Latent Print Developer
Our professional 1,2-Indandione 99% (1 gram) offers a high-sensitivity solution for developing latent fingerprints on porous surfaces. Forensic laboratories and crime scene investigators use this reagent to process paper evidence, such as letters, currency, and documents. Because 1,2-Indandione reacts specifically with amino acids, it provides an exceptional level of detail for forensic analysis.
Superior Sensitivity and Performance
Current research indicates that 1,2-Indandione works as well as, or often better than, DFO. Therefore, it serves as a primary choice for high-priority cases where maximum print recovery is essential.
- High-Fidelity Visualisation: You can easily visualise prints developed with 1,2-Indandione at 530nm. Consequently, using a forensic light source with filtration between 570nm and 590nm allows for clear, high-contrast photographic evidence.
- Enhanced Fluorescence: Similar to Ninhydrin, you can treat 1,2-Indandione prints with zinc chloride. This secondary process significantly increases the fluorescence of the ridge detail.
- Application Versatility: We supply this reagent as a high-purity (99%) powder in 1-gram units. This allows you to mix custom batches for dipping or spraying based on your laboratory requirements.
Professional Application Process
To achieve the best results, you must apply the solution to paper documents thoroughly. Once the evidence is saturated, you should allow it to dry completely.
- Thermal Activation: Like other amino acid reagents, 1,2-Indandione requires heat to react. You should process the treated papers in a forensic oven to trigger the fluorescent reaction.
- Clear Results: This method ensures you capture even the faintest latent prints. The resulting ridge detail stands out brightly against the substrate, providing a sharp image for fingerprint comparison.
Safety and Laboratory Standards
You should always perform this process in a controlled laboratory environment using a fume hood. Furthermore, wear appropriate personal protective equipment (PPE) to avoid inhalation or skin contact. We recommend storing the 99% pure powder in a cool, dark, and dry place to maintain its chemical integrity and ensure consistent performance across all forensic investigations.
