ADAPTABLE USABILITY
Bloody impressions are frequently found at the scene of violent crimes. These impressions provide valuable evidence and often help crime scene investigators identify suspects. Many items at a crime scene are fixed or too large to be brought back to the crime lab for analysis. This creates limitations on many departments and means numerous impressions are simply photographed with inadequate clarity and not fully analyzed in the laboratory. ZAR-PRO™ Fluorescent Blood Lifting Strips provide investigators with a safe, non-toxic fluorogenic method for lifting bloody impression evidence and can be standardized for use with substrates of all porosities, regardless of background pattern or color. These lifting strips are simple to use and are affordable for all law enforcement agencies regardless of budget.

YOUR TIME IS IMPORTANT
The entire process is quick and easy. You activate the lifting strip with ZAR-PRO™ Activator Solution and then lift the bloody impression for analysis. This process can be completed in just seconds.
     
SUPERIOR RESULTS
The fluorogenic property of the lifting strip does not require enhancement chemicals. These fluorescent properties are attributed to metal-enhanced fluorescence. Bloody and other proteinaceous secretions contain fluorophores, which cause the strips to fluoresce when visualized with an ALS or forensic laser. Lifted impressions are considered permanent and suitable for long term storage.
