Increased Safety During Evidence Processing

forensic evidence processing levels of protection

Cases are made or broken on evidence. That’s one reason why proper handling of seized evidence is essential. Properly handling and storing evidence helps protect it from cross-contamination, rendering it unusable. Yet the need for protection can go beyond the chain of custody. Laboratory analysts may require protection against certain particulates or biological materials during evidence processing. It is therefore essential to understand the best forensic laboratory equipment for your application and the best equipment for the protection level your work needs. Air Science® has made this easy by creating a visual guide to protection levels for forensic evidence processing equipment.

Purair® SafeSEARCH Ductless Fume Hood
The Purair SafeSEARCH uses activated carbon filtration to capture potentially harmful vapors used in the manufacture of drugs or to mask the odor of narcotics and HEPA filtration to capture airborne particles.
  Purair PCR Laminar Flow Cabinets
During evidence processing, PCR is used to amplify even minuscule amounts of biological evidence, so that laboratory analysts have enough DNA to create a profile. PCR laminar flow hoods help prevent cross-contamination that can adversely affect samples. They’re used to protect genetic evidence on the work surface where user protection is not required.
  Purair BIO Biological Safety Cabinet
The Purair BIO Biological Safety Cabinet (BSC) protects laboratory analysts, biological evidence and the forensic laboratory environment from potentially hazardous materials.


Air Science Forensic Products

In addition to selecting the right ductless equipment, forensic technicians should also use the correct personal protective equipment and utilize the right forensic evidence storage equipment. Safekeeper® Forensic Evidence Drying Cabinets are designed to store, dry or otherwise process forensic evidence using a controlled environment to maintain the chain of custody. Ductless technology removes airborne pathogens, particulates, fumes and odors emitted by the contents to ensure a safe work environment.

The Safekeeper® COLD is a unique refrigerator that provides temperature-controlled storage within a single cabinet. It offers multiple layers of security ideal for evidence that requires storage below room temperature to maintain integrity.

Our full line of forensic equipment ensures accurate, repeatable results from collection and transportation to storage and evidence processing.
