Forensic Applications
Protect the chain of custody from crime scene to crime lab.
When conducting DNA sampling using Polymerase Chain Reaction (PCR) machines to compare recovered DNA evidence to a suspect or victim’s profile, it is essential to prevent cross contamination. Yet PCR is extremely susceptible to contamination as it cannot distinguish DNA from different sources. To improve accuracy and reduce cross-contamination risks, thermocyclers or PCR machines should be operated in a PCR hood per CDC recommendations when analyzing DNA evidence.
When collecting evidence from the scene, portable glove bags like the Purair® Flex, help provide the necessary working volume while ensuring optimal safety measure. Mobile evidence transporters help to securely transport evidence from the field to the lab while allowing effective air-drying necessary for some evidence prior to processing.
Mobile evidence drying cabinets are designed to preserve the chain of custody and enhance the reliability and safety of biological evidence handling. Our SafeKEEPER® Forensic Evidence Drying Cabinet dries sensitive biological evidence like blood and bodily fluids for more effective storage. This helps preserve the integrity of the evidence, preventing contamination, and ensuring that it can be analyzed accurately later. The tamper-resistant chamber provides security to help maintain the chain of custody.
For the storage of illegal or suspicious substances, the DrugKEEPER™ Storage Cabinet provides short-term storage of hazardous chemicals and substances associated with drug investigations, helping to keep your laboratory or law enforcement offices safe.
We offer a wide range of forensic laboratory equipment for the development of fingerprints.
Fingerprint Powder Workstations
Our DWS Powder Workstations are ductless fume hoods designed to protect the user and the environment from hazardous particles generated from print analysis. Unrestricted front and side access permits intensive operator involvement, while downward airflow in the chamber protects the operator.
Latent Fingerprint Development
The SafeFUME™ and SafeFUME 360 use ethyl cyanoacrylate (CNA) vapor to develop latent fingerprints from non-porous surfaces.
SafeDEVELOP™ fingerprint development chambers are designed to safely develop latent fingerprints on porous surfaces using DFO, Ninhydrin, and other chemicals in a controlled environment.
3D printing processes generate fumes and particulates that pose potential health risks if not properly managed. As 3D printing technology continues to find its way in forensic sciences there is a need to create good practice for 3D printing processes and also ensure the continued safety of operators. Ducted fume hoods are ideal for high-volume 3D printing operations. They efficiently expel fumes and particulates through a ductwork system that vents directly to the outside environment.
Mold growth on organic matter can help investigators determine postmortem intervals more accurately. However, cross-contamination of forensic mycology samples can lead to failure and make or break a case. One of the best ways to protect evidence and other samples from contamination is to use a Mycology Hood, which creates a sterile environment on the work surface.
