Using Ultraviolet Light to Eliminate DNA Cross Contamination

Air Science Logo

The Air Science UV-Box™ is a high-efficiency chamber designed to safely decontaminate contents while providing a safe work environment for the operator. High intensity UV lamps positioned within the cabinet produce short wave ultraviolet light at 254 nm to destroy exposed surface DNA and bacteria, leaving evidence free of contamination prior to other forensic tests, analyses or procedures.


UV lamps are optimally placed throughout the UV-Box to eliminate blind spots and ensure that all surfaces of equipment being decontaminated come into direct contact with UV light. The corners and walls of the box are smooth to make cleaning easy. Stainless steel surfaces naturally reflect UV radiation to ensure surfaces are fully irradiated from all directions. Additional design and construction features offer convenience and protect personnel during use, cleaning and maintenance of the cabinets.

The operator is protected from UV exposure by the UV absorbing window and safety controls which ensure lamps cannot be activated until the cabinet door is securely closed. Other features include a UV timer, hanging rod and shelf to support or suspend items for decontamination.

The UV-Box has been independently tested and validated based on strict regulatory requirements to meet the needs of forensic laboratories and ensure laboratory methods can legally stand in court cases.

DNA Decontamination in Forensic Science

Forensic scientists have long known that even minimal contamination from outside DNA sources can lead to erroneous results from highly sensitive polymerase chain reaction (PCR) experiments. Several main methods of DNA decontamination have been developed over the years, including ultraviolet (UV) light decontamination.
