The PCR Workstation provides effective decontamination of solutions, reagents and equipment before carrying out sensitive PCR reactions, particularly when amplifying DNA fragments which are either in limited supply or low copy number. Four timer-controlled 15 W UV bulbs enable the user to control the exposure time and dose of high energy UV irradiation required to denature nucleic acids preventing background contamination. Safety interlocks switch-off the UV bulbs automatically when the cabinet side doors are opened, preventing accidental exposure to the UV source. The cabinets construction from UV impermeable 10 mm acrylic also serves as an effective barrier against some radioactive isotopes, allowing the user to work in increased safety with ß- emitters such as 32P
and 35S. A single white light bulb illuminates the work area when the cabinet is in use.
