Amplification of DNA through the polymerase chain reaction (PCR) is a highly sensitive method capable of copying millions of DNA molecules from just a single molecule. Because of the extreme sensitivity of this method, any carry-over product from previous reactions can result in false positives or extra bands. Carry-over contamination can be avoided by using appropriate protocols and equipment. Among them, exposure to UV light (300 to 400 nm) within an enclosed area is recommended.
The Aura PCR is a very easy to operate cabinet specifically designed for this application. When the normal working procedures have been completed, the tempered glass front panel is closed and timer is activated in order to expose all internal surfaces and tools to UV radiation for a preset period of time. The 6 mm tempered glass body of the Aura PCR cabinet, acting as a filter to UV radiations, is safely protecting the external environment from dangerous exposure of personnel to those radiations.
