The UV-Cleaner ensures DNA fragment-free laboratories without the use of direct UV irradiation. The ambient air circulates continuously through the unit by means of a fan, which is equipped with a high-energy UV lamp and a dust filter. Inside the UV box, the intensity of the UV light is amplified 1000-fold and is thus sufficient to completely inactivate DNA. Microbiological contamination is also greatly reduced. The UV-Cleaner has a flow capacity of 14 m3 air / hr.
