Germicide UV Lamps

Germicidal lamps are also referred to as ‘bactericidal lamps’ or UVC lamps.  They are commonly used for sterilization as they are strong emitters of UVB and UVC radiation within the range 250-265 nm.  This wavelength is most effective for sterilization and disinfection since it corresponds to a maximum in the DNA absorption spectrum.

A common source of the UVR are low pressure mercury discharge tubes, since more than 90 percent of the radiated energy lies at the 254 nm line. 

Their main use is in hospitals and inside microbiological safety cabinets to inactivate airborne and surface microorganisms.  They are usually installed so that people are not directly exposed and eye protection is needed whilst the lamps are operating.  IF used correctly there is minimal risk of exposure, but they are capable of producing serious exposure to UVR at close range.
