Ultraviolet Radiation (Optional) – 2.8
Ultraviolet Radiation (UV) lamps may be fitted as an optional extra; these can be fitted as new in
our factory or retrofitted at a later date on site. If installed the cabinet will have1 or 2 (Depending
on cabinet size) short wavelength Ultraviolet (UV) tubes emitting 254 nano metres fitted to the
inside work area of the safety cabinet.
As a safety feature the UV tubes are interlinked with the cabinet lights to prevent them being used
when the cabinet is in use.
Over time, the effective life of UV tubes is known to reduce; therefore we would recommend UV
tubes are replaced on an annual basis to ensure maximum efficiency.
Applications
Many bacteria are quite resistant to UV Radiation, and may require prolonged exposure for
sterilisation. Dry and/or protein covered organisms may be protected against UV and may be only
slightly affected if at all. However, moist, vegetative cells without too much protein covering are
killed with reasonable effectiveness after 3-4 hours exposure.
Warning
Extreme care must be exercised when using UV
radiation. Consult your Laboratory Safety Officer
prior to use.
UV Radiation can cause burns to unprotected skin
and it is very important not to look directly at the
illuminated tubes with the naked eye.
