These instruments incorporate a germicidal ultra-violet lamp which rapidly destroys every micro-organism hit by its rays. Recommended to keep the instruments stored inside sterile. Instruments previously sterilized can be preserved for a long time and they are always ready for use (UV treatments do not generate heat). An inside supporting grate keeps instruments raised from refl ecting surface which enables both surfaces to be uniformly irradiated, improving the UV germicidal action. Operator safety is guaranteed by a micro switch which extinguishes the lamp if door is opened. Solid construction, painted steel outside and reflecting stainless steel inside.
