No chemicals are involved and there is no risk of dangerous overdosing. Long process times are not required as sterilisation is instantaneous.\u003c\/p\u003e\n\u003cp\u003eThe highly concentrated UV-C energy exerts a lethal effect on living organisms. It alters the genetic material (DNA) and inhibits their reproduction capability. The germicidal properties of UV-C radiation are therefore extremely beneficial in destroying bacteria, viruses, protozoa, algae, yeasts and mould spores. Different pathogens require different radiation levels to be neutralised; intensity can be increased by reducing flow rate through the unit for greater contact time.\u003c\/p\u003e\n\u003cdiv\u003eTransmission Loss\u003c\/div\u003e\n\u003cp\u003eQuartz is 96–98% transparent to UV-C while normal glass reduces transmission by approximately 50%. Conventional sterilisers using a glass tube lose a significant portion of UV output before it leaves the lamp.
