BIOLOGICAL SAFETY CABINET WITH A FALLING-FILM EVAPORATOR

摘要

A method for decontaminating a biological safety cabinet with a falling film evaporator, the method comprising the steps of: providing a falling-film evaporator within a cavity of a biological safety cabinet, the evaporator having a housing defining a cavity and an evaporation element disposed in the cavity; conveying a liquid decontaminant from a source of liquid decontaminant to the evaporation element such that the liquid decontaminant flows along a surface of the evaporation element; conveying a carrier gas through the cavity of the housing wherein the carrier gas is conveyed along the surface of the evaporation element to evaporate the liquid decontaminant thereby forming a mixture of the carrier gas and the vaporized decontaminant; and exhausting the mixture into the cavity of the biological safety cabinet to decontaminate articles and surfaces in the cavity.
