This presentation sets out the results from a recent test comparing a dry heat sterilizer compared to a steam sterilizer for the laboratory animal cages, IVC racks, enrichment, and a selection of additional vivarium equipment. Robert Davis illustrates the data pertinent to today’s vivarium designers and operators, namely the relative cost and sustainability features. He provides use case studies detailing efficacy, load configuration, space and utility requirements, cycle parameters, and net cost calculations.
