A method is provided for maintaining the disinfection of medical equipment,in particular medical endoscopes (10), following processing. The method comprisesplacing the disinfected equipment (10) in a sealed chamber (12), and subsequentlyreducing the pressure within the sealed chamber (12) to cause evaporation ofresidual moisture. Gas scavenger sachets (21) are also provided within the sealedchamber (12) to remove atmospheric oxygen, thus causing a further reductionin the chamber pressure. The method may optionally include a further step of chargingthe sealed chamber (12) with a disinfectant gas or vapor. The processed medicalequipment (10) is then maintained at the desired level of disinfection withinthe controlled biostatic environment in the sealed chamber (12).
