Purchase decisions rarely focus on the chamber size of the washer-disinfector. Of greater importance is the workflow resulting from the combination of all measures required to transform a contaminated, residue-coated instrument into a state suitable for use in patient treatment - cleaned, disinfected, packaged and ready-to-use. The most important criteria in this situation are: the duration of the operating times, the possibility of ergonomic loading and unloading, instrument drying and the overall level of ergonomy and economy. A large washer-disinfector is usually equipped with longer operating times and a larger chamber; this is associated with higher costs of consumption (energy, water, process agents).
What is the point of having a large washing chamber if it is not possible to load it in an appropriate time or if it is necessary to accumulate a sufficient number of instruments in order to ensure economical running. Storing contaminated instruments in a washer-disinfector for too long can adversely affect the decontamination process. The practice-optimized washing chamber of the MELAtherm was developed in co-operation with a number of its potential users. Sufficiently dimensioned to hold enough instruments to treat 40 patients, the chamber is small enough to minimize consumption and operating costs.
