Desinfection tubs are required for cleaning and disinfection during manual processing and, if required, as preparation for automated processing of instruments as well as rigid and flexible endoscopes. The disinfection tub has a removable basket insert, a marker indicating the level of solution, a closely fitting white lid and comes in a number of different sizes. All disinfection tubs can be processed automatically. The basket insert enables easy removal of instruments from the cleaning or disinfectant solution. After removing the basket insert from the disinfection tub they can immediately be rinsed under running water. The tightly sealing lid prevents any contamination of the room´s air by volatile ingredients.
