Miele’s team of...

Manual v. machine-based reprocessing Many laboratories have deliberately chosen to wash their laboratory glassware, e.g. beakers, pipettes, volumetrics and flasks, Erlenmeyer flasks, Petri dishes and test tubes, in a machine-based process. One reason for this is to avoid the risk of exposure to hazardous substances. Broken glass from manual cleaning, for instance, can cause dangerous injuries. Infectious and toxic contaminants pose a health hazard. Cleaning agents used often contain substances that are highly irritant. Automatic, machine-based processes are also more easily standardised,...

3. Contamination An intimate knowledge of the physical and chemical attributes of the contaminants the machine will need to deal with is of particular importance in choosing the most appropriate cleaning process and detergents. The physical and chemical properties of a contaminant include, for instance, its solubility in water in acidic, pH-neutral and alkaline conditions, the efficacy of hydrolysis or oxidation, melting and softening points, its ability to emulsify as well as a substance’s suspension or dispersing properties. 4. Disinfection For certain applications laboratory glassware...

The G 7825/G 7826 series was designed with the requirements of larger laboratories in mind. With a width of only 900 mm, these machines are the ideal proposition in cases where space is at a premium. Depending on the installation site and hygiene requirements, machines are available as single-door front-loading models (G 7825) or as two-door barrier machines (G 7826) for installation in a diaphragm wall. Flexible solutions for the central and decentral reprocessing of laboratory glassware Miele’s G 7825 and G 7826 washer-disinfectors offer a wide range of installation options, tailored...
