For reprocessing of laboratory glassware

For more than four decades Miele Professional has set innovative milestones in the efficient and safe reprocessing of laboratory glassware. The machines from Miele Professional have set the benchmark for the centralized and decentralized reprocessing of large quantities of laboratory glassware with perfect added value: More cleaning power, more process safety and more efficiency.
System4Lab – everything from a single source
With System4Lab, Miele Professional offers a comprehensive system for the effective and economical reprocessing of laboratory glassware. Based on many years of experience and in close consultation with experts in the field, System4Lab covers all the major aspects of reprocessing: powerful appliances, perfectly integrated process chemicals, a nationwide customer service, and comprehensive advisory service by experts in our in-house application laboratory. Technology and know-how come from the same source and therefore are perfectly integrated with each other. The result is an analytically pure, particularly seamless, gentle, and economical reprocessing process. And administration time is also optimized, since in all aspects, from appliance technology to planning and financing, Miele is always at your side as a competent contact point.
Manual versus machine reprocessing
Any handling of laboratory glassware harbors a potential danger for laboratory personnel. Broken glass during manual cleaning can lead to dangerous injuries. Infectious and toxic contamination represent a health risk. The cleaning agents used are often very caustic.

Only the machine reprocessing of laboratory glassware and utensils can be standardized, validated, and automatically documented. Because the washers remain locked throughout the whole process and the whole process runs automatically, any potential danger for laboratory personnel is reduced to a minimum. In this way, maximum protection is achieved for personnel during machine reprocessing.
Water quality
Water quality plays an important role in the analytically pure reprocessing of laboratory glass. Domestic water contains salts and minerals which can result in deposits on the load and on machine surfaces. Fully demineralized water also prevents instrument corrosion. It makes sense to ensure the right water quality, especially with high water consumption levels. Systematic water treatment increases the efficiency of the washer-disinfector. Filtration protects from harmful deposits, avoids down time as well as repairs, and lowers the costs of detergents.
Application & laboratory glassware and utensils
The application can generally be categorized by the field (e.g., organic, inorganic chemistry, biology, etc.) and by the purpose or the work method (e.g., preparatory work, analyses, etc.). Frequently, the machine features, the flow of the cleaning process, and the choice of cleaning agents are decided based on the application.
The laboratory equipment should be recorded based on the type (e.g., beakers, round-bottom or graduated flasks, measuring cylinders, etc.), size or volume (e.g., 1 ml, 500 ml, etc.), and quantity of the laboratory machines. Based on this list, a detailed assessment regarding the required features of the washers can be made.
Contamination and disinfection
Knowledge of the physical and chemical characteristics of contamination in laboratory equipment is of particular significance for the cleaning processes and the choice of detergent.
The physical and chemical characteristics of the contamination include, for example, the water solubility under acid, pH-neutral or alkaline conditions, the chemical conversion through hydrolysis or oxidation, the melting or softening point, the possibility of emulsion, suspension or dispersion.

For certain applications, disinfection of the laboratory equipment is required. On the one hand, disinfection protects laboratory personnel who work with infectious contaminants. On the other hand, disinfection prevents the transfer of germs from samples and preparations in medical laboratories, hygiene institutes, pharmaceutical laboratories, the food and cosmetics industry.
Miele Service: Qualification of cleaning systems
In the pharmaceutical, food-processing, and cosmetics industries, all cleaning systems used in production, quality assurance, and R&D must be qualified. Qualification comprises:
Design Qualification (DQ), Installation Qualification (IQ), Operation Qualification (OQ), Performance Qualification (PQ), and, in some cases, process validation. The operator is responsible for the implementation of these measures. Support can be provided by Miele Service, who can take on some of the operator duties. To this effect, Miele offers the special service package “Installation Qualification and Operation Qualification” (IQ/OQ).
Before the IQ/OQ can be performed by Miele Technical Service, the required documents must be created, inspected and released for use by the operator. The Miele technician then completes the qualification based on these documents. All the necessary calibrated and certified test apparatus is provided by Miele.
Installation Qualification (IQ)
The aim of the Installation Qualification is to determine whether the cleaning system and its installation meets the requirements of the operator (Design Qualification) and the appliance manufacturer. During the IQ inspection, Miele service engineers document, measure, and assess compliance of delivered units with the original order, unit configuration and condition, installation and connection of the cleaning system, and the calibration of certain measuring systems.
Operation Qualification (OQ)
During the Operation Qualification, the inspection verifies whether the connected and installed cleaning system operates in accordance with the specifications of the operator and the appliance manufacturer.
The documentation, inspection, and evaluation of the OQ includes safety-relevant and operation-relevant functions, process-relevant notifications, as well as the program sequence.

Training of operating personnel is also completed and documented during the Operation Qualification. This rounds off a comprehensive package comprising IQ/OQ paperwork, the services of highly skilled and qualified service engineers, and the use of calibrated, certified test apparatus.
