Cleaning of laboratory glassware

Special glass laboratory apparatus can be washed by hand in a soaking bath or by machine in a laboratory dishwasher. Laboratory dealers can supply a wide range of cleaners and cleaner-disinfectants for both methods. As contamination during the delivery of our laboratory glassware cannot be totally ruled out, we recommend washing laboratory glassware before it is used for the first time.

To care properly for laboratory glassware, it should be washed immediately after use at low temperature, on a short cycle and with low alkalinity.

Laboratory apparatus that has come into contact with infectious substances or microorganisms should be treated in accordance with the current guidelines. Dependent on the substance, autoclaving (e.g. to kill microorganisms) may be necessary prior to cleaning. It is generally recommended that cleaning or washing of glass products be carried out prior to autoclaving or hot-air sterilisation. This minimises dirt or impurities from adhering to the glassware surfaces and prevent damage caused by any possibly adhering chemicals.

Washer-disinfectors for automatic laboratory glassware reprocessing


Washer-disinfectors for automatic laboratory glassware preparation are available in various sizes and performance classes. You can find further information about automatic laboratory glassware reprocessing on the homepage of our cooperation partner Miele Professional.

60 cm wide compact machine. Performance/load: e.g. 37 narrow neck glasses, 96 pipettes


The product range extends from compact machines of 60 to 90 cm width up to powerful, large capacity machines. The large capacity machines are specially intended for central reprocessing of large quantities of laboratory glassware and are available as both 1-door and 2-door barrier machines for installation in a diaphragm wall.before purchasing a washer-disinfector, you must first be clear which laboratory glassware, and how much of it, requires reprocessing on a day-to-day basis within the laboratory. once the machine size is specified, the appropriate accessories can be individually selected. the accessories include trolleys and inserts for secure support of the laboratory glassware. Inserts are primarily for holding wide-necked laboratory glassware. special injector trolleys are offered to thoroughly clean laboratory glassware with a narrow internal diameter. these couple directly to the water supply of the machine and thus ensure that even internal cleaning of the laboratory glassware is correctly carried out. this system ensures that even difficult-to-access points are cleaned, which would be very difficult, or even impossible, to clean manually.





Nowadays, laboratory glassware preparation must constantly meet ever higher requirements in respect of performance and economy. Machine-based reprocessing is by comparison with manual cleaning, much more efficient: for example, the economy arises from lower time / personnel expenses, shorter process cycles as well as lower power and water consumption. In particular, the short process cycles mean the laboratory glassware is quickly ready for its next use. Minimal handling of contaminated laboratory glassware simultaneously reduces the potential risk to personnel (injury, chemical burns and risk of infection).


Value retention through gentle preparation


Automatic laboratory glassware preparation is gentler than manual cleaning. The glass surfaces only comes into contact with the alkalinity of the detergent for a short, defined time interval, so that glass corrosion is minimized. The accessories include special holders and locks so that the laboratory glassware is securely fastened and protected against breakage.
