Cleaning DURAN®
Special glass laboratory equipment can be soaked and washed by hand in the sink or washed by machine in a laboratory dishwasher. Laboratory dealers can supply a wide range of cleaners and cleaner-disinfectants. We recommend washing all laboratory glassware before it is used for the first time, since the possibility that it may have become contaminated in some way during transport can never be completely excluded. The best way to care for your glassware is to wash it as soon as possible after use at a low temperature, on a short cycle and at low alkalinity.
Cleaning by hand
The normal method is to wipe and rub the glass with a cloth or sponge soaked in a cleaning solution. Abrasive cleaners and abrasive sponges should not be used on laboratory glassware, as these can damage the surface of the glass. When soaking glassware it should be left as a rule in the cleaning solution for 20 to 30 minutes at room temperature, then rinsed with tap water followed by distilled water.
The soaking time should be increased and a higher temperature used only for stubborn marks. Laboratory glassware should not be soaked for long periods in alkaline media at more than 70°C since this can have an adverse effect on the printing.
Machine cleaning
Machine cleaning in a laboratory dishwasher is kinder to glassware than soaking it. The glass only comes into contact with the dishwashing liquid for relatively short periods when it is being sprayed onto the surface of the glass by the sprayer or injector jets.
