Bottle-Top Dispenser Cleaning Method

1.Manual or automatic cleaning Glass and plastic laboratory equipment can be cleaned manually using soaking or using laboratory cleaning equipment. Laboratory equipment should be cleaned immediately after use – a weak alkaline detergent can be used for simple soaking at low temperatures. Appliances that come into contact with infectious materials should be autoclaved as needed after cleaning. This is a method of preventing the sticking of chemicals so that the adhesion of chemical residues damages the bottle-top dispenser of the test apparatus.

Note: Be careful to disinfect the test equipment carefully before cleaning, if there is a risk of injury during the cleaning process.

2.Gentle washing For gentle handling of the bottle-top dispenser, it should be cleaned immediately after use — using low temperature, short soaking times and weakly alkaline detergents. Glass volumetric devices should not be soaked in alkaline solutions above 70 °C for extended periods of time as this can result in volume changes and scale damage due to glass erosion.

3.Useful information At 70 °C, 1N NaOH will erode approximately 0.14 μm glass for 1 hour. At 100 °C, this value becomes 1.4 μm, which is a tenfold increase. Therefore cleaning above 70 °C should be avoided and weak alkaline detergents should be used as much as possible.
