5 Care, cleaning and maintenance
Care
If used for its intended purpose, the laboratory hot plate does not need any special care.
To facilitate cleaning, it is advisable to:
avoid liquids boiling over!
•
avoid residues being burnt hard!
•
Cleaning
The glass-ceramic material is largely chemically resistant. The heating surface remains level at all times,
is free of pores and therefore easy to clean. If the heating surface is slightly soiled, the best way to clean it
is with hot water and a few drops of a mild household detergent when the heating surface is lukewarm or
cold.
To remove encrusted residues, lime and water marks, as well as stains with a metallic shimmer you
should use a household cleaning agent suitable for hobs with glass-ceramic heating surfaces. Use a wet
cloth or sponge to thoroughly remove any remaining cleaning agent, as some of the commercially
available cleaners can be corrosive at higher temperatures. If residues have already become encrusted,
remove them manually with a razor-blade scraper. Any plastic objects and aluminium foil as well as
substances containing sugar coming into contact with the hot surface must be removed immediately
with the scraper.
Maintenance
The laboratory hot plate does not require any maintenance if used for its intended purpose.
Before each use, first check the mains cable to ensure that it is in perfect condition. Do not use the
•
laboratory hot plate with a damaged cable!
CAUTION! Danger of electric shocks!
!
Do not use laboratory hot plate with damaged cables!
Never use abrasive cleaning agents! In most cases, it is sufficient to clean the
hot plate with a damp cloth and some mild household detergent after each
use. Then rub dry.
Any encrusted and boiled-over food should best be soaked first with a wet
cloth. Then remove the residues with a glass scraper.
Note:
Sugar and melted plastic should immediately be removed from the hot heating
surface.
