Service
The laboratory agitator does not require any special care when used as directed.
For ease of cleaning note the following:
•
Avoid overboiling!
•
Avoid dirt from sticking!
•
Cleaning
The glass ceramic is substantially chemically resistant. The heating surface remains always flat, is non-
porous and therefore easy to clean. The slightly soiled heating surface is best cleaned with warm water
and a few drops of dishwashing liquid, when the heating surface is warm or cold.
Crusts, lime and water stains, but also dazzling metallic stains must be removed with common household
cleaning agents for ovens with glass - ceramic heating surfaces. Please remove any remaining detergent
thoroughly with a damp cloth or sponge, as some cleaning agents on the market are caustic at an elevat-
ed temperature. If contaminants have already formed crusts, you should use a razor blade scraper.
Plas-
tic objects
and
aluminium foil
as well as
sugar-containing substances
, that come in contact with the
hot surface
must be picked up
immediately
with the scraper.

Prior to use, check the power cable for a perfect appearance. Do not operate the laboratory hotplate
with a damaged cable!
!
CAUTION! Risk of electric shock!
Do not operate the laboratory hotplate with damaged cables!
Do not use abrasive cleaning agents! Usually, it is sufficient to clean after
each use by using a damp cloth and household detergent. Then wipe dry.
Crusts are best soaked by using a wet cloth first. Then remove the rest with a
glass scraper.
Note:
Remove sugar and molten plastic immediately while the hotplate is hot.
