7.1 Grinding elements
n Clean the grinding cup and grinding bodies each time after using
them:
Clean them under running water, for example using a brush and a
commercially available cleaning agent.
n Half fill the grinding bowl with some sand (1/3 of the useful volume)
and water, and run for 2 to 3 minutes (correctly tensioned) in the
vibrating cup mill.
n Dry the grinding cup and grinding bodies well after the cleaning.
n For sterilisation in the heat cabinet, only heat up to 100 °C.
NOTICE!
Cool grinding elements made of agate slowly and carefully.
Do not heat agate elements in a microwave under any cir-
cumstances (heating is too fast).
They should never be exposed to thermal shocks as this
could cause irreparable damage to the parts ® They will
burst apart explosively.
7.2 Mill
After it has been switched off, the vibrating cup mill can be wiped down
with a damp cloth.
