8.1 Grinding elements
NOTICE!
Cool grinding elements made of agate, sintered corundum,
zirconium oxide and silicon nitride slowly and carefully.
Do not heat agate elements in a microwave under any cir-
cumstances (heating is too fast).
They must never be exposed to thermal shocks as this
could cause irreparable damage to the parts ® They will
burst apart like in an explosion.
n Clean the grinding bowl and grinding balls each time after using
them: Clean them, e.g., under running water using a brush and a
commercially available cleaning agent.
n Roughly half fill the grinding bowl with grinding balls and a little sand
and water and run for 2 to 3 minutes (correctly tensioned) in the
Vario planetary mill.
n Cleaning with an ultrasonic cleaner is permitted.
n For sterilisation in the heat cabinet, only heat the grinding elements
up to 100 °C.
8.2 Mill
n The Vario planetary mill can be wiped down with a damp cloth after
it has been switched off.
