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.
