Place the micro-precision sieves in a thick-walled glass container
containing cleaning agent (e.g. water with tensides or
alcohol in a 5 litre beaker with walls about 3 mm thick).
• Immerse the sieve in the cleaning agent sieve foil side up.
• Place the beaker with sieve into the wire basket in the ultrasonic
bath.
• Before turning the ultrasonic bath ON, check the level of the
liquid in contains: it must be about 3 to 5 cm below the edge of
the bath to ensure good coupling of the ultrasonic energy.
• Rinse sieves with alcohol and let them air dry. Drying possible
at max. 40°C.
