Saphir 350 Grinder / Polisher 10-12in

ATM GmbH

The single wheel Saphir 350 Manual Grinding and Polishing System is built tough for high-volume specimen throughput using 250 mm (10") or 300 mm (12") wheel formats. High torque, variable speed motors are controlled by a sealed, touch button control panel. Because the wheel is recessed below the solid aluminum chassis, the Saphir 350 reduces abrasive splatter.

The Saphir 350 can be built either as a floor standing laboratory polishing table using SystemLab cabinets or as a table top version.

Topas M Automatic Dosing System

Topas M Automatic Dosing System

ATM GmbH

The Topas M provides an automatic dosing solution for all manual grinders & polishers. A weighted dosing arm can be placed anywhere around the polishing bowl to control where the suspension hits the grinding/polishing media. Four 500 ml glass bottles can be filled through a separate lid, even during operation, and are quickly removed for easy cleaning. A backflushing function keeps the hoses clean. When used in combination with the Saphir M series grinder/polishers the Topas dosing start/stop is controlled by the grinder/polisher (all other settings are programmed on the Topas directly).
