The Buehler(r) APEX(tm) System is a series of engineered products that offer practical laboratory solutions for specimen grinding, surface holding and storage. The Apex(tm) Diamond Grinding Discs are a series of abrasive surfaces that excel at planar and subsequent grinding steps for most materials. Combined with the Apex(tm) Hercules H&S, these discs produce high material removal and good specimen flatness. The Apex(tm) M&B Magnetic System magnetically attaches cloths and grinding surfaces to a platen while minimizing environmental waste.
