Rounded edge
No danger of injuring your fingers
Aka-Allegran has a rounded edge. Thus it is no longer dangerous to touch the egde like it still is on competing systems.
The magnetic discs surface stays clean and dry
The edge also makes sure the surface of the magnetic discs stays clean and dry, thus improving the lifespan of the magnetic discs. For a more in depth explanation please read further under Aka-Ronan.
Clean fingers
Perhaps the best feature, according to many users. Gone are the dirty fingers always associated with metallographic sample preparation.
Abraded material is always deposited at the edge of a preparation surface, where you get it on your fingers while changing the surface. The rounded edge of Aka-Allegran makes it possible to clean the edge, while the disc is still rotating. Keep a piece of paper towel pressed against the edge while the disc is rotating. The now clean Aka-Allegran can be lifted of, without getting dirty fingers.
