The Tegrapol-21 with Tegraforce-5 and Tegradoser-5 will polish up to 6 x 30mm resin mounts at a time. The various stages of grinding and polishing are carried out automatically by user-defined programs (the diamond cutting media is also automatically drip-fed onto the polishing plate). The resin mounts are prepared by mixing the sample with a two part resin. They are then placed in a vacuum chamber so as to impregnate the sample with resin and to remove any air bubbles. The mounts are then left to set (10-12 hours). Once polished the samples can be carbon coated for SEM/MLA analysis.
