The Spectrum System 1000 is an 8-inch (200 mm), dual-design grinder/polisher ideal for the low- to medium-volume laboratory. It’s available as either a manual stand-alone base unit, or with an oscillating head for semi-automatic sample preparation. The powerful 0.5 HP (373W) motor drives both 8-inch wheels simultaneously. Adding the head assembly and an optional dispenser maximizes efficiency and throughput.
