Scienceware® Micro-Mill® Grinders
Scienceware Micro-Mill® Grinders, with interchangeable grinding chambers, are perfect for rapid, high speed grinding of small samples from 20 to 50cc. A stainless steel or hard-faced blade rotates at speeds up to 12,000 rpm to successfully grind bauxite, bone, ceramics, coal, Devorda's alloy, fertilizer, filter paper, fly ash, frozen tissue, glass, grain, kaolinites, leaves, limestone, pharmaceuticals, pigment blends, plastics, rocks, roots, shale, seeds, slags, soil, teeth, wood, etc. To provide safety and prevent sample loss, the grinder operates only when the cover is latched in place.
The temperature is maintained by means of built-in heat exchangers, and the control panel has an overload protection reset button and a pilot light. Tubing connections 6.4mm (1/4”) on the cover and housing accept tubes for circulating water or slurry. Cover, grinding assembly and milling blade head are removable for cleaning. The stainless steel chamber is 54mm diam x 25mm deep (2 1/8 x 1”) inside an aluminum housing with an epoxy finish and non-skid rubber feet.
The 1/5 horsepower (150 Watts) motor develops a torque of 2.2 kg-cm (30 oz-inches) at 12.000 rpm. Supplied with a 1.8M (6ft) 3-wire cord and grounded plug. Overall dimensions are 14 L x 18 W x 28cm H (5 ½ x 7 x 11”). Shipping weight is 6.4kg (14 lbs).
