With Interchangeable Grinding Chambers

• Rapid pulverization of small samples from 20cc to 50cc
• Ideal for processing minerals, pharmaceuticals, pigment blends and other solid samples
• Built in safety switching avoids inadvertent operation unless fully assembled
• Cover, milling blade and grinding chamber are detachable for thorough cleaning

The grinders have a stainless steel or optional hard-faced blade rotating at up to 12,000rpm to rapidly grind a wide variety of material including bauxite, bone, ceramics, coal, Devorda's alloy and wood. Interchangeable grinding chambers reduce cross contamination. Each chamber is 54mm x 25mm (2 1/8" x 1")ID. The 1/5 horsepower (150 Watts) motor develops a torque of 2.2kg-cm (30 oz-inches) to maintain blade speed. The aluminum housing with epoxy finish is corrosion resistant and easy to clean. Built-in heat exchangers help maintain sample temperature. Included tubing connections, 6.4mm (1/4"), on the top and housing can circulate water, methanol/dry ice slurry or liquid nitrogen for more aggressive sample cooling. A resetable circuit breaker protects the motor and circuitry against damage from a jammed blade. Non-skid rubber feet protect the bench top. Power supplied through a 1.8m (6 ft) 3-wire cord with grounded plug. Dimensions: 14cm x 18cm x 28cm H (5 ½" x 7" x 11"H) Shipping weight: 6.4kg (14lbs)
