The Heavy Duty Digital Grinding Mill v2.0 is a solids sample accessory that offers high speed pulverizing action. Compared to older Wig-L-Bug Grinding Mill models, this new 2.0 version offers enhanced features including chemically resistant Stainless Steel construction and an integrated safety cover with a clear protective window to view the grinding vial operation. For added safety, the safety cover is interlocked with an emergency sensor which disengages operation in the open position.
The Heavy Duty Digital Grinding Mill v2.0 engineering also boasts “super quiet operation” with greater control over grinding speed and time intervals. The digital speed selected as revolutions per minute (rpm) can be 2500, 3000, 3600, 4000, 4200 or 4600 rpm. The digital time selected in seconds can be 5, 10, 15, 30, 45 or 60 seconds. Using the 1.70” long x 0.50” diameter Stainless Steel vial with a 1/4” Stainless Steel ball pestle, the rapid motion of the vial and the fast mixing action of the ball pestle permit samples to be ground more uniformly and reproducibly. The mixing action is reciprocating in the form of a figure eight. At 3000 rpm, the ball pestle swings through a 6.5 degree arc and strikes the ends of the vial 1875 times in ten seconds. The selected speed and duration of grinding influences the particle size. This productive device is a convenient replacement of conventional agate mortars and pestles.
Contributing to the Heavy Duty Grinding Mill v2.0 stability is the 12 pounds weight and size (6.30” height x 7” width x 11” depth). When ordering, specify 110V or 220V voltage.
