Laboratory Mill

Laboratory mills, used primarily for sample prep prior to analysis, use particle size reduction (comminution) to grind or homogenize wet, dry, hard, soft, elastic, brittle, and fibrous materials. Mills and grinders are used in labs in widely varying scientific areas, including chemistry, pharmaceuticals, food analysis, materials testing, and life science. Disk, hammer, mortar, planetary ball, rotor, and cutting mills are available to achieve coarse, mid-range, and fine results, all the way down to the nano range, <0.1 µm. Cryogenic mills, or freezer mills, are a type of unit that freezes a material prior to reducing its particle size.

What to consider when choosing a laboratory mill?

When purchasing a mill, power, speed, and cleanability are useful parameters; however, it is also important to keep in mind the instrument’s throughput, reproducibility, and yield, as well as the option of a cooling system, if necessary.
