Retsch, Inc.: Rapid Mortar Mill
November 15, 2001
Retsch, Inc. recently launched its Rapid Mortar Mill MS 100 for precise X-ray fluorescence or other spectral analyses requiring accurate sample preparation. The MS 100 homogenizes small sample volumes (2-24 ml) to a particle size <120 microns, enabling the samples to be pelletized for subsequent analysis. Due to the high speed differential between mortar (30 rpm maximum) and pestle (3000 rpm maxium), the required fineness is typically achieved in 3-5 minutes. The reproducibility of all relevant parameters is guaranteed by digital speed control settings for mortar and pestle, memory function for three speed/time combinations, and scales in mm-increments for the pestle pressure and clearance.
