Ball pestles serve as the grinding media in conjunction with the use of SpectroVial® grinding/blending vials for processing powdered material substances in SpectroMill® Ball Pestle Impact Grinders. The selection of a ball pestle material is a function of the type of vial.
• Spherical balls for use in all SpectroVials®
• Different materials (hardness) for differnet samples
• Typically match ball pestle material to SpectroVials® material
Ball pestles serve as the grinding media with the use of SpectroVial® Grinding and Blending Vials and the SpectroMill® Ball Pestle Impact Grinder and Mixer. The selection of a ball pestle material is related to the type of SpectroVial® material; they should be materialistically similar with respect to their hardness. The effectiveness of the grinding process to achieve an analytically acceptable particle size depends on the initial sample charge, grinding vial and ball pestle materials, number of ball pestles and processing time. Empirical testing and evaluation is urged to ascertain the best statistically reproducible analytical x-ray data.
