Ball Pestles For Spectrovial® Comminution And Blending Vials
Ball pestles serve as the grinding media in conjunction with the use of SpectroVials® for comminuting powdered material substances in SpectroMill Ball Pestle Impact Grinders. The selection of a ball pestle material is a function of the type of SpectroVial in use.
Plastic methylmethacrylate ball pestles are intended to be used with plastic polystyrene SpectroVials. By comparison to metallic SpectroVials and their corresponding ball pestles, plastic is relatively soft and not very effective in the comminution process. Its principal application is for blending sample material substances or for comminuting soft samples.
Stainless steel metallic ball pestles are primarily used for comminuting relatively hard sample substances. Tungsten carbide ball pestles in combination with titanium carbide SpectroVials are much more effective grinding media for extremely hard samples.
The effectiveness of the comminution process to achieve an analytically acceptable particle size is a function of the initial sample charge, type of comminution vial and ball pestle materials, number of ball pestles and processing time. Empirical testing and evaluation is recommended to ascertain the best statistically reproducible x-ray analytical data.
