Stainless Steel Grinding Ball 05.368.0063, Ø10 mm – For CryoMill, MM 200 and MM 400
The Ø10 mm stainless steel grinding ball, reference 05.368.0063, is designed for use in Retsch vibratory mills such as the CryoMill, MM 200 and MM 400. It plays a central role in sample preparation processes in medical, pharmaceutical, biological and analytical laboratories. Thanks to its mechanical properties and compatibility with several stainless steel bowl formats, it enables homogeneous, reproducible grinding that meets the precision requirements of experimental or quality control protocols.
This model is used for particle size reduction of a wide variety of matrices, such as animal or plant tissue, pharmaceutical tablets, hair and even bones. It is used in dry, wet or cryogenic grinding phases, depending on the constraints related to the stability of the sample components or the nature of the final analysis. Use in cryogenic conditions, with liquid nitrogen, preserves the integrity of heat-sensitive or volatile substances, such as certain biomolecules.
The 10 mm diameter generates high impact energy while ensuring good stress distribution in the grinding bowl. This allows fine final particle sizes to be obtained, often in the order of a few microns, promoting efficient extraction or optimal homogenisation. To guarantee reliable results, it is essential to combine this bead with a stainless steel grinding bowl of suitable capacity, generally between 25 and 50 ml depending on the sample load and the configuration chosen.
Its stainless steel construction ensures excellent resistance to abrasion, corrosion and cross-contamination, which is essential in medical and pharmaceutical environments. The stability of the material also allows for safe reuse in standardised processes. It is frequently used in pre-analytical preparations, such as cell fractionation or DNA/RNA release, where grinding conditions are precisely controlled.
Reliable, robust and compliant with laboratory standards, this bead is an essential component for laboratories requiring rigorous and reproducible sample preparation.
