Mills and grinders are used for to break dry or wet samples into smaller particles by grinding, crushing, or cutting. Blades are used in mills to cut up samples into finer particles. Hand-held and bench top homogenizers blend chemical or biological samples thoroughly using various methods. Sonicators are homogenizers that use sound energy …

Resistive pulse sensing (RPS) is an analytical method that can be used to individually count particles from a small sample. RPS simply monitors the physical characteristics of particles, such as size, shape, and charge density, and the integration of RPS with biosensing is an attractive theme to detect biological particles such as virus and …

30.4.2 Grinders . The term grinder describes a variety of size-reduction machines for intermediate duty. The product obtained from a crusher is often fed to a grinder to reduced the particle to powder. The common types of grinders are hammer mills and impactors, rolling-compression machines, attrition mills, and tumbling mills.

Abstract. Light scattering techniques used in biology provide a fast, non-destructive probe that is very sensitive to small but significant biological changes that are not seen by any other optical technique. The S 34 component of the scattering matrix is particularly sensitive to temporal changes in the biosystem as depicted in several examples.

From biological standpoint, coarse particles are more recalcitrant to enzymatic digestion than fine ones. It was confirmed by LLD analysis of pSCB when only a decrease of fine population was observed during the first moment of enzymatic hydrolysis (15.3% hydrolysis rate). However, FBRM was not able to characterize this change in PSD.

Crack-U-Lators produce narrow particle distributions with a controlled cracking process between longitudinal and/or circumferential cuts on mating rolls. Reduce size to anywhere between 4 to 325 mesh or 4,760 to 50 microns. Less fines produced, meaning better yields and more profit. Complete CIP designs available.

In its various forms grinding can be used on wet, dry, and frozen samples. A relatively soft sample placed between two hard, scraping surfaces will wear down. With adequate patience, solids can be reduced to very fine particles by grinding, part of which is dependent upon the topology of the grinding surfaces.
