Partec reagents for industrial applications are widely used for analysis of physiological parameters for cells of various microorganisms, e.g. employed in fermentation processes. Detection of sub-optimal growth conditions at an early stage is a necessary requirement for efficient fermentation control and can best be done by monitoring the growing cells.
 
Beads of various diameters to be used as calibration standards for particle size are available for Partec flow cytometers. Particle counting and size distribution measurements for all types of samples are now easy to standardize.
