With their high shear processing, high shear homogenizers are essential for homogenization in many industries.

A dry biochemistry analyzer is a clinical laboratory instrument used to measure the concentrations of biochemical analytes in biological samples, such as serum, plasma, and whole blood, using dry reagent technology, and it is used in clinical laboratories, point-of-care settings, and diagnostics for the rapid assessment of biochemical parameters. The dry biochemistry analyzer uses dry reagent slides or discs, which contain the reagents in a dry form, and the sample is applied to the slide, and the reaction takes place, and the color change or other signal is measured by the analyzer, and the concentration of the analyte is calculated; the dry reagent technology eliminates the need for liquid reagents and the associated preparation, and it provides a rapid and convenient analysis, with features such as a small sample volume, and it is suitable for point-of-care testing and for small laboratories; the dry biochemistry analyzer measures the common biochemical analytes, such as glucose, urea, creatinine, total protein, albumin, bilirubin, and the enzymes, and it provides the results rapidly, with features such as automated operation and data management; the analyzer is available as benchtop and portable instruments, and it is used for the analysis of blood samples, and it is suitable for the emergency and critical care settings. Dry biochemistry analyzers are used in hospital laboratories, in emergency departments, in clinics, in veterinary practice, in small laboratories, and for many other applications, and they provide a rapid biochemical analysis. With their dry reagent technology, dry biochemistry analyzers are essential for rapid biochemical testing.
