Centrifuges
A very broad spectrum of methods and scientific instruments are used in the life sciences, which encompass the disciplines of biology, medicine, biomedicine, biochemistry, molecular biology, biophysics and bio-informatics. Sigma laboratory centrifuges have an outstanding reputation in this area for their combination of performance, reliability in routine use and versatility in research. In clinical laboratory diagnostics, analyses of blood, urine and tissue, cell diagnostics and cytology are carried out under time pressure with stringent requirements for due care. Sigma laboratory centrifuges are designed for high throughput in laboratory diagnostics applications.
