Abstract
The capillary viscosimeter (Viscotimer) tested with different Ubbelohde-viscosimeters is suitable for measurements of plasmaviscosity; the limitting factor of the measuring method is the exact adjustment of the temperature. When testing the plate-cone-viscosimeter (Wells-Brookfield Microviscosimeter), we achieved scientifically adequate results only when using shear rates 230, 115 and 46 sec−1. An influence of different thrombocyte-concentrations on the viscosity of whole blood and plasma could not be detected. The flow capacity of whole blood and plasma is distinctly dependent on the temperature.
