A laboratory evaluation of the HAAKE falling ball microviscometer

Abstract

The HAAKE falling ball microviscometer has been assessed during its routine use as a plasma viscometer in the laboratory over a two year period. The instrument generally performed well with acceptable precision ranges with normal and hyperviscous plasma. The small volume of sample required enhanced its potential as a suitable instrument for the discrete analysis or small batch analysis of Newtonian fluids particularly where the budget is limited.
