High-throughput viscosity determinations

A new high-throughput viscosimeter device was designed, built, and tested allowing measurement of the viscosity of 100 different solutions in a single experiment using the falling sphere approach. Using the corrected Stokes' law, viscosities obtained by the HT device were compared to viscosities of the same solutions obtained on a conventional viscosimeter and showed excellent correlation. The theoretical set of data, correlated with Reynolds numbers, and the viscosities obtained for each sample showed very good correlation with the experimental data, demonstrating the robustness of the device.
