A Couette viscosimeter.
Ogston & Stanier (1950, 1951, 1952) have referred to measurements made with a Couette viscosimeter. Since this viscosimeter can be constructed almost wholly in an ordinary laboratory workshop, and since it has proved to be convenient and accurate in CONSTRUCTION Drive. A type RQ synchronous motor, 73 rev./ min. (Drayton Regulator and IIistrument Co. Ltd.) is coupled by a stirrup coupling to the...
متن کاملHigh-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 ...
متن کاملTaylor instabilities in colloidal crystals
2014 Recently we have developed a Couette viscosimeter for studying the shearing of colloidal crystals. We report here that with increasing shear rate the colloidal crystal melts (for 03C9crit) and above a critical shear rate, 03C9T0, Taylor instabilities develop. After stopping the shearing flow the suspension recrystallizes in a special texture which preserves the pattern of the Taylor rolls....
متن کاملA Routine Method for Measuring Molasses Viscosity
Viscosity of molasses is determined under standard conditions (50°C, 80% Karl Fischer solids) using a Hoeppler viscosimeter. Samples are pretreated by dilution and concentration under vacuum to dissolve crystal and remove air. Measurements are made at two different concentrations, preferably slightly below and slightly above 80% solids and the required value obtained by extrapolation using the ...
متن کاملThe Significance of Changes of Viscosity in Pathological Sera
Measurements of the viscosity of blood serum reported by clinical observers have in many cases shown results that are seemingly paradoxical, as for example a small effect of high dilution on serum viscosity in nephrosis; a low serum viscosity in pernicious anemia, and a high one in icterus, though they are both characterized by a high bilirubin content of the blood; a low serum viscosity in man...
