Ostwald viscometer

[′ȯst‚vält vi′skäm·əd·ər]
(engineering)
A viscometer in which liquid is drawn into the higher of two glass bulbs joined by a length of capillary tubing, and the time for its meniscus to fall between calibration marks above and below the upper bulb is compared with that for a liquid of known viscosity.

The viscosity of the resin calculated by Ostwald viscometer (calibrated) using Gallenkamp water bath (thermostatic).
Viscosity of Schiff base prepared as well as of resin was assessed by standardized Ostwald Viscometer. The synthetic resin and the Schiff base having a concentration ranging from 0.024 to 0.064 g/dL were provided by DMF accumulation in samples reweighted in a volumetric flask.
Solution viscosity was obtained from a one-point method (22) using an Ostwald viscometer at 25 [degrees] C with the concentration of polycarbonate solution of 0.005 g/ml.
