The difficulty with viscosity measurements of hot melts and liquids at elevated temperatures has been in maintaining accurate temperature control that is consistent from sample to sample so that meaningful data could be obtained. The Brookfield Thermosel solves this problem by providing a stable, precisely controlled sample environment. This, together with the inherent accuracy of the Brookfield Viscometers, is fundamental to the Thermosel System, which produces viscosity measurements that are not only accurate but entirely reproducible.
Several factors contribute to the stable environment:
Non-fluctuating temperature control Small sample volume and insulated sample chamber which reduces temperature gradients within the sample The rotating spindle, which acts as a built-in stirring device The test procedure is quite straightforward. Once familiar with the system, unskilled operators can easily produce accurate, reproducible data.
