Abstract
The gelation time of a gelling solution can be determined using viscosity-time data obtained at constant temperature. An instrument has been developed which enables the gelation time of a solution gelling to be measured at constant temperature. The viscosity is measured in terms of the free fall velocity of spherical drops of carbon tetrachloride through the gelling solution which is measured electronically using a fibre optics detector system. The quantity recorded and displayed digitally by the instrument is the fall time, or the time taken for a drop to fall between two fixed points. The gelation time, tg, can be calculated using an empirical relation which accurately describes the solution viscosity as a function of time up to the point of gelation.
