ABSTRACT:
The specification discloses a method and apparatus for determining the gel time of thermoset resins by using a disposable vial, a disposable spindle for insertion into the vial, a locking collar releasably secured to the disposable vial for mounting the vial in a permanent sample cup and holding it against rotation with respect thereto, and a spindle adaptor releasably receiving the disposable spindle for mounting same to the spindle mount of a conventional viscometer. The thermoset resin is located in the disposable vial along with the disposable spindle. The permanent sample cup including the disposable vial and its contents is located in a heater and the spindle adaptor is secured to the spindle mount of the viscometer. The viscometer is operated and the gel time is determined as the length of time it takes until the viscosity of the heated resin sample begins to increase sharply.
