More About this Item

Determine the gel time of thermosetting compounds such as resins, styrenes, monomers, formaldehydes, thermosetting foodstuffs, and other polymerizable materials. The gelation point is characterized by a sudden increase in material viscosity and the meter senses the increased torsion on a slowly rotating glass spindle in the sample. At the gel point, the timer automatically stops and an audible buzzer signals the user that the gel point has been reached.

Achieve reproducible results by controlling the temperature of your sample. An immersion heater is included — plug the heater directly into a power source, or use a temperature controller for more precise control (not included, order separately below). A cooling coil at the top of the assembly helps prevent evaporation which could alter the level of liquid in the bath jar.

Optional starter kit (sold separately) includes twelve test tubes, twelve stiring rods, twelve Allen screws, and one Allen wrench — ideal when running multiple tests.
