A heater/mixer device is disclosed for use with laboratory vials, test tubes, or similar containers containing liquids. The heater/mixer includes a chamber formed in a block of material such as aluminum, with an electric heating element in contact with the block. The vial fits loosely in the chamber. Compressed air passes into the chamber through an inlet in the block, so that the vial is revolved by a circular air flow in a vortex fashion. This revolving motion creates a vortex in the liquid inside the vial, and so mixes the liquid. The air circulation also improves heat transfer from the block to the vial.
