Abstract

Mixing without excessive heating is sometimes needed for temperature‐sensitive fluids. We modified an inexpensive low‐frequency electronic filter based on a mechanical resonator to produce a compact (16 mm) and low‐power (1–3 mW) mixer for low viscosity fluids. Tests made in air and methanol at room temperature and in fluoroform near its critical point are compared against the predictions of an electromechanical model.
