We describe a microfluidic trap, for analysis of fluids and suspensions, that simulates the function of a four-roll mill, a rheological tool with adjustable flow type and rate. These flow characteristics were designed with the assistance of flow simulations and are measured here by micro-particle-image-velocimetry.
