Abstract

We present a Multi-sample Micro-capillary Rheometer (MMR) which is capable of measurements over a broad range of temperatures, viscosities and shear rates. The instrument is simple as the flow is generated by external gas pressure and the shear rate is measured optically. We test the MMR against two National Institute of Standards and Technology (NIST) Standard Reference Materials (SRMs), three low viscosity standards and one commercial polymer (Polydimethlysiloxane, Polyisobutylene solution, Oils and Polystyrene) and report a high level of accuracy and precision. This instrument will be particularly useful as a combinatorial method and in cases of limited material quantity (typical sample size _ 20 μL). The dynamic range of the instrument is eight orders of magnitude in viscosity and four orders of magnitude in shear rate.
