Evidently, development of lab-on-a-chip platform to monitor various physical parameters, such as density, pressure, diffusivity, viscosity etc., has enormous potential and wide-ranging applications in the diagnostics and medical fields. Although, various microviscometers have been developed in the past, they still possess limited applications due to their lack of reproducibility in measurements and limit-of-detection. In the present work, we describe the experimental validation of a 3D printed microviscometer for measuring adulteration of gasoline (petrol) with diesel and kerosene. The device analyzes the change in dynamic viscosity based on width occupancy of the fluids inside a microchannel. This microviscometer has been designed and fabricated using the Stereolithography (SLA) based Digital Light Processing (DLP) 3D printer. The tests were conducted on samples of several blending ratios of petrol, diesel and kerosene, and the results were found within an accuracy of 0.95. This device possesses several advantages like ease of operation, simple design and automation capabilities. Further, the device is amenable to be implemented in various applications where viscosity is the monitoring parameter. Copyright © 2017 American Scientific Publishers All rights reserved.
