<p><P>PROBLEM TO BE SOLVED: To enable measurement with a very small quantity of samples and with higher precision in a condition independently of surrounding influence. <P>SOLUTION: A viscosity measuring device includes a channel substrate having a flow channel 31 to flow a sample S of an object to be measured containing a micrometal sphere K, an air supplying channel 4 to separate the sample S flowing through the flow channel 31 as a micro-droplet S' containing one micrometal sphere K by supplying air E to the channel 31, electromagnets 5A, 5B to rotate a micrometal sphere K in the micro-droplet S', provided at predetermined locations on a side of lower than the air supplying section on the channel 31, an observing means 6 for observing the micrometal sphere K excited by the electromagnets 5A, 5B to obtain behavior data, and a viscosity calculation means for calculating the viscosity of the sample S from the behavior data obtained by the observing means 6. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
