Abstract
The invention provides a viscometer and an operation method thereof. The viscometer comprises a disk and at least one microfluidic structure. The microfluidic structure is embedded in the disk and has a first chamber which is connected to a second chamber. The second chamber is provided with an annular chamber along the circumferential direction of the disk and comprises at least one indicator. Overall, the present viscometer and its operation method do utilize the oscillation amplitude of pendulum motion of the indicator to calculate a viscosity value (cP) of a sample which has already existed in the second chamber.
Claims10
A viscometer comprising at least one microfluidic structure which is embedded in a disk, wherein the at least one microfluidic structure includes:
- a first chamber, having an injection hole, a sample injected into the first chamber via the injection hole to temporarily store in the first chamber;
- and
- a second chamber, connecting to the first chamber via a first microchannel, and the second chamber having at least one indicator;
- wherein at least one part of the second chamber is curved;
- wherein the viscometer further comprises a monitoring device that is configured to receive and calculate a viscosity value of the sample according to an oscillation amplitude of pendulum motion of the at least one indicator.
