Title:
VISCOMETER AND METHOD FOR MEASURING VISCOSITY
Document Type and Number:
WIPO Patent Application WO/2021/124713
Kind Code:
A1
Abstract:
Provided are a viscometer and a method for measuring viscosity that make it possible to accurately measure the bulk viscosity of a liquid sample in a tiny quantity such as 100 μL or less. A viscometer (1) comprising a securing member (31), an upper unit (10), a lower unit (11), and an information processing unit (50). Additionally, a method for measuring viscosity, the method involving: applying an AC voltage to a piezoelectric element (15) while varying a frequency; thereby measuring, through use of the information processing unit (50), a resonance response voltage from a means (19) that detects displacement of a leaf spring (17) in one direction, the displacement being associated with vibration of the upper unit (10); and measuring the viscosity of a sample.
