Benchtop Vibration Viscometer
VM-10A
● The Viscomate series are vibrational viscometers that allow the quick and easy measurement of viscosity on a tabletop in a laboratory or control room.
● Only a very small volume of a sample is required (a minimum of about 1 ml depending on conditions), and measurement can be done by simply immersing the plunger in the liquid in any container.
● Cleaning is as easy as wiping off the plunger.
● Based on piezoelectric ceramics technology, actuation and detection of angular acceleration are performed by ceramic devices.
● These compact and easy-to-use viscometers are based on the phenomenon of resonance.
● The wetted part, i.e., the plunger, is extremely small, so these viscometers can even measure samples in very small volumes.
● These viscometers are based on the phenomenon of resonance, enabling highly accurate measurement with good resolution.
● Measurement takes very little time.
● Good reproducibility.
Uses
● Research and development of various liquids
● Receiving, sampling, and shipping inspections in the manufacturing process
● Research in medicine and pathology
Principle
● When the plunger, which is actuated by a piezoelectric ceramic, is immersed in a liquid, the vibrations are attenuated in proportion to the viscosity.
● This change in vibrations is detected by an acceleration sensor and displayed as the viscosity.
● The plunger has a piezoelectric ceramic actuator and is rotationally vibrated to resonate at a certain frequency.
When the tip (plunger) is immersed in a liquid, the amplitude of the vibrations changes depending on the viscosity of the liquid. A piezoelectric acceleration sensor measures those changes in amplitude as changes in angular acceleration and converts those changes in acceleration into an electrical signal to measure viscosity.
● These viscometers have a piezoelectric ceramic as an actuator and are based on the phenomenon of resonance of rotational vibrations (torsional vibrations). This method of measuring viscosity is an approach unique to our company (patented) and cannot be found anywhere else.
These viscometers are for universal use. Viscosity can be measured by simply immersing the plunger in a liquid. These viscometers can measure liquids in volumes as small as about 3-5 ml in any container. Cleaning is very easy: simply wipe off the plunger. The viscometer also comes with software to import data, so data can be recorded and saved by connecting to a PC.
