Brookfield viscometer

DVNext Cone / Plate Rheometer ​

The DVNext Wells-Brookfield Cone/Plate Rheometer, now with an easy to change magnetic cone/plate, gives researchers a sophisticated instrument for routinely determining absolute viscosity of fluids in small sample volumes. Its cone and plate geometry provides the precision necessary for development of complete rheological data.
