ubbelohde viscometer

A practical method for the determination of intrinsic viscosity is with a Ubbelohde viscometer.

The Ubbelohde viscometer is closely related to the Ostwald viscometer.

Another version is the Ubbelohde viscometer, which consists of a U-shaped glass tube held vertically in a controlled temperature bath.

He was the inventor of a suspended-level viscometer used for determining kinetic viscosity, known today as a "Ubbelohde viscometer".
