ST204A Fully Automatic Ubbelohde Viscometer
The ST204A fully automatic Ubbelohde kinematic viscometer is
suitable for the second method of Ubbelohde capillary viscometer
determination in General Rule 0633 of the Chinese Pharmacopoeia in
2025, as well as the USP<911>viscosity Ubbelohde capillary
method design and manufacturing. This method uses the relative
method to measure the time required for a certain volume of liquid
to flow through a capillary under the action of gravity, in order
to obtain the kinematic viscosity of the fluid.
The ST204 fully automatic Ubbelohde viscosity analyzer has a series
of fully automatic functions such as automatic temperature control,
automatic extraction, automatic timing, automatic calculation,
automatic printing, automatic cleaning, and automatic drying in
automatic mode. When in use, only one injection click is needed to
start the experiment.
