ST204A Fully Automatic Ubbelohde Viscometer

The ST204A fully automatic Ubbelohde kinematic viscometer is designed and manufactured for the determination method of Ubbelohde capillary viscometer in Method 2 of General Rule 0633 of the Chinese Pharmacopoeia (2025 edition) and the viscosity-Ubbelohde capillary method in USP <911>. This method employs a relative method to measure the time required for a certain volume of liquid to flow through a capillary under the influence of gravity, in order to determine the kinematic viscosity of the fluid.
The ST204A automatic Ubbelohde kinematic viscometer features a range of fully automated functions in automatic mode, including automatic temperature control, automatic extraction, automatic timing, automatic calculation, automatic printing, automatic cleaning, and automatic drying. When in use, simply inject the sample once and click start to complete the test.
