53211 SI Analytics (Xylem Analytics) DIN Ubbelohde Capillary Viscometer-Labcan Scientific

Product Description

SI Analytics 53211 Ubbelohde Viscometer, normal form DIN (Part No.285400172) is a German-manufactured suspended-level glass capillary viscometer, designed for precise determination of kinematic viscosity and intrinsic viscosity of transparent Newtonian fluids.

Fabricated from premium DURAN borosilicate glass, this DIN standard Ubbelohde viscometer strictly follows DIN 51562 and ISO 3105 specifications. The Capillary Ia offers a measuring range of 10–50 cSt, widely suitable for medium-viscosity solvents, base oils, biodiesel and dilute polymer solutions.

The suspended-level structural feature enables measurement independent of filling volume, delivering excellent repeatability, especially ideal for serial dilution tests of polymer solutions according to ISO 1628. Permanently etched timing ring marks support reliable manual timing measurement. It can be matched with thermostatic baths and SI Analytics automatic viscosity measuring instruments to satisfy routine laboratory quality control and academic research measurement requirements. Every viscometer is individually calibrated in Germany and supplied with official calibration constant and certificate.

Long Paragraph Version

Precision hand-blown DURAN borosilicate glass construction delivers strong resistance to thermal shock and most common laboratory solvents. Standard DIN normal-form configuration ensures consistent test results and complete data traceability to meet European international testing specification requirements. The unique suspended-level design eliminates measurement deviations caused by inconsistent filling volume, greatly simplifying repeated dilution analysis for polymer research. Each viscometer undergoes separate calibration in Germany, with documented viscosity constant K for direct viscosity calculation. Optimized Capillary Ia bore ensures stable laminar flow within viscosity interval of 10–50 cSt. Clear permanent etched timing rings avoid abrasion and guarantee accurate reading in long-term usage. It supports both manual stopwatch measurement and automated detection with SI Analytics viscosity instruments, widely adopted in industrial QC laboratories, third-party testing institutions and university material research labs.
