Full Detailed Description

SI Analytics Ubbelohde Viscometer Item No.285400501, Type 50100, premium German manufactured suspended-level capillary glass viscometer (formerly SCHOTT lab instrument). Classic Ubbelohde suspended-level design ensures measurement results independent of sample filling volume, which is ideal for serial dilution experiments of highly dilute polymer solutions. Capillary 0 with inner diameter of 0.36 mm, covering low kinematic viscosity range from 0.2 to 1 mm²/s.Fabricated from chemically stable DURAN borosilicate glass, fully compliant with international standards DIN 51562-1 and ISO 3105. Each viscometer undergoes strict factory calibration and is equipped with traceable calibration certificate, meeting laboratory audit and standardized testing requirements. Specially optimized for low-viscosity transparent Newtonian fluids. Users can conduct manual timing measurement, or match with SI Analytics AVS series automatic viscosity measuring systems to realize high-throughput automatic detection. Widely adopted in polymer science, fine chemical industry, new material research and analytical chemistry laboratories.

During the measurement process, you can measure the time it takes for a quantified fluid to flow through a capillary of known diameter and length. With the industrialized production of precisely calibrated glass capillary viscometers, SI Analytics has paved the way for the capillary viscometer method to become a globally reliable standard for viscosity measurement. To install these viscometers in measurement systems, a variety of accessories are available, such as AVS measuring stands or holders. Among them, the measuring stand can be used to automatically record the time it takes for the fluid to flow through the capillary. All accessories can be used with standard viscometers for repeated measurements and can be connected to all measurement systems.

SI Analytics GmbH (SIA) was formerly known as SCHOTT Instruments GmbH (a subsidiary of the US-based Nova Analytics Group). Starting with the successful launch of the first glass electrode 65 years ago, SI Analytics established its success in the field of electrochemical detection. With the release of high-performance pH glass, innovative electrodes, and electrochemical measuring instruments like pH meters, conductivity meters, dissolved oxygen meters, piston burettes, and automatic titrators, SI Analytics has always believed that electrochemical detection is an essential, easy, and reliable method worldwide today. The company's core products are sensors and instruments.

Product Feature

Viscometers suitable for the dilution viscosity method

Viscometers with suspended liquid levels for determining the absolute and relative kinematic viscosity of liquids with Newtonian flow characteristics. Thanks to their unique design, these viscometers are especially suitable for measuring small volumes of liquids and liquids with extremely short flow times. All viscometers are equipped with ring marks, which ensure that measurement values obtained via automatic measurement with the viscometer can also be acquired manually.

The calibrated viscometer is supplied with a manufacturer’s certificate complying with DIN 55 350 Part 18. For measurements using an automatic viscosity measuring instrument, there is an additional effective constant, which is obtained by multiplying the constant K by the correction factor F.
