Compliance Standard: ASTM D446 – Standard Specifications and Operating Instructions for Glass Capillary Kinematic Viscometers, ASTM D445 – Kinematic Viscosity of Transparent and Opaque Liquids, IP 71 / ISO 3104 (depending on model type)
Application : Capillary Glass Viscometers are used for the determination of kinematic viscosity of transparent and opaque Newtonian liquids by measuring the time required for a fixed volume of liquid to flow under gravity through a calibrated glass capillary.
Widely used in petroleum refineries, lubricant testing laboratories, chemical industries, research institutions, and quality control laboratories.
Typical applications include: Petroleum products and lubricating oils, Fuels and fuel oils, Polymers and resins (low viscosity), Chemicals and solvents
Product Description : The Capillary Glass Viscometer is a precision-manufactured borosilicate glass instrument designed for highly accurate viscosity measurement. Each viscometer is individually calibrated and supplied with a unique calibration constant. The viscometer ensures excellent thermal stability, chemical resistance, and repeatability, making it suitable for routine as well as reference laboratory measurements.
Available in various internationally accepted designs such as:
- Ubbelohde Viscometer
- Cannon–Fenske Routine Viscometer
- Reverse Flow Viscometer
- Suspended Level Viscometer
