Cannon-Ubbelohde Viscometer, Calibrated - Laboratory Glassware For Viscosity Measurement (Part #9721-K71)

About This Product

For the scientists and lab techs out there: this is a calibrated Cannon-Ubbelohde viscometer, a precise piece of glassware used to measure the viscosity (thickness/flow resistance) of liquids. It works on the capillary tube principle—you time how long it takes for a liquid to flow between two marked points under gravity. The specific model number is 9721-K71, and it comes calibrated for accurate results.\n\nThese are essential in quality control, research, and development for industries like petroleum, chemicals, paints, cosmetics, and food. The design minimizes errors from surface tension and is known for its reliability. Made from borosilicate glass, it can handle many lab chemicals. Just note: this listing appears to be for the viscometer itself, though the description mentions stoppers (maybe a mix-up). Always verify the exact product details and calibration certificates for your application. A professional tool for precise fluid analysis.
