The Cannon-Ubbelohde CUU-300 uncalibrated viscometer has a 50 to 250 centistokes (cSt) viscosity measuring range and is suitable for the measurement of transparent Newtonian fluids such as fuels and lubricants. It uses a viscometer constant of 0.25 centistokes per second (cSt/s) for calculating kinematic viscosity. The CUU-series size 300 viscometer uses a 254mm depth water bath (not included) for temperature-control testing and a vacuum (not included) to draw a sample up for timed testing between two sets of printed marks. This uncalibrated viscometer is suited for use at temperatures above 93 degrees C (200 degrees F) or below -18 degrees C (0 degrees F) and meets the ASTM International D445 standard for testing viscosity. A viscometer, also called a viscosimeter, is an instrument used to measure the friction caused by the relative motion of a Newtonian fluid and a known surface, and is usually expressed in units of poise (P), centipoise (cP), pascal seconds (Pa s), and millipascal seconds (mPa s). Viscometers have several forms, including but not limited to falling ball, rotational, vibrating, capillary, funnel, and bubble. A falling ball viscometer measures the time it takes for a ball of known diameter and density to fall through fluid in a cylinder of known diameter. A rotational viscometer measures the force required to stir a fluid. A vibrating viscometer measures the power input necessary to keep the oscillator vibrating at constant amplitude while immersed in a fluid. A capillary viscometer has a narrow-bore vertical section with two printed marks that measure time required for a known volume of fluid to fall a known distance. A funnel viscometer, such as a Ford, Zahn, or Shell cup, measures the time it takes a known volume of fluid to flow from the base of a cone through a short tube. A bubble viscometer measures the time required for an air bubble to rise through a fluid. Viscosity measurements are used in laboratories, research and development, process control, and plant quality control applications...

Manufacturer: COLE-PARMER Brand: EZ

Easily measure viscosity using an EZ viscosity cup and a stopwatch. Simply fill the cup by immersing it in the test liquid. After withdrawing the cup, measure the time it takes until the first break in the liquid stream. Each cup is supplied with a conversion table to determine viscosity in centistokes (cSt) from the elapsed time. Each stainless steel cup meets dimensions as specified in ASTM D 4212 standards. An easy and economical way to measure viscosity ±3% production tolerance
