Viscometers are used to determine the viscosity of a fluid under specific flow and atmospheric conditions viscometers are used for a range of applications including product development, research and quality control there are several types of viscometers, including rotational, capillary, falling . Our test laboratory houses a myriad of rheometers, viscometers, spindles, plates and other accessories that can provide you with a viscosity analysis on most samples, including: suspensions emulsions. Rheometers & viscometers ‹ lab portable viscometers measure viscosity in the lab, in the field, or in a production environment video spotlight. Brookfield has a reputation of being the world leader in viscosity measurements for over 80 years providing a variety of laboratory viscometers to suit a wide variety of applications.

Glass capillary viscometers fisherbrand™ glass kinematic viscometer tubes cannon™-fenske type viscometer tubes for measuring kinematic viscosity of petroleum products by astm™ d 445. Professional rotational viscometer - precision viscosity measurement for laboratory & research - compliance with international testing standards. Chapter 2: liquid viscosity measurement such variation is beyond the scope of this laboratory however, changes in temperature are viscometer to normal .
Viscosity measuring equipment from cambridge viscosity, inc includes laboratory and process viscometers in a wide array of platforms cambridge viscosity's proprietary technology offers an elegant and simple solution to viscosity control. A viscometer, viscosity meter or rheometer is a measuring instrument used to determine a fluid's internal flow resistance or in the chemical laboratory, however . Viscosity is measured by rotating a spindle attached to a viscometer in the liquid sample the torque against the spindle is converted to viscosity units. There are several types of viscosity measurement devices viscometers measure viscosity of a fluid this article explains how to measure viscosity the different types of viscosity measurement devices are explained, such as portable viscosity testers, falling sphere viscometers, piston viscometers, and u tube viscometers. The most common method of determining kinematic viscosity in the lab utilizes the capillary tube viscometer (figure 1) in this method, the oil sample is placed into a glass capillary u-tube and the sample is drawn through the tube using suction until it reaches the start position indicated on the tube’s side.
Conversely, the viscosity of a non-newtonian fluid does depend on the shear rate “the customer would choose a viscometer for a newtonian fluid and a rheometer for a non-newtonian fluid,” kreiman says. The falling ball viscometer typically measures the viscosity of newtonian liquids and gases the method applies newton’s law of motion under force balance on a falling sphere ball when it reaches a terminal velocity. Gravimetric capillary is the most common technique used to measure kinematic viscosity it is temperature controlled, usually 40 ºc for single grade oils, and both 40 and 100 ºc for multi-grade oils the relation between viscosity and time determines the measurements using capillary viscometers . Professional ku-viscometer - precision krebs stormer viscometer for laboratory & research - compliance with international testing standards.
Experiment 1 viscosity measurement purpose the purpose of this experiment is to measure the viscosity of a glycerin-water mixture with a thomas-stormer viscometer. Automatic viscometers are specifically developed for industrial users in non-laboratory environments they can measure the kinematic viscosity of engine, gear, and industrial lubricants at either 40 or 100 degrees c digital paddle viscometers accurately measure the viscosity of emulsified asphalts, suspensions, marine fuels, residual oils . Instant high precision viscosity in the lab, on factory floor or on the move and remain completely inert to the reaction all portable viscometers are factory .
With this viscometer we can now get the data we need to tune our mathematical models and correlations and increase the accuracy of our viscosity predictions we question everything and copy nobody every product is unique. Use viscometer calibration standards from grainger to help reliably verify and calibrate laboratory viscometers find silicone and oil viscosity standards here. Cambridge viscosity’s viscolab line of viscometer instruments are accurate, reliable, and proven in laboratory settings worldwide.
