Disposable chambers for use with accessories like Small Sample Adapter (see Figure 1) require 16mL or less, depending on spindle used, and can be discarded after the test is run. The test apparatus used to make the viscosity measurement can be selected to work specifically with small sample sizes.

Grab samples from the production floor may be up to a half-liter or more in size, when perhaps much less will do.

Many do not get reviewed to see if they still make sense or are being done in the most practical way. SAMPLE SIZE: QC viscosity test methods have been in existence for ages. Reduce the time required to run the viscosity test procedure Control sample temperature as quickly as possibleģ. Reduce sample size to the minimum necessaryĢ. There are four factors to consider as lab manager that can reduce test time and/or improve the usefulness of test results:ġ. Rapid turnaround time in viscosity testing is fundamental to Quality Control’s role in improving product consistency and minimizing batch rework or outright rejection. Many small changes, like reduction in sample size and shortening the viscosity test time, can lead to significant increase in QC lab productivity. This knowledge will allow you to have assurance that your product is consistent from lot to lot and conforms to customers expectations.įor complex engineering systems, understanding the viscosity of a product is vital for much more involved reasons, as in determining what type of pumps are needed, the piping system required and how the material may change at different temperatures and shear rates.Ĭontact Dynalene Laboratory Services at viscometers are the most widely used tool in today's QC labs for making viscosity measurements. Determining the viscosity of your material can be important for something as simple as the thickness of your shampoo. Multiple Techniques Quick Turnaround Flexible Services Reasonable Rates. We also have the classic Brookfield Viscometer and Cannon-Fenske Viscometers for kinematic viscosity. Quality Control Design Engineering Material Characterizationĭynalene has 3 techniques to determine the viscosity of your products! We can obtain more complex information with our TA Instruments AR-G2 Rheometer, including Yield Stress, Shear Thinning/Thickening, Thixotropy, etc.
