Method description

Viscosity is the resistance to the flow of liquid materials. Viscosity is measured by rotating a spindle attached to the viscometer in the liquid sample. The torque against the rotating spindle is converted to viscosity units.

Acceptable matrices

This method applies to liquid samples only. Powdered flours, hydrocolloids, proteins, etc. can be tested, if the directions on the procedure to disperse the sample into a liquid are provided with the submission.

Unacceptable matrices

Solids and extremely high viscosity liquids cannot be tested by this method.

Equipment

Brookfield Viscometers

Method reference

Internally-developed method

Reportable unit

Viscosity in centipoise

Sample size requirements

If requesting liquid as viscosity or a liquid for a viscosity/temperature profile, please provide a sample of at least 1 cup/200cc. If submitting a powder that will be reconstituted, please provide a sample of at least 25g.

Information required by submitter

The following information helps our team to provide an accurate price as well as design an appropriate test protocol if there is no specific method.

  1. Solution concentration (for samples submitted as powders)
  2. Temperature(s) at which to measure viscosity
  3. Spindle size
  4. Speed
  5. Timepoint(s) at which to measure viscosity
  6. Liquid type (Newtonian or non-newtonian, if known)
  7. Estimate of viscosity
  8. Units needed (if not centipoise)
  9. Brief description of how results would be used (to aid in determining the best viscosity method for your needs)

If known, please include a copy of the test method to be used.

Common Viscosity by Brookfield Viscometer Test Testing Questions

While our sales and customer service team are happy to answer general testing questions, consultations typically start at a rate of $250 per 30 minutes regarding the interpretation of reported test results or questions about our test methods. We cannot consult on regulations, tolerance limits, or claims.

We make every effort to keep our methods and detection limits up to date according to the latest standards and qualifications. If you have any questions regarding the limit of detection/quantification or method references, please contact our Customer Service team at 1-800-245-5615.

Our standard turnaround time is 10 business days for most assays. There are some assays that require a longer turnaround time. We also offer a RUSH service that is half the time of the standard turnaround time of the assay at double the cost of the assay. A few assays that we provide cannot be rushed due to the nature of the test. Please check the specific assay you are interested in regarding the ability to RUSH the turnaround time.
