Technical data sheet

Method description

A slurried sample is taken through a programmed heat-hold-cool cycle while the viscosity is continuously measured. Differences from the Visco-Amylograph include much smaller sample sizes and the ability to program heating and cooling rates that can change much more quickly than the Amylograph.

Unacceptable matrices

Low-viscosity liquids (i.e. vegetable oil)

Equipment

Rapid Visco Analyzer (RVA)

Method reference

Internally-developed methods and AACC methods for grains and grain milling products:

  • AACC 22-08
  • AACC 61-02
  • AACC 76-21

Reportable unit

N/A RVU (Rapid Visco Units)

Sample size requirements

100 grams

Information required by submitter

Because each segment of the grain industry uses different sample sizes and temperature profiles, the customer must supply a method reference with the samples. Medallion Labs prefers AACC methods.

Additional information

The RVA is an empirical viscometer used to measure the pasting properties of grains, starches, and flours. Because each segment of the grain industry uses different sample sizes and temperature profiles, customers must supply a method reference with the samples. The submitter is encouraged to speak to our test specialist to design an appropriate test protocol if there is no specified method.

Common Viscosity by Rapid Visco Analyzer 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.
