Test Price:
$310 per analysis
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.
Detection Limit:
The limit of detection is matrix dependent.
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.
Equipment:
Brookfield Viscometers
Reportable Units:
Viscosity in centipoise
Turnaround Time:
7-9 business days
Is rush testing available?
Yes
Method Reference:
Internally-developed method
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.
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.
- Solution concentration (for samples submitted as powders)
- Temperature(s) at which to measure viscosity
- Spindle size
- Speed
- Timepoint(s) at which to measure viscosity
- Liquid type (Newtonian or non-newtonian, if known)
- Estimate of viscosity
- Units needed (if not centipoise)
- 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.
