Viscosity Standard Fluids
Brookfield Viscosity Standard Fluids provide a convenient, reliable way to verify the calibration of your Brookfield Laboratory Viscometers/Rheometers. Brookfield Viscosity Standards are Newtonian, and they are available as either silicone or oil.
Silicone Viscosity Standards
- Accuracy ±1%
- Excellent temperature stability
- Special viscosity values and temperatures available upon request
- Recommended for use with Brookfield and most other rotational viscometers
- Most economical
Oil Viscosity Standards
- Accuracy ±1%
- Appropriate for use at shear rates greater than 500 sec-1
- Recommended for use with Cone/Plate viscometers at viscosities above 5000 cP
- Recommended for Brookfield CAP series and KU-1+ viscometers
Brookfield Viscosity Standard Fluids are accurate to ±1% of the stated viscosity and are certified by methods traceable to the United States National Institute of Standards and Technology (NIST). The selection of one or two fluids will normally provide sufficient measurement points to verify calibration of your instrument. All fluids are supplied in ½ liter (1 pint) containers and with a certificate of calibration.
Special Order Silicone Fluids
- Viscosity Blends at 25oC (77oF)
Fluids may be ordered with viscosities other than those listed for general purpose silicone fluids.
- Minimum: 5 cP (mPaos)
- Maximum: 60,000 cP (mPa·s)
- Blends will be within ±2% of requested value
- Temperature Calibrations
General purpose or blended fluids may be calibrated at temperatures other than 25oC (77oF).
- Minimum: 20oC (68oF)
- Maximum: 80oC (176oF)
- Minimum temperature increment: 2oC
GENERAL PURPOSE SILICONE FLUIDS
Brookfield Silicone Viscosity Standards provide a convenient, reliable means of checking the calibration of most Brookfield Viscometers/Rheometers. These fluids, calibrated at 25oC (77oF), are available in 11 different viscosity ranges.
