See the full range of Viscosity Measurement products on our online store.

In addition to Instrument Sales we offer:


• Application Support
• On-site evaluation of customer samples
• User Training
• Maintenance, Repair and Service Contracts
• Instrument Spares
• Viscosity Standards
• Instrument Installation, Calibration and on site IQ/OQ

In recent years the ranges of Viscometers and Rheometers have been complimented with ranges of instrumentation for
Texture Analysis and Powder Flow Testers.

Now more structured samples such as set yoghurts whose properties can not easily be measured by Viscometers can be
characterised in terms of set strength, hardness, cohesiveness, mouth feel etc using a Texture Analyser.

Variations in the properties of Powder Raw Materials can be readily characterised by the Brookfi eld Powder Flow Tester (PFT).
Product consistency and formulation changes can be evaluated by quickly testing on a user friendly robust QC and Research
tool.

Viscosity Standards

Brookfield Viscosity Standards provide a convenient, reliable way to verify the calibration of your Brookfield Laboratory Viscometer/Rheometer. Brookfield Viscosity Standards are Newtonian, and they are available as either silicone or oil. Silicone fluids are less temperature sensitive than oil fluids.

Note: Brookfield recommends that all fluids be replaced annually.

Silicone Viscosity Standards

These fluids are most commonly used to verify calibration of Brookfield Viscometers/Rheometers.

Accuracy: ±1% of
viscosity value


Excellent temperature
stability


Recommended for use
with Brookfield and
most other rotational
viscometers


Most economical


Special viscosity values
and temperature
calibrations available
upon request

VisCal Kit

The Brookfield VisCal Kit provides all the necessary items to verify calibration of
your Viscometer/Rheometer.
Includes Brookfield
600mL Beaker, 1 pint of Silicone Viscosity Standard, Dispersing Bottle for cleanup
and Trapper Cleaning Agent.*


*Trapper Cleaning Agent available only in shipments within the USA

Plastic VisCal Kit

The Brookfield Plastic VisCal Kit provides all the necessary items to verify calibration of your Viscometer/
Rheometer in a glass-free environment.
Includes Brookfield 600mL Plastic Beaker, 1000ml of Silicone Viscosity Standard (5-12,500 cP) in a plastic
bottle and a Brookfield designed metal lid for anchoring beaker in the
temperature bath.

Special Order Silicone Fluids

For our customers needing a nonstandard viscosity or temperature range, our silicone fluids can be modified to meet most requirements.

VISCOSITY BLENDS CALIBRATED AT 25°C (77°F)
- Minimum: 5 cP (mPa•s)
- Maximum: 60,000 cP (mPa•s)
- Blends will be within ±2% of requested value

TEMPERATURE CALIBRATIONS
- Minimum: 10°C (50°F)
- Maximum: 80°C (176°F)
- Minimum temperature increment: 2°C

Please contact us at brookfield@labunlimited.com for more information.
Or view the Brookfield product range on the Lab Unlimited online store.

Oil Viscosity Standards

These fluids are used for specific instruments using cone/plate or Krebs spindle geometry. Also, certain industries may require use of oil standards.

Accuracy: ±1% of viscosity value
Appropriate for use at shear
rates greater than 500 sec-1

Recommended for use with
cone/plate Viscometers at
viscosities above
5,000 cP


Recommended for
Brookfield CAP series
and KU-2 Viscometers
and R/S Rheometers


Brookfield oil viscosity
standards are hydrocarbon
based, either mineral oil or polybutenes

Note: Other oil fluids are available – email brookfield@labunlimited.com for details.


Brookfield Viscosity Standards 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 1/2 liter (1 pint) containers complete with a certificate of calibration. CAP Oil Fluids are supplied in 150 mL (4 oz) containers.

HOW TO SELECT A CAP FLUID
- Determine which viscometer is being used: High Torque or Low Torque.
- Determine which temperature model is being used:
Low Temperature (5°C-75°C) or High Temperature (50°C-235°C)
- Determine which cone is being used.

Technical Support

We here at Lab Unlimited are the only company in Ireland who can calibrate your Brookfield viscometer to manufacturer specifications, providing the most accurate and fully traceable calibration.

Preventative Maintenance and Calibration is not simply cleaning down an instrument followed by a check with a Calibration Standard. We verify the instrument 'As found' and then routinely change instrument wearing parts in the course of the PM / repair. The uniqueness in our service is that the Instrument is adjusted into tolerance and 'Tuned' to a Brookfield Certified Master Viscometer.

A full complement of services are available

  • Application Support
  • On-site evaluation of customer samples
  • User Training
  • Maintenance, Repair and Service Contracts
  • Instrument Spares
  • Viscosity Standards
  • Instrument Installation, Calibration and on site IQ/OQ
