This geometry gives researchers a sophisticated instrument for routinely determining absolute viscosity of fluids in small sample volumes.

The Wells-Brookfield Cone/Plate Viscometer/Rheometer provides a wide variety of shear rates and viscosity ranges, which can be further extended by the use of interchangeable cone spindles. Different models can be selected to meet the specific range of viscosities and shear rates required.

Shear rates as high as 1,875 sec^-1 (DV-III Ultra Rheometer) can be achieved. The small sample volume required permits rheological evaluations to be made on materials where sample availability is limited, such as biological fluids and thick film coatings that contain precious metals. All wetted parts are stainless steel for corrosion resistance and ease of cleaning.

Optional purge fitting, luer fitting, and embedded temperature probe available.

Wells-Brookfield Cone/Plate Digital Viscometers/Rheometers are now supplied with an advanced Electronic Gap Setting feature. This technology allows faster set-up time and minimizes the possibility of gap adjustment errors.

• Determine absolute viscosity of small samples (0.5 - 2.0 mL)
• Precise shear rates for determining a material's flow curve behavior
• Rapid temperature control due to small sample size
• Electronic gap adjustment for simplified setup and increased throughput
• Available on DV-III Ultra Rheometer and DV-II+Pro and DV-I Prime Viscometers
• Automatic data collection and historical comparison with optional Wingather software (for DV-I Prime and DV-II+PRO models) and Rheocalc software (for DV-II+PRO and DV-III Ultra models)
• Torque measurement accuracy: 1% of full scale range; Repeatability: 0.2% of full scale range
• NIST traceable viscosity standards available
