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

Newtonian measurements made simply and easy!

The Höppler principle is used to measure the viscosity of Newtonian liquid by measuring the time required for a ball to fall under gravity through a sample-filled tube that is inclined at an angle. The average time of three tests is taken; the result is converted into a viscosity value using a simple formula.

Two models are available:
KF10 has a fixed angle of 80° and complies with DIN 53015
KF20 can be angled at 50°, 60°, 70° and 80°.

• Pivot bearing allows for quick and easy tube rotation - ideal for repeat tests
• Connection to circulating bath for temperature control of sample
• Set of six balls to test a wide variety of samples
• Complete with temperature probe
• Accuracy 0.5% to 2.0% depending on ball being used

Designed to meet the parameters of ASTM D4212. It is constructed of a solvent and corrosion resistant stainless steel and consists of a bullet-shaped cup which can hold up to about 48 ml.

The viscosity range of the cup is determined by a precision-drilled orifice in the bottom of the cup. A 12-inch loop handle allows the cup to be dipped into a liquid container.

Dip Viscosity Cups (Zahn Type) are robust instruments which are inexpensive and easy to operate. They may be used anywhere to test the viscosity of a wide variety of fluids in accordance with ASTM Standard Test Methods D816, D1084, or D4212. Ranges of viscosity from about 20 to 1800 centistokes (cSt) for different materials can be evaluated with a set of five different cups.
