Cone Plate Wells Brookfield Viscometer

The Wells-Brookfield Cone/Plate Viscometer gives researchers a sophisticated instrument for routinely
determining absolute viscosity of fluids in small sample volumes. Its cone and plate geometry provides the
precision necessary for development of complete rheological data.

PRINCIPLE OF OPERATION
The Wells-Brookfield Cone/Plate Viscometer is a precise torque meter which is driven at discrete rotational
speeds. The torque measuring system, which consists of a calibrated beryllium-copper spring connecting the
drive mechanism to a rotating cone, senses the resistance to rotation caused by the presence of sample fluid
between the cone and a stationary flat plate.
The resistance to the rotation of the cone produces a torque that is proportional to the shear stress in the
fluid. This reading is easily converted to absolute centipoise units (mPa·s) from pre-calculated range charts.
Alternatively, viscosity can be calculated from the known geometric constants of the cone, the rate of rotation,
and the stress related torque.
The correct relative position of cone and plate is obtained by following a simple mechanical procedure without the
need for external gauges or supplementary instrumentation.
The stationary plate forms the bottom of a sample cup which can be removed, filled with .5 ml to 2.0 ml of sample
fluid (depending on cone in use), and remounted without disturbing the calibration. The sample cup is jacketed and
has tube fittings for connection to a constant temperature circulating bath.
The system is accurate to within ±1.0% of full scale range. Reproducibility is to within ±0.2%. Working temperature
range is from 0°C to 100°C.
Various cone spindles are available for use with the Wells-Brookfield Cone/Plate instruments. One cone spindle is
provided with the instrument and is calibrated for use with the sample cup. Additional cone spindles may be purchased
and will be calibrated for use with the same sample cup.

VERSATILITY OF APPLICATION
The Wells-Brookfield Cone/Plate Viscometer 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 1875 sec-1 (DV3TCP) 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.

ELECTRONIC GAP SETTING
Wells-Brookfield Cone/Plate Digital Viscometers 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. With the enhanced
system, a bright LED lights up when a hit point is achieved. A simple turn of the micrometer adjustment ring and the
gap is set, reducing the time required associated with manual detection methods.
The new electronic gap setting system is now a standard feature on our complete line of Wells-Brookfield Cone/Plate
Digital Viscometers. These instruments provide precise shear profiles necessary to determine viscosity and develop rheological data.
