BF35 VISCOMETER
The BF35 maintains a constant shear rate and is an accurate and versatile tool for drilling fluid measurements.
The BF35 operates on a different measurement technique than traditional standard Brookfield Viscometers. The sample is placed in the cup and the spindle/chamber combination is then immersed into the sample. When the motor is turned on, the chamber rotates while the spindle remains stationary. When the dial reading becomes stable, the torque reading is recorded and manually converted into a viscosity value in centipoise.

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, lure fitting, and embedded temperature probe available.
Electronic Gap
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 micrometre 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.

FALLING BALL VISCOMETER
The Falling Ball Viscometer uses the simple, but precise, Höppler principle to measure the viscosity Newtonian fluids by measuring the time required for a ball to fall under gravity through a sample-filled tube.
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:
KF30 has a fixed angle of 80° and complies with DIN 53015
KF40 can be angled at 50°, 60°, 70° and 80°.
