Description:

• Rapid Determination of Absolute Viscosity for Small SamplesThe Wells-Brookfield Cone/Plate Viscometer/Rheometer 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/Rheometer 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/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 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/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. 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/Rheometers. These instruments provide precise shear profiles necessary to determine viscosity and develop rheological data.

Features & Benefits:

• Determine absolute viscosity of small samples (0.5 - 2.0 mL)
• Precise shear rates for determining a material's flow curve behavior

Any test sample requiring absolute viscosity measurement under totally enclosed conditions is a viable candidate.

 

Features & Benefits:

• Portable site-to-site mobility with 1' x 1' x 2' instrument footprint
• Rheovision software for automation and control of all test parameters
• Designed to operate in severe environments with Hastelloy cups and bobs standard
• Quick and easy to operate
• Measures samples from vacuum to high pressure of up to 1000 psi
• Safety relief valve included
• Robust motor capable of speeds up to 1000 RPM
• Outside cylinder rotates at shear rates up to 1700 sec-1, spindle inside remains stationary
• Available with triple annulus geometry for increased sensitivity when measuring low viscosity fluids
• Quick and easy setup
• Complete with choice of spindle (bob), cup, Rheovision
• Software and computer
• Industrial standards

 

Measures under temperature conditions: -40°C to +260°C

• RTD temperature sensor on the inner cylinder surface insures accurate sample temperature
• Runs test to API industry standard
• LSRV measurements to 0.2 sec-1

Simulation of In-Process conditions:

• Down Hole
• Cooking
• Blending
• Reactors

 

Principle of Operation:

• The outer cylinder (sample cup) is driven by a stepper motor at speeds from 0.05 RPM to 1000 RPM. The inner cylinder (bob) contains an RTD probe on the surface to provide temperature measurement where the shear stress is being measured. Several cup and bob designs with different geometries are available to suit various applications.
• The unique torque tube design enables the instrument to respond to minute changes in viscosity, mechanically transmitting a rotational torque signal out of the pressure containment area without friction. Thus all electronics, bearings, and other sensitive components are completely protected from the influences of both the sample fluid and its vapor.
