Brookfield DVNext Cone/Plate Rheometer, HA, Magnetic, Point/Jewel, Compliant

The DVNext Wells-Brookfield Cone/Plate Rheometer is a cutting-edge instrument designed for precise and reliable measurement of absolute viscosity and detailed rheological properties. Ideal for research, quality control, and product development applications, it delivers accurate data using small fluid sample volumes, making it an excellent choice for laboratories with limited sample availability or high-value materials.

Key Features & Benefits

Small Sample Volume:

 Efficiently measure absolute viscosity with sample sizes as small as 0.5 to 2.0 mL, depending on the cone spindle used. This is ideal for applications where minimizing material usage is critical.

Advanced Cone and Plate Design:

The unique cone-and-plate geometry provides precise control over shear rates, offering highly accurate rheological data for analyzing material flow behavior. This design ensures consistent, repeatable results for even the most detailed research.

Temperature Precision:

 The integrated sample cup features a jacketed design that connects to a constant temperature bath, enabling precise temperature control from 0°C to 100°C. This ensures accurate viscosity measurements by maintaining stable testing conditions and supporting temperature-sensitive materials.

User-Friendly Setup:

Alignment of the cone and plate is straightforward with a simple mechanical procedure, requiring no external tools. The removable sample cup allows for quick filling and cleaning without recalibration.

Advanced Functionality:

• Electronic Gap Adjustment: Simplifies setup and ensures consistent sample measurement thickness for improved workflow.
• Auto-Zero and Auto-Range Functions: Enable precise torque measurements and automatically determine the full-scale range for all spindle and speed combinations.
• Highly Accurate Measurements: Torque accuracy is within ±1% of the full-scale range, with exceptional repeatability of ±0.2%.

Versatile Spindle Options:

The rheometer comes with one pre-calibrated CPA spindle, but additional spindles can be purchased and calibrated for use with the same sample cup. This flexibility allows the system to be tailored for different viscosity ranges and testing needs.

Rugged Build and Portability:

The instrument comes with a durable lab stand (Model G), as well as a carrying case for easy transport, making it suitable for both laboratory and field use.

How It Works

The DVNext operates as a precise torque meter, driven at controlled rotational speeds. The system measures the resistance of a fluid sample placed between a rotating cone and a stationary plate. This resistance generates torque, which is directly proportional to the fluid's shear stress. The shear rate is determined by the cone's geometry and rotational speed, allowing the viscosity (mPa·s) to be calculated accurately.

With its advanced measurement capabilities, the rheometer provides unparalleled insights into the flow properties of various materials, including creams, oils, gels, resins, and other complex fluids.

Applications

The DVNext Wells-Brookfield Cone/Plate Rheometer is suitable for a wide range of industries, including:

• Pharmaceuticals: Testing ointments, creams, and syrups for consistency.
• Cosmetics: Analyzing the texture and flow of lotions, gels, and skincare products.
• Food & Beverage: Measuring viscosity of sauces, dressings, and syrups.
• Chemicals & Coatings: Evaluating resins, adhesives, and paints for quality control.
• Petrochemicals: Testing lubricants and oils for performance reliability.
