Viscosity Flow Cup ZAHN

The Zahn viscosity flow cup is a practical and user-friendly tool designed to measure the viscosity of liquids such as paints, inks, varnishes, lacquers, and other coatings. Its immersion design with a long-handle loop allows for quick and direct testing of fluidity during production or formulation processes.

Main Application

This type of viscosity flow cup is used to perform relative viscosity measurements based on the time it takes for a liquid to flow through a calibrated orifice. Results are typically expressed in seconds and serve as a useful reference for adjusting products either during manufacturing or prior to application.

Why is Viscosity Control Important?

• Optimize application methods (spray gun, brush, roller, etc.).
• Prevent issues like dripping, poor coverage, or drying defects.
• Ensure consistent product quality.
• Adapt formulations to temperature changes or application techniques.

During formulation, it is also essential to evaluate viscosity under different shear rates and assess the product’s thixotropy, which helps prevent undesirable behaviors during use.

Key Features of Our Zahn Cups

• Made from chrome-plated steel – robust and durable.
• Available in 5 models, covering a range from 5 to 180 centistokes.
• Fitted with a long loop handle for safe and easy immersion.
• Designed for direct use in production or quality control settings.
• Measures kinematic viscosity (ratio of absolute viscosity to fluid density).

Example: If two liquids have the same absolute viscosity but different densities, the denser liquid will flow faster, indicating a lower kinematic viscosity.

Optional: ENAC Calibration Certificate

For greater accuracy and traceability, you can request your Zahn Viscosity Flow Cup with an ENAC Calibration Certificate.

Ideal For
