ZAHN viscosity Cup for fluids

The ZAHN viscosity cup determines viscosity by measuring the time it takes for a fixed volume of fluid to flow out through a small hole at the bottom of the cup. It is used to quickly assess the fluidity of liquids in industries such as coatings and inks. Applications include on-site quality control and production process monitoring.
Selection
When selecting, consider the viscosity range of the fluid being measured and match it with the corresponding cup number. Choose stainless steel or plastic material based on the testing accuracy requirements. Pay attention to the influence of cup nozzle size on measurement results, and perform regular calibration to ensure data reliability.

This article introduces how a cone-plate viscometer measures the rheological curve of UV ink. UV ink is a non-Newtonian fluid whose viscosity changes with shear rate.
Handheld viscosity cups are used for rapid assessment of paint viscosity at construction sites.
A handheld viscosity cup is a portable tool used to quickly assess the viscosity of coatings at construction sites. It operates based on the flow-out time method, calculating viscosity by measuring the time it takes for the coating to flow out of the cup's orifice. It is suitable for Newtonian or approximately Newtonian fluids.

Key steps for measuring the efflux time of varnish using a viscosity cup method
This article introduces the method for measuring the outflow time of varnish using a viscosity cup. The principle is based on Poiseuille's law, where viscosity is estimated by recording the time it takes for the liquid to completely flow out from the small hole at the bottom of the cup—longer times typically indicate higher viscosity.
Application of Laboratory Coating Machines in the Preparation of Lithium Battery Electrodes
As a key device for achieving uniform coating of active material slurries onto current collectors, the application of laboratory coating machines directly influences the areal density consistency, thickness uniformity, and microstructure formation of electrodes, thereby affecting the energy density, cycle life, and safety of batteries.
The difference between a wire bar coater and a gap-type wet film applicator.
The wire-wound drawdown bar directly quantifies the coating through the gap between wires, making it suitable for thin coating preparation with high precision, particularly for low-viscosity fluids. In contrast, the gap-type wet film applicator indirectly controls film thickness through the groove depth, with the actual coating thickness significantly influenced by material properties, making it more suitable for high-viscosity coatings and thick film preparation.
Types and Selection of Paint Viscosity Cups
As a simple tool for measuring the liquid outflow time, the viscosity cup is mainly categorized into various types such as the Tu-4 cup, ISO cup, Ford cup, and Zahn cup, based on standards from different countries and regions. These cups differ in orifice size, capacity, and the types of fluids they are suitable for.
