Measure the fluidity of your liquids accurately with the viscosity cup
The viscosity cup is an essential tool for measuring the fluidity of a liquid by determining its flow time through a calibrated orifice. Used in the coatings, ink, cosmetics, and lubricant industries, it is used to assess the consistency and compliance of products with required viscosity standards.
Easy to use and offering fast results, the viscosity cup is an essential tool for quality control and optimization of industrial formulations.
How does viscosity cutting work?
The viscosity cup is based on a simple principle: measuring the time it takes for a liquid to flow through a calibrated orifice under the effect of gravity. Its use takes place in several stages:
- Filling the cup – The liquid is poured up to the maximum level provided by the instrument.
- Flow Trigger – The orifice is open, allowing liquid to flow freely.
- Flow time timing – Measurement starts upon opening and stops when flow becomes discontinuous.
- Interpretation of results – The flow time is compared to reference values to determine the viscosity of the liquid.
The choice of cutting model depends on the viscosity of the liquid analyzed and the standards applicable in the sector concerned.
Technical characteristics of the viscosity cup
The viscosity cup is available in several models and materials adapted to the requirements of different industries:
- Standards and references : DIN, ISO, Ford, Zahn, Shell, AFNOR, each cut having specific dimensions and holes.
- Materials : Aluminum, stainless steel or plastic, depending on the required chemical resistance.
- Hole diameter : Varies by model, generally between 1.5 mm and 8 mm.
- Measurable viscosity range : Typically between 10 and 1,000 centistokes (cSt).
- Measurement accuracy : Expressed in seconds, with a small margin of error when used under controlled conditions.
- Measurement temperature : Directly influences the results, sometimes requiring thermal control.
Each cut is calibrated according to specific standards, guaranteeing the repeatability and reliability of measurements.
For which matrices is the viscosity cup suitable?
The viscosity cup is particularly effective for analyzing a wide range of liquids, including:
