The flow-out cup is still an important measuring instrument for determining the consistency of liquids in the laboratory and in production simply and quickly. However, they are only suitable for low-viscosity liquids, but not for high-viscosity substances such as slurries, etc. Accurate results are obtained in liquids with Newtonian behavior. Usually, the spout cup itself is made of anodized aluminum, while the nozzle is usually made of stainless steel. Based on DIN 53 211

* Negotiate the level with the level
*Place the Viscosity Cup on a lab rack or in a thermostatic bath
*Close the mouthpiece
* Fill with fluid
*Scrape the glass plate along the edge of the Viscosity Cup to scrape off excess fluid and cover the glass plate over the Viscosity Cup.
* Open the nozzle
*Remove the glass plate horizontally and start the stopwatch at the same time.
* When the flow of fluid is interrupted for the first time, stop the stopwatch timer and record the time.
Details are provided in each standard. Note: The Viscosity Cup is only calibrated within the specified range and at the specified time.
