Product catalog summary
Overview
Viscosity Cups, Models 243, are essential tools for measuring the viscosity of fluids in laboratories and production settings. They are suitable for low-viscosity fluids and provide accurate results for fluids that comply with Newton's Law.

Design and Materials
The cups are made from anodised aluminium with stainless steel nozzles, except for the low-cost Model 243/I, which is made from Phenol resin. The design includes a hollow cylinder with a nozzle at the bottom and a gutter channel for excess fluid.

Measuring Principle
Viscosity is measured by timing the flow of a controlled volume of fluid through the nozzle. The process requires precise temperature control of both the fluid and the cup to ensure accurate results.

Test Procedure
  • Level the stand using a spirit level.
  • Place the cup in the stand or temperature control jacket.
  • Close the nozzle and fill the cup with fluid.
  • Wipe off excess fluid and close the cup with a glass plate.
  • Open the nozzle, remove the glass plate, and start the stopwatch.
  • Stop the stopwatch at the first break in fluid flow and record the time.
Temperature control is crucial for reproducible results.

Care and Maintenance
After use, clean the flow cup and nozzle carefully to avoid altering the nozzle size, which would affect accuracy.

Specifications and Models
Various models are available with different nozzle diameters and measuring ranges. Each model is calibrated according to specific standards, such as ASTM D 1200 and ISO 2431.

Accessories
  • Stand with spirit level
  • Temperature control jacket
  • Thermometer (DIN 12 755)
  • Digital stopwatch with calibration certificate
  • Viscosity nomogram and ViscoSoft® 460-FC software for viscosity conversion

Ordering Information
Detailed ordering information is provided for each model and accessory, including nozzle diameters and order numbers.

Technical Description Model 243-2

Viscosity Cups remain the most important quick and simple method to measure the consistency of fluids in the laboratory and in production. Viscosity Cups are, however, only suitable for lower viscosities and not for highly viscous substances such as pastes, etc.. The most accurate results are achieved with fluids within the range complying with Newton’s Law. Viscosity Cups consist of a hollow cylinder which terminate in a nozzle in the bottom. Excess fluid is collected in a gutter channel. In general, the Viscosity Cups are made of anodised aluminium and the nozzles of stainless steel. Only the...
