Frequently Asked Questions
1. What is the benefit of using an Ubbelohde viscometer?
The Ubbelohde design allows for measurement regardless of the exact liquid volume in the reservoir, making it one of the most accurate and reliable manual capillary methods.
2. How do I choose between a brass or V2A flow nozzle?
V2A stainless steel (found in the Fritz original Frikmar cups) offers superior chemical resistance, while brass is a standard choice for less corrosive industrial liquids.
3. Do Industrial Physics cups comply with international standards?
Yes, many of our aluminum viscosity cups are manufactured to meet DIN 53211 standards, ensuring your results are internationally comparable.
4. Do I need a timer to use a manual viscometer?
Yes, manual viscometers like the Ubbelohde or flow cups require a high-precision digital timer to record the "efflux time" needed to calculate viscosity.
