My milk kefir, which I think is on the thin side, takes about 13 seconds in this No. 2 cup. The No. 3 cup was to fast for accurate measurements.

It is the price of ONLY ONE cup. But you can choose from #1 to #5. Thanks for your question. **Q: What oil/solvent is recommended to calibrate the #3 cup?** A: As far as I know there isn't a way to calibrate the cup, I never had much luck with getting the same reading consistently or at all for that matter, I ended up buying a digital viscometer, but I haven't used it yet either. **Q: Does this come with a calibration certificate traceable to nist? if so, can i see a sample of the certificate?** A: Hey Ashley,I do not recall if this zahn cup came with a certificate or not. We calibrate our production cups one per year and this is a non production, specialty use cup for items of interests. Cory **Q: WHich Zahn cup would we use to measure water soluble dye?** A: We want to know which water-soluble dye you want to measure. If their viscosity is similar to varnish, you can use No. 2 and No. 3 viscosity cups. If you have any other questions, please feel free to contact us. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Well For My Kefir Making *by J***V on October 19, 2025* I use this cup for kefir making.
