Cannon-Ubbelohde Viscometer

Brand: Ramin' USA Product Code:
VIS-CUB

This is a suspended level design very similar to Ubbelohde Viscometer except for a different geometry at the top for the air venting passage which makes this design somewhat durable. Operationally, it is the same as the Ubbelohde, but the values of the constants and exact measuring ranges are slightly different. Each tube has a permanent serial number and is supplied with a calibration certificate which bears the official Constant for that tube. When the drop time of the sample is determined (average repetitive timings), the value in seconds is multiplied by the constant to obtain the viscosity of the sample in Centistokes (cSt).
