Manual Glass Viscometers

We offer a variety of glass capillary viscometers because no single viscometer is ideally suited to every application. Use of high quality instruments ensures test reliability and accuracy

Transparent

For transparent/translucent liquids

Suspended Level

For transparent/translucent liquids. Ideal for testing at multiple temperatures because they have the same viscometer constant at all temperatures.

Dilution

For dilution of polymer solutions to provide an estimate of the molecular size and shape.

Reverse Flow

For transparent and opaque liquids. Must be cleaned, dried and refilled between repeat determinations.

Vacuum

A special type of reverse-flow viscometer for highly viscous samples (transparent or opaque). Accurately controlled vacuum is required to pull the liquid through the viscometer.
