The ViscoLab 3000 laboratory viscometer is the ideal choice for measurement  when viscosity testing requires the sample material to be tested at specific  temperatures. This lab viscometer is used for applications  ranging from research and development through quality control, and industries  ranging from life sciences to oil analysis, including measuring oil viscosity  for VI (Viscosity Index).  It is a temperature controlled viscometer incorporating an integrated heater  that delivers accurate measurements at user-defined temperatures from slightly  above ambient to 356°F (180°C). The  temperature range of this viscometer can be extended to -40°C with the optional  cooling jacket coupled with an appropriate cooling bath.
Utilizing minimal bench space and  providing an easy to read digital display in centipoise or centistokes, the ViscoLab 3000 delivers accurate measurements with a small sample size; less  than 2ml of fluid is required.
