Small Sample Viscometer VISCOlab 4000

small sample viscometer

The Cambridge Viscosity VISCOlab 4000 shares the same sensor as the VISCOlab 450, but with advanced electronics and software that enable significant additional versatility and capabilities. While the VISCOlab 450 is designed for single-range requirements, the VISCOlab 4000 is a small sample viscometer that is much more flexible—supporting up to 12 different 20:1 viscosity ranges—and offers more output options. Like the 450, this unit requires less than 1.5 ml of sample and produces an extremely reliable viscosity measurement.

Because of its innovative oscillating piston design, the VISCOlab 4000 measures fluids in all viscosity ranges at ambient temperatures, assuring consistent and repeatable viscosity measurements. An optional jacket is available for temperature control with a re-circulating bath, enabling accurate viscosity measurements from -40°C to +110°C. In addition to the sensor, sophisticated electronics provides users with substantial flexibility, including specifying temperature and viscosity display units, the data averaging interval, and control characteristics. Optional real-time density measurement enables real-time kinematic viscosity readings in addition to the system’s standard absolute viscosity measurements. The VISCOlab 4000 incorporates a serial interface to make it easy to output data to a PC or an optional thermal printer.

Easy to use, easy to clean, easy to own, the VISCOlab 4000 is a highly accurate, robust and reliable small sample viscometer.
