The Bohlin CVO rheometer is a flexible rheometer system suitable for research, product development and quality control.

Since its formation, Malvern has been innovative in developing state of the art rheometer systems.

Renowned for their accuracy, quality and ease of use, the Bohlin VOR, Gemini and DSR rheometers have all set new standards in instrument performance. Following in this tradition, the CVO Rheometer is one of Bohlin's most flexible and versatile rheometer systems to date.

Encased within a spill resistant cover with an integral touchpad, the CVO rheometer constitutes a compact unit which is impervious to dirt and fluids.

From the outset, the CVO rheometer has been designed to be easily configured to suit varying rheological testing requirements.

Interchangeable temperature control units ensure that the CVO rheometer can test all sample types, from low viscosity solutions to polymers melts.

Simple, easy to use MS-Windows based operating software allows complete flexibility in programming complex or more basic rheological test protocols.
