Brookfield Viscosity Instruments

High Shear Viscometer Brookfield's CAP-2000+ offers expanded temperature and viscosity ranges with variable speed capability. The CAP2000+ now offers lower shear rates, making it suitable for many applications where small sample volume and good temperature control are necessary. And the rugged, easy-to-use design make it perfect in environments where other instruments won't last.

The Wells-Brookfield Cone/Plate Rheometer is a precise torque meter which is driven at discrete rotational speeds. The torque measuring system, which consists of a calibrated beryllium-copper spring connecting the drive mechanism to a rotating cone, senses the resistance to rotation caused by the presence of sample fluid between the cone and a stationary flat plate. The resistance to the rotation of the cone produces a torque that is proportional to the shear stress in the fluid. This reading is easily converted to absolute centipoise units (mPa s) from pre-calculated range charts. Alternatively, viscosity can be calculated from the known geometric constants of the cone, the rate of rotation, and the stress related torque.
