Anton-Paar Physica MCR 501____________________________________
This rheometer performs a wide range of steady and dynamic tests in both Control Sheear Rate and Control Shear Strain mode. From generating simple flow curves to the dynamic analysis of complex fluids, melts, and co-polymers, this rheometer offers simple programming and test setup. This equipment can be used to run different types of analysis such as Creep and recovery, Normal force, Stress relaxation, Linear tensile and compression, including tack, Amplitude sweep, Frequency sweep, Temperature sweep, Time sweep, Multiwave, Oscillation with superimposed rotation or any combination of the above.(http://www.anton-paar.com) |

_________________________Advanced Rheometric Expansion System
 |
The Advanced Rheometric Expansion System (or ARES) is a rheometer (mechanical spectrometer) that is capable of subjecting a sample to either a dynamic (sinusoidal) or steady (linear) shear strain (deformation), then measuring the resultant torque expended by the sample in response to the strain. Through this instrument, the rheological properties can be measured. Strain is applied by motor, and a transducer measures the resulting torque. This is truly one of the best rheometers in the world and only one at Iowa State University. |
Optical Shearing System_________________________________________
| The Cambridge Shearing System (CSS) has been developed in collaboration with the Department of Chemical Engineering at Cambridge University. It is designed to fit on any standard upright microscope and has a temperature range of ambient to 450C. The entire system is driven from a Windows program running on a PC. The system can work in three modes: steady velocity, step movement at constant velocity and an oscillatory motion with constant frequency and amplitude. The shear rate may also be set separately. The temperature may be programmed with up to nine ramps. The main advantage of this system is that the changes occurring in the sample as it is sheared can be visually observed through the microscope or on the PC through a video capture card. |

_________________________Advanced Capillary Extrusion Rheometer
 |
The RH 7 Flowmaster is an advanced, and powerful floor standing capillary rheometers suitable for research and product development.
The Rosand RH7 has set new standards in research level capillary rheometryand is used in several hundred research laboratories around the world for a range of applications including polymers, foods, coatings and ceramics. Bohlin Instruments has continuously developed the original RH7 design and its operating software to produce a new generation of floor standing capillary units with market leading performance characteristics and capabilities. The RH7-D retains much of the robust 'H' frame design principle, which lies at the heart of the instruments' ability to operate under high loading conditions. |
Capillary Break-up Extensional Rheometer__________________________
Materials that behave similarly in a shearing flow often behave very differently in an extensional flow. The unique HAAKE CaBER 1 rheometer provides valuable information about the material's extensional properties that rotational rheometers simply cannot provide. With the CaBER 1, stringiness, filament breakup-time and extensional viscosity can be quantified to quickly optimize fluid formulations. |
