MCR 702T Rheometer::: Intelligence in Rheometry

One Rheometer. All Possibilities.TMMCR 702 with Twin TechnologyDrive

The rheometry revolution:TAnton Paar introduces a groundbreakinghigh-end rheometer in a classof its own: MCR 702 with Ttechnology.For the first time ever in the history of rheometry,you can perform rheological tests with twotorque transducers and drive units at once, in asingle instrument: Two powerful EC motor units in acombined modular setup – flexible and precise enoughto deliver any result you are looking for.In short, MCR 702 with T is the firstsingle system to cover all possible rheologicalapplications – past, present and future.

T Test ModesEC ModeNow the choice is yours: The EC test modeprovides you with the vast range of applicationoptions that MCR rheometers are known for.In this mode, the lower EC (Electrically Commutated)motor is simply removed and MCR 702 is operated as aCMT (Combined Motor Transducer) rheometer.By using a single air-bearing-supported EC motor unit,you can make the most of the motor’s TruStraincapability and perform ‘classic’ stress-controlled tests.The option to either control the shear rate or the shearstress opens up countless applications specific to singlemotorrheometers. measuring drivingWith the lower motor unit removed, MCR 702 is readyto be equipped with any temperature device and/orapplication-specific accessory you may require. Thereare over 35 options to choose from, all of them readilyrecognized and configured by Toolmaster, MCR 702’sautomatic tool recognition and configuration system.

TComplete Gap ControlIsolign: Nano-scale precisionMCR 702 T is the first rheometer to offernano-scale precision on several counts – such aslow-torque measurements down to a minimum of1 nNm and the control of angular deflections downto 100 nrad.Now this peak precision also extends to the system’smeasuring gap control: The new Isolign Piezo flangeperforms gap size changes as small as 10 nm. Basedon a system of 3 Piezo elements in the flange of themeasuring chamber reception, Isolign is reliablyemployed in all T test modes.Common step-motor-based systems employ a longkinematic chain to translate single motor steps into gapsize changes in the micrometer range. Capable of stepsizes down to 10 nanometers, Isolign is decadesmore precise than any other comparable solution forgap size adjustments in rheological tests.In high-sensitivity tests over long periods of time(e.g. creep, step strain or step shear rate tests oncomplex fluids) and tests across vast temperatureranges, the measuring gap is kept constant withinlower tolerances than ever before.TruGap: Consistent gap controlThe patented TruGap system (US Patent 6,499,336)consistently measures and precisely adjusts MCR 702’smeasuring gap to the desired position independently oftemperature and thermal expansion. Permanent control,documentation and traceability of the actual measuringgap are guaranteed, eliminating the need for regularzero-gap settings.

TA world of optionsTemperature devicesChoose from a wide range of modulartemperature devices tailored to specific rheologicalrequirements – from -150 °C to 1000 °C, fromlow-viscosity liquids to highly elastic solids, fromtraditional rotational tests to DMTA measurements.All systems are easily exchanged, ensuringvirtually gradient-free temperature control for allapplications.Measuring systemsAnton Paar offers a wide range of MCR measuringsystems and continuously develops new customtailoredsolutions. These systems can be used withall temperature devices and are interchangeablewithin their category of accessories. Made fromdiverse materials and featuring different surfacesand dimensions, all systems are optimizedregarding compliance, thermal expansion andthermal conductivity.Toolmaster:Effortless exchangeToolmaster (US Patent 7,275,419) recognizes allmeasuring and environmental systems connectedto the rheometer and accordingly configuresthe entire system accordingly. In the 2EC mode,Toolmaster recognizes any system attached toeither side of MCR 702 via a transponder chipcontaining all relevant data.New paths for your applications:The RheoCompass softwareMCR 702 T calls for a navigation toolthat gives you the complete overview as well asthe exact insights you require: Anton Paar’s newRheoCompass software, the most innovativeand up-to-date rheometer software available onthe market.Designed for intuitive use, RheoCompassenables application-oriented template filtering,customized test and analysis definitions, highlysimplified data retrieval and much more.
