  • The rheometry is driven by an Electrically Commutated (EC) motor which is supported by two air bearings (radial and axial) for improved torque control
  • Torque
  • - Min: 1 nN m (rotation), 0.5 nN m (oscillation); Max: 200 mN m; resolution: 0.1 nN m
  • Angular deflection: 0.05 μ rad to ∞
  • Angular velocity: 10-9to 314 rad/ s
  • Angular frequency: 10-7 to 628 rad/ s
  • Normal force: 5 mN to 50 N; resolution: 0.5 mN
  • Temperature control
  • -Peltier system with counter cooling forbottom plate and hood to cover top plate to give good thermal stability
  • - Operating temperature range -20 oC to +200 oC;resolution: 0.01 oC.
  • -Air circulation control through the hood for additional thermal stability
  • Modular design of the rheometer for easily assembling the peltier plate and geometry for: standard rheological as well as dielectro, opto and magneto rheological studies
  • Additional control ports:
  • - Auxillary input (2 ports) for reading external devices and relays
  • - Analog output (4 ports) to trigger external devices
  • - Provision to read temperature with a thermocouple
  • Dielectro-rheology
  • • Peltier temperature control module; operating temperature range: -20 oC to +200 oC with a resolution of 0.01 oC.
  • • BNC connection to apply electric field to bottom plate (peltier plate)
  • • Spring attachment with BNC connection to apply electric field to top plate (geometry)
  • -the spring connector facilitates continuous contact with the top plate, during rotation or oscillatory movement of the plate.
  • • LCR Meter (Agilent, E4980A)to apply the probing electric field and study the capacitance, resistance, conductance and impedance characteristics of the sample
  • - Voltage: 20 V max (ac); Frequency: 20 Hz to 2 MHz; DC bias: 20 V max

  • • Power supply to generate magnetic field; max current: 5A
  • • Specialized fluid circulator hoses to handle the high temperature during magnetic field generation
  • • Available geometries (top plates); parallel plate:
  • Rheology of low viscous samples
  • • Peltier module with provision to insert concentric cylinders
  • • Double gap geometry, i.e. flat top plate inserted within a cup;
  • - 27 mm dia (inner plate); stainless steel
  • • For samples with viscosity as low as ~ 1 mPa. s (i.e. comparable to viscosity of water at ambient temperature)
  • Can be operated in both stress (torque) controlled and strain (displacement) controlled modes
  • Oscillatory rheology:
  • -strain dependence; frequency dependence; time dependence
  • Creep test; temperature ramp
  • Steady state rheology:
  • -continuous shear ramp, time dependent flow behavior, yield stress measurement, temperature ramp
  • Concentric cylindrical geometry for very low viscous liquids (viscosity as low as water)
  • Dielectro-rheology
  • Opto-rheology
  • Magneto-rheology.
