Rheolaser Master is based on optical measurement by MS-DWS. The complexity of polymers and their compounds is a subject to continuous developments. To study these developments this measuring technology is used. Rheolaser was developed for performing passive Microrheology analysis for soft material.


  • It allows automatic plot of particle Mean Square Displacement (MSD) and microrheological parameters of the material such as elasticity, viscosity and relaxation time
  • Rheolaser can also analyze the viscoelastic properties of viscoelastic products.



  • Cosmetic, food, polymer, pharmaceutical, paint and ink industries.

Technically differences:


  • For characterizing viscoelastic fluids, user can plot the viscous and elastic modulus at a chosen frequency (1 Hz for instance) or versus frequencies

  • This method is also used for analysis of the microstructure like mesh size and relaxation time


  • Multiple experiments can be performed with the same sample versus time, as it is a non destructive method

  • Evolution of G’µR, G’’µR, TR µR versus time

  • Measurement of the perfect gel point by plotting G’’µR /G’µR at several frequencies versus time

  • Evolution of the polymer mesh size versus time

  • Evolution of the viscoelastic properties versus the pH, temperature


Structure recovery / thixotropy:

  • After shearing, automatic plot of G’µR ,G’’µR at rest versus time at a one or several frequencies

  • Relaxation time TR UR kinetic

Product Details:

Minimum Order Quantity1 Piece
Maximum Viscosity Range1 to 10,000 mPas
Applicationlab or inline use
Temparature-20 t0 120degC
Response time15ms
Pressure25 bar or more
Power supply230V

QVis viscosimeter is an oscillating quartz which is robust and versatile: with its wear-free crystal QVis can determine the dynamic viscosity of both resting and flowing liquids. Being fully independent of the flow conditions, your liquid can even have turbulences.

  • Available for both inline/process and laboratory applications
  • Measurement of the dynamic viscosity and temperature
  • Simultaneous display of the kinematic viscosity
  • Determination of the viscosity independent of the direction of flow
  • High shear-rates without adverse effects on the test fluid
  • Large measuring range (1 to 10.000 mPas)
  • Only small samples required for measurements (approx. 35 ml)
  • Short set-up and measuring times
  • Easy to handle and to clean
  • Robust quartz sensor without any moving parts
  • Standard digital interface (RS-232) for optional connection to your WINDOWS PC

    Fluidchem- Rheology on CHIP

    New concept of viscosity measurement, which mimics the application of high shear like PROTEINS, POLYMERS, PAINTS, INKS, COSMETICS, etc.

    The method uses a micro fluidic chip, made of PP or glass and simply flow just few µL or ml test sample along with the reference, the instruments takes the pictures of the flow in the chip and provides direct info on viscosity or stress rheology ( up to 10exp5 /sec) in just few seconds. These chips do not require any calibration and can be cleaned for reuse or disposable.
