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.


Features:

  • 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.


Applications:

 

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


Technically differences:


Evaluation:


  • 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


Evolution:


  • 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

Reynold No80000
Temp-10 degC to 100degC
Pressure0 to 35 bar
Line dia3mm, 5mm
sample volume0.5L to 3L

Turbulance Rheometer is used for Quality control of Drag Reducing Agents with the Turbulence Rheometer

  • Compact laboratory plant
  • Different Reynolds numbers can be analyzed in one test run
  • Minimal shear forces, no edges, constant acceleration
  • Different capillary length and diameters usable
  • Adaptation to customer requirements possible

The sample is pumped through a test capillary with small diameter. This enables test conditions with variable flow rates and in a wide range of Reynolds numbers


Applications

  • Testing the efficiency of Drag Reducing Agents (DRA)
  • Optimizing Drag Reducing Agents
  • Quality control

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.
