The first ready to use instrument to characterise the end-use properties of any soft material.
A NEW WAY TO ANALYSE VISCO-ELASTIC PRODUCTS
3 KEY PARAMETERS
Based directly on the MSD curves (Mean Square Displacement), 3 parameters are directly computed in just one-click without any parameters for the user to define.
These parameters are kinetic, meaning the user can monitor the evolution of any product (gelation process, structure recovery after a stres, long term stability, etc...) versus ageing time.
SOLID-LIQUID BALANCE (SLB)
Monitor properties such as: adhesion, spreadability, gel point, shape stability, physical stability, etc...
Using this parameter allows the user to know easily if his product is rather liquid-like or solid-like (how is the gel structure?).
SLB of a polymer system during a change of temperature
ELASTICITY INDEX (EI)
Monitor properties such as: mesh size, hardness, recovery after a shear, etc...
This parameter enables easy comparison of many products in terms of elasticity strength. This value offers a quick and easy ranking of the structure in any studied products, in just one-click.
EI of two different gelatins during cooling of the system
MACROSCOPIC VISCOSITY INDEX (MVI)
Monitor properties such as: effect of a thickening agent, texture, flowability, long-term stability, etc...
Rank your products depending on their macroscopic viscosity at zero-shear in just one-click, and control their stability by monitoring the evolution of this parameter versus ageing time.
MVI of three emulsions stabilised by different thickeners
For the experts in rheology and DWS, it is possible to compute physical parameters such as the elastic and viscous moduli (G' and G''), relaxation time (tR), macroscopic viscosity at zero-shear, diffusion coefficent, mesh size, and many others...

END-USE PROPERTIES ANALYSER
Rheolaser™ is dedicated to formulators interested in the end-use properties of their products.
|aaaaaaaaaaaaaa& many others...|
It is designed to answer to the following questions:.
- What is the effect on the product properties is I change the polymer type / concentration / molecular weight ?
- Will it stick (to the hand, to another product, ...) ?
- Will it spread easily ?
- Will it keep its shape ?
- Will it be stable ?
- Will it flow ?
- And many more...
