The
Turbiscan LAb
is
the new generation of instruments in the TurbiScan range.
This instrument, existing in three versions, features new performances
to characterize
concentrated dispersions without dilution.
This is a perfect tool for formulation help, analysis and quality control
purposes.
Operates on emulsions,
suspensions and foams
- Up to 60 % v/v concentrated
- From 0.1 µm to 1 mm particle size

Turbiscan LAb
offers
the possibility to carry out a measurement at one point in order to
give, a rapid signature
(sample fingerprint) of the product being analyzed.
Immediate quality control, without dilution of the concentrated dispersions,
is therefore possible,
ensuring that the product meets the required specifications in terms of
particle size and/or concentration.

The
Turbiscan LAb reading head
acquires transmission and data every backscattering 40 µm while moving along the 55 mm cell height. The acquisition along the product is then repeated with a programmable frequency to obtain a superimposition of product profiles characterizing, whether they are identical or not, the stability or instability of the product. The Turbiscan LAb range comes complete with an integral Bar Code Reader and thermo-regulation allowing measurements to be carried out at controlled temperatures, from +5 °C above the ambient to +60 °C. |

Optimization of the dispersion and shelf life study
The
Turbiscan LAb
offers the possibility to accelerate and document ageing tests.
In this regard, variations in particle size due to coalescence or flocculation
can be monitored via the kinetics giving changes of the particle mean diameter
over time. Migrations of the particles leading to sedimentation or creaming
are analyzed by direct and easy calculation of the migration velocity and
the thickness of the
sediment or cream phases.

| The
Turbiscan LAb reading head acquires and backscattering
data at a chosen position on the sample cell. Measured data can be seen on the TurbiScan Lab visual display and stored on the PC though to the software. It offers the possibility to carry out a measurement at one point in order to give a rapid signature (sample fingerprint) of the product being analyzed. Immediate quality control, without dilution of the concentrated dispersions, is therefore possible, ensuring that the product meets the required specifications in terms of particle size and/or concentration. |
