The Vilastic-3 Viscoelesticity Analyzer

VILASTIC-3 Viscoelasticity Analyzer

Explore the properties of your bio-fluid by measuring both the viscosity and elasticity over a wide range of values of frequency, shear stress, shear rate and shear strain.

Rapid sample change with minimal possible contact between the fluid and operator.

The Vilastic-3 provides the extreme sensitivity and sample handling required for measuring fundamental viscoelastic properties of biological fluids under exquisitely controlled frequency, stress, strain, shear rate, time, and temperature. Once you select a measurement protocol, you can repeat it at any time with high precision because the unvarying geometry of the VILASTIC-3 eliminates the mechanical adjustments and dimensional inaccuracies of traditional rotational instruments.

Computer controlled protocols and data processing mean precisely timed measurement sequences, high volume of measurements and disk storage of all results

Uses water as calibration fluid, a universal standard readily available at no cost

FEATURES

Small sample volume and easy sample handling
Fixed tube geometry provides superior reproducibility
Resident temperature sensor and clock provide record of thermal conditions and time of measurement
Printed data tables together with screen and printer graphics give instantaneous visual presentation of results and hard copy suitable for publication
All measurements are subjected to diagnostics for proper instrument operation
Each measurement produces 29 parameters for rheological functions, pressure-to-flow relations, energy storage and loss, and thermal conditions
ASCII files can be produced for moving selected data into third party spreadsheet and graphics software for further analysis
