Vilastic V-E SYSTEM 美国VilasticScientific

A unique instrument with the ability to perform precise measurements
of viscosity and elasticity of ultra thin fluids–the consistency of water–as well as
thicker fluids.

cheap bandage dresses, Small footprint, small sample size, controlled
thermal environment and portability all add versatility and power to this instrument.

Use the V-E SYSTEM to explore the properties of your liquid by measuring both the viscosity and elasticity over a wide range of values of frequency, shear stress, shear rate, shear strain, 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 V-E SYSTEM 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.

FEATURES

• Uses water as calibration fluid, a universal standard readily available at no cost
• Fixed tube sample 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
