Optical Rheometer for Accurate Viscosity Analysis - Fluidicam RHEO

The Fluidicam RHEO is a unique and innovative optical rheometer that could be used for accurately analyzing viscosity. The instrument may be used even for very liquid samples. A flow visualization in a microfluidic channel is beneficial to rheology determination. The specific benefits of such process includes small sample volume requirements, extremely fast adjustments in temperature, and high shear rate analysis.

Highlights of the Fluidicam Rheo

Highly Accurate Rheometer

The Fluidicam Rheo measures particles while simultaneously comparing them to reference solutions. This method was found to have high precision and reliability. Image acquisition provides a visual control and easy review of the data.

High Shear Rheometry

The instrument operates at high shear rates ranging between 100 to 105 s-1. This allows access to real usage conditions, including spraying, injecting, lubricating, printing, or facilitating a simple pipe flow.

Fast Viscosity Measurement

  • Dynamic viscosity (mPas)
  • Liquid sample analysis
  • Injectability properties
  • Sprayability properties
  • Average Molecular Weight determination

Small Sample Volume

Sample consumption during the measurement is lowered through the aid of small channel dimensions. As such, it is possible to measure viscosity at high shear levels with less than 500 µL.

Applications

  • Home and personal care
  • General chemistry and polymers
  • Food and beverages
  • Pharmaceuticals
  • Oil and petroleum
  • Paints and inks

Key Benefits

Fluidicam RHEO is an easy-to-use instrument that yields high repeatability and precision. Its small sample consumption feature enables multiple experiments to be conducted without the need to re-sample.

Its volatile enclosed system ensures that fast-drying samples be easily characterized. Because it is possible to choose reference solutions, either relative or absolute viscosity may be measured.

A specially-designed heating plate reduces the time required to adjust the temperature. This plate also enables operators to measure viscosities ranging from 4 °C to 80 °C in less than 15 minutes.
