Visco-PRO

Product Overview

Visco-PRO is a revolutionary viscosity and viscoelasticity measurement system built on patented non-rotational micro-displacement technology. Designed to deliver precise liquid physical property data in under 1 second, it requires less than 50 mL of sample per test, making it one of the most efficient instruments in its class.

Unlike traditional rotational viscometers — such as Brookfield-type instruments — Visco-PRO uses a unique micro-displacement measurement method that contains no rotor. This fundamental design difference eliminates the need for cleaning between samples, reduces cross-contamination risk, and protects shear-sensitive materials from mechanical degradation during testing.

The system excels at characterizing challenging fluid types including non-Newtonian fluids, colloids, emulsions, and polymer solutions. By completing measurements in less than 1 second, Visco-PRO captures the true viscosity of thixotropic and time-dependent materials before their structure has a chance to recover.

With its compact form factor and minimal sample requirements, Visco-PRO is the ideal solution for laboratories working with expensive, scarce, or difficult-to-handle liquid samples across industries ranging from food and pharmaceuticals to paints, cosmetics, and academic research.

Technology / How It Works

At the core of Visco-PRO is a patented non-rotational micro-displacement sensor. Rather than spinning a spindle through a liquid — the approach used by conventional rotational viscometers — Visco-PRO displaces a tiny volume of fluid using a precisely controlled micro-element.

How It Differs from Rotational Viscometers

Traditional Brookfield-type viscometers rely on a rotating spindle immersed in the sample. The torque required to rotate the spindle at a set speed is converted into viscosity. This method introduces mechanical shear that can alter the sample's microstructure, break down flocs, and distort readings for shear-sensitive materials like emulsions, gels, and polymer solutions.

No Rotor, No Shear Degradation

Visco-PRO's rotor-free design means there is no mechanical agitation of the sample. The measurement element gently displaces a micro-volume of fluid, recording resistance without imposing destructive shear forces. This preserves the native structure of the sample and delivers more accurate readings.

Sub-Second Measurement Speed

Completing the entire measurement in under 1 second is critical for time-dependent fluids. Thixotropic materials — such as drilling muds, cosmetic creams, and certain food products — recover their viscosity structure over time. Visco-PRO captures the true viscosity before thixotropic recovery begins, giving researchers and QC engineers an honest snapshot of the material's flow behavior.

Micro-Sample Volume

With a requirement of less than 50 mL per test, Visco-PRO enables viscosity characterization of expensive pharmaceutical formulations, limited-batch chemical samples, and precious academic research materials that would be impractical to test with conventional instruments requiring 100–500 mL.
