VROC, Rectangular Slit Viscometer

VROC® technology offers powerful advantages over conventional viscometers and rheometers. This solution features: 

  • 100 µL of sample
  • A remarkably wide dynamic viscosity range
  • Exceptional high and low shear rates 
  • Automated testing for rapid results
  • Prevents film forming, evaporation, and contamination
  • Measures both Newtonian and non-Newtonian fluids easily 
  • Small footprint 
  • Delvers extraordinary precision and accuracy


This technology is housed within a rugged, portable case with a rechargeable, long-life battery that is ideal for remote field measurements where space may be limited and conditions may be difficult. 

Designed to use disposable pipettes, reducing the risk of sample contamination, users can operate it within one minute with almost no training. 

The measurement method, also known as the 
rectangular slit method, provides highly accurate dynamic viscosity data and kinematic viscosity in order to compare with industry standards like ASTM, ISO, SAE, etc. This is accomplished using the innovative microVISC-m™ firmware which utilizes ASTM D341 temperature compensation principles to provide viscosity data at reference temperatures that are different from the actual measurement temperature. This gives the user the ability to compare a sample viscosity at 40° C, 50° C and 100° C in a single measurement.
