hts-VROC® Viscometer - High Temperature Viscosity

Because viscosity is heavily dependent on temperature, all RheoSense viscometers come with the option of adding temperature control. Different applications may require high temperature viscosity analysis for instance, the oil/lubricant industry. When working with lubricants, specific shear rates and temperature ranges have to be tested to mimic the conditions in which the lubricants will actually perform in such as in the bearings of internal combustion engines.

To meet this requirement, RheoSense introduced the hts-VROC® model. This system provides the same features and specifications as m-VROC®, but hts-VROC® provides the added capability to measure at temperatures as high as 105°C.

Applications: hts-VROC® Viscometer - High Temperature Viscosity
hts-VROC provides extensional viscosity data by monitoring the sample flow through a microfluidic channel. The system measures the change in pressure using the MEMS pressure sensors, and it registers changes in the flow.
Applications include:
  • Polymers
  • Fiber extrusion spinnerets
  • Paint rolling
  • Blow molding
      • Ink jet printer nozzles
      • Sheet or film drawing
      • Flow through a porous media
