Omnitek U-Visc Automatic Viscometry System

Descriptions

The Omnitek U-Visc is the next generation of completely automatic viscometry systems. The system combines several unique features, making it the instrument of choice in many applications, ranging from QC to R&D to used oil analysis. While offering full compliance with ASTM D445/D446, the specially designed viscometer tubes cover a 100-fold range, e.g. from 1 to 100 mm2/s. The tubes are based on the well-known and proven Ubbelohde design, but only require 8-16 mL of sample and approx. 12-15 mL of solvent for cleaning. 

Features

  • Applicable for fuels, base oils, formulated oils, and other petrochemical fluids as well as diluted polymers
  • Meets all ASTM, EN, ISO, and DIN standards related to kinematic viscosity and diluted solution viscosity 
  • Extremely accurate temperature control
  • Extremely accurate flow-time measurement independent of fluid type
  • Viscometer filling by either vacuum or pressure method
  • Little sample volume / little solvent consumption
  • High Capacity; up to 10 measurements per bath per tube per hour
  • Innovating viscometer tube cleaning allowing cross contamination free operation
  • Easy viscometer tube exchange
  • Suitable for petrochemical fluids and diluted solution viscosity samples
  • Chemically resistant to an extended range of fluids and solvents
  • Multiple versions available covering a wide variety of requirements
  • Compact design
