Thistle Tube Analytical Ferrography

In-wear debris analysis that lets you know where the wear part is, how serious it is and what lead to the abrasive wear.

LogicOil’s Thistle Tube Analytical Ferrography is a complete analytical system for the separation and interpretation of wear and contaminant particles in used lubricant oils, hydraulic fluids, coolants and fuels.

Using thistle liquid lines the oil sample falls down under its own weight reaching the ferrogram surface where particles are septarated on the ferrogram surface.

A microscope is then used to examine the ferrograms. Equipped with both reflected (red) and transmitted (green) light sources to illuminate the ferrogram from both above and below, metal particles which reflect light appear bright red and nonmetallic particles appear green.

Through analytical ferrography wear debris analysis, we are able to interpret basic information about where the wear is, how serious it may be and what may have lead to the abrasive wear.

Application

  • ASTM D7684 Standard Guide for Microscopic Characterization of Particles from In-Service Lubricants.
  • ASTM D7690 Standard Practice for Microscopic Characterization of Particles from In-Service Lubricants by Analytical Ferrography”.
  • Ferrography assists in the diagnosis of the origin, characteristics, and distribution of wear particle debris.
  • Efficient separation of wear and contaminant particles from fluid samples.
  • Rapid preparation of ferrogram.
  • No deformation of particles.
  • Separates particles up to 800µmin size.
  • Easy to operate.

Application

The LogicOil Thistle Tube analytical ferrography instrument can be applied to monitor the oil quality and temperature of lubricating oil, hydraulic oil, gear oil, engine oil, fuel oil, insulating oil, turbine oil, synthetic ester and various other kinds of light and heavy oil. The instrument is also ideal for use as a research tool for tribology and wear analysis in universities, oil analysis lab, and scientific research institutes.
