Sobo LF calibration in washer systems

We have devised a simple working method for the calibration of Sobo LF in operating washer systems based upon refractrometry.

Based on our laboratory findings using a series of dilutions of Sobo LF, we would suggest maintenance levels based upon refractive index are:

  • 4% solution − contribution from Sobo LF > 0.5% Brix
  • 5% solution − contribution from Sobo LF > 0.6% Brix


Sampling of the machine holding tank would be critical due to the sensitivity required. Refractometry also needs to be carried out carefully at constant temperature and with attention to cleanliness in order to obtain meaningful results.
