Modern lubrication oils are designed to hold a certain amount of water in suspension, when this level is exceeded the water becomes FREE and separates from the oil, typically new lubrication
oils have a value of >500ppm. Bio-degradable oils generally have a higher level of water retention capability. Pure base oils have very limited solubility, which is related to the ratios
of paraffin, naphthenic, and aromatic compounds. The saturation point at 20 °C varies from approximately 30 parts per million (ppm) of paraffin oils to over 200 ppm of fully aromatic liquids,
but it is typically between 40 to 80 ppm. Solubility may increase significantly with the use of additives. Oxidation products also increase solvating efficiency. Mineral-based transformer
oils typically have very little additives and therefore have low solubility like base oil, whereas lubrication oils with greater amounts of additives generally have much higher solubility.
Vacuum Sampling Pump
Makes sampling easy. Use with the oil sampling kits. Sample bottle screws into the pump head and tubing draws the oil from the reservoir.
