KN-7345 Automatic Micro Distillation Apparatus
KN-7345 Automatic Micro Distillation Apparatus conforms to ASTM D7345 Standard Test Method for Distillation of Petroleum Products at Atmospheric Pressure (Micro Distillation Method). The distillation (volatility) characteristics of hydrocarbons have an important effect on their safety and performance, especially in the case of fuels and solvents. The boiling range gives information on the composition, the properties, and the behavior of the fuel during storage and use. Volatility is the major deRead

KN-1160 Vacuum Distillation Apparatus
The sample is distilled at an accurately controlled pressure between 0.13 and 6.7 kPa (1 and 50 mm Hg) under conditions that are designed to provide approximately one theoretical plate fractionation. Data are obtained from which the initial boiling point, the final boiling point, and a distillation curve relating volume percent distilled and atmospheric equivalent boiling point temperature can be prepared.Read

KN-4006A Water in Crude Oil Apparatus (Distillation Method)
The sample is heated under reflux conditions with a water immiscible solvent which co-distills with the water in the sample. Condensed solvent and water are continuously separated in a trap—the water settles in the graduated section of the trap, and the solvent returns to the distillation flaskRead

KN-6304V Vaporizer
Disposable vials can be used to take samples for heating vaporization, which is for standard weight solid or quasi-solid samples, such as: plastic particles, toner, inorganic salts, battery separators, liquid crystals, coatings, food, pharmaceuticals, etc.
Working principle: The water in the sample is vaporized through the heater, and the water is carried into the reaction bottle by high-purity nitrogen as the carrier gas to participate in the Karl Fischer reaction, so as to obtain the water coRead

KN-203 Volumetric Karl Fischer Moisture Titrator
although the volumetric KF titration can determine low levels of water,it is generally accepted that coumometric KF titrations are more accurate for routine determination of very low levels of water. as a general rule, if samples routinely contain water concentrations of 500Mg/kg or less,the coumometric tech should be considered.Read

KN-titrate Automated Potentiometric Titrator
New and used petroleum products, biodiesel and blends of biodiesel may contain acidic constituents that are present as additives or as degradation products formed during service, such as oxidation products. The relative amount of these materials can be determined by titrating with bases. The acid
number is a measure of this amount of acidic substance in the oil, always under the conditions of the test. The acid number is used as a guide in the quality control of lubricating oil formulations. ItRead
