The sample is evaporated and condensed under controlled conditions, and observations are made of the temperatures at which various percentages are recovered and/or the percentages recovered at specific temperatures.

The Automated Tag Closed Cup flash point tester ensures the accuracy and precision required according to the ASTM D56 and related test methods. The test sample is heated at a prescribed rate of temperature increase throughout the standard temperature test range to 100°C. The flash point tests are simply conducted by mounting the flash cup filled with sample into the test position and selecting a pre-programmed test method or the search mode to determine an approximate flash point. The automation routines provide accurate test results. Ignition by gas flame or electrical ignitor is included, along with safety cut-off devices. The measurement range can be extended to –30°C by any appropriate external chiller. Supervision software is included.

This simple-to-use biodiesel GC system is ideal for the quantitative determination of free and total glycerin in B100 methyl esters by gas chromatography. The calibrated results are displayed directly, eliminating off-line calculations.

The Tackiness Tester, K95200, has been designed to provide an objective and qualitative test for tackiness. The tester quantifies the cohesive and adhesive tactile properties of greases by measuring the sample in Newton’s and replaces the old finger sticky test method with a numerical and graphical result.

Test the range of boiling points for petroleum and biofuel products with this vacuum distillation system. The sample is distilled at a reduced pressure and the initial and final boiling points are measured. A distillation curve can be generated relating volume percent distilled and the atmospheric equivalent boiling point temperature.

Penetration tests are performed on petroleum products to determine consistency and shear stability (lubricating greases) for design, quality control and identification purposes. A standard cone or needle is released from a penetrometer and allowed to drop freely into the sample for 5 seconds (or a different specified interval) at constant temperature. The depth of penetration of the cone or needle into the sample is measured in tenths of a millimeter by the penetrometer.

Evaluates oxidation stability by subjecting the sample to a temperature of 95°C in the presence of oxygen or dry air. For inhibited mineral oils, the sample is reacted with oxygen in the presence of water and an iron-copper catalyst.

Salt content is determined by measuring the conductivity of a solution of crude oil in a polar solvent when subjected to an alternating electrical current and is obtained by comparison of the resulting conductance to a calibration curve of known salt mixtures.
