Stability Measurements

Rancimat

Rancimat

The 892 Professional Rancimat determines the oxidation stability of natural fats and oils, in their pure form as well as in fat-containing foods and cosmetics, using the established Rancimat method. To this end, it accelerates the aging process of the sample by exposing it to heat and increased volumes of air, and it measures the time that passes until oxidation takes place at a high rate – the induction time or oxidation stability index (OSI).

Biodiesel Rancimat

Biodiesel Rancimat

The 893 Professional Biodiesel Rancimat determines the oxidation stability of biodiesel (fatty acid methyl esters, or FAME for short) and biodiesel blends. In the Biodiesel Rancimat, increased temperature and a continuous stream of air through the sample accelerate its aging. The time that passes until oxidation takes place at a high rate – the induction time or oxidation stability index (OSI) – is measured.

PVC Thermomat

PVC Thermomat

he 895 Professional PVC Thermomat determines the thermostability of polyvinyl chloride (PVC) and other chlorine-containing polymers by means of the dehydrochlorination test (DHC). This involves exposing the samples to elevated temperatures in the PVC Thermomat and measuring the stability time – the time until gaseous hydrogen chloride is released.
