The Perfect Response for Accelerated Oxidative Stability Testing

The Velp Scientifica (Italy) OXITEST is the perfect response for accelerated oxidative stability testing, both on raw materials and finished products.

The determination of the oxidative stability is performed directly on the whole sample be it solid, liquid or doughy, with no need for preliminary fat separation, ensuring representative results.

The sample is weighed in the titanium sample holder, placed into one of the two independent titanium chambers and submitted to oxygen over-pressure of pure oxygen and high constant temperature. These two conditions drastically reduce the analysis time.

The OXITEST measures the absolute pressure change inside two independent, closed and thermostatted chambers, monitoring the oxygen uptake by reactive components present in the sample.

Results are expressed through an oxidation curve, characterised by an induction period (IP), that is the time required to reach the starting point of oxidation, corresponding to either a level of detectable rancidity or a sudden change in the rate of oxidation.

The longer the induction period, the higher the stability against oxidation over time.

The OXITEST can be used on various sample types, being the optimal solution especially designed for R&D, Product Development and Quality Control labs in food, cosmetic and petrochemical industries.
