Oxidation Stability Test Apparatus for Gasoline and Aviation Fuels for Petroleum Testing Equipment

The Gasoline and Aviation Fuel Oxidation Stability Test Apparatus is designed to evaluate the tendency of gasoline and aviation fuels to form gum during storage. The sample is oxidized inside a stainless steel pressure vessel initially charged with oxygen at 100 psi (689 kPa) and heated under controlled conditions.

For gasoline, the test determines the time required for a specified pressure drop. For aviation fuels, it measures the gum and precipitate formed after a specified aging period.

The apparatus is available in water or liquid bath and solid block bath configurations. The liquid bath models feature insulated stainless steel tanks, support racks, port covers, and temperature control systems. The solid block models use insulated aluminum blocks with microprocessor-based temperature control, overtemperature protection, and dual LED displays for actual and setpoint temperatures.

Manufactured by Atico Export for reliable oxidation stability testing and quality assessment of gasoline and aviation fuels.
