Liquid Bath is an instrument commonly used in petroleum industry to determine the tendency of aviation fuels and gasoline to form gum in storage conditions. It is also used to measure the oxidation stability of fuels.

Salient Features

• The instrument is provided with constant temperature baths for heating oxidation pressure vessels.
• The instrument conforms to the specifications of American Standard of Testing Materials (ASTM).
• There are two types of models available for the instrument.
• There is a two-unit water analog-controlled water bath that can be installed on a table top if required.
• The instrument is equipped with an overflow standpipe or drain to maintain the proper depth when the pressure vessels are introduced.
• Provided with a brass plated reflux condenser to minimize evaporation loss.
• The equipment is supplied with a low liquid level controller.
• The instrument has double-wall insulated construction with support racks, stainless steel tanks, and port covers.

Test Method

• The sample to be tested is oxidized inside a stainless steel pressure vessel, which is charged with oxygen at 100psi and heated in a boiling water bath.
• The amount of time required for a specified drop in pressure of gasoline or the quantity of gum and precipitate formed after a specific aging period of aviation fuels is determined.

Applications

There are various applications of liquid bath. Some of it's common applications are in:

• Petroleum Industry
• Aeronoautics
• Mineral Oil Industry
• Fuels
