Next, a predetermined volume is sampled from the organic solvent in which the fats and oils have been extracted and dissolved. The POV meter of this coulometric titrator is composed of a coreless motor, an agitator attached to a stirring rod connected to the motor, a shatterproof disk fixed to an upper surface thereof, and a shatterproof disk fixed to the upper part and a nitrogen inlet. According to Faraday's law, the relationship between the quantity of electricity and POV is such that the quantity of electricity corresponding to 2 ml of 0. An apparatus for filtering a pulverized sample from an organic solvent is as follows: Normal suction filtration can be applied. The specific gravity of the solvent, the specific gravity of the fat or the like, etc. Shake or agitate as necessary to facilitate extraction of fats and oils.
