Product Details The Micro-Separometer is an electro-mechanical instrument used to rate water separation characteristics. The Micro-separometer employs the use of a turbidimeter, a mechanical mixer, and a disposable filter. A portion of the sample, in a clear glass vial, is used to set the meter to read 100. The sample in the vial is discarded and the vial is retained. Another portion of the sample in a plastic syringe is used to create a water/fuel emulsion using the mixer. The emulsion is passed through the filter at a programmed rate and a portion is collected in the retained vial. The vial is replaced in the turbidimeter and the water separation characteristic of the fuel is rated.
