*From September 15 th. 2006, UNITAN has began products quality control analysis with the FILTER METHOD. This method uses the passage of the tannin solution through pre-chromed hide powder improving sistematic results of tannins determinations. The higher sensitivity of this method enables a better measurement of tannins with results up to 5 % plus than the tannins measured with the Shake Method.
