# Council Decision of 14 November 1992 laying down methods for the analysis and testing of heat-treated milk for direct human consumption (92/608/EEC), Division 6.5.6: Carefully remove the cork or stopper and rinse it and the inside of the neck of the flask with a little of the mixed solvent (4.6.) so that the rinsings run into the flask.

Extent: E+W+S+N.I.

If the interface is below the bottom of the neck of the flask, raise it slightly above this level by gently adding water down the side of the flask to facilitate decantation of solvent.
