In such cases the diffi-cultly soluble portions may be allowed to remain undissolved, andon filtering the solution are retained by the filter. Filtration of the Solution. — When a substance has been dis-solved, the solution must next be filtered from the insoluble im-purities like by-products, filter-fibres, inorganic compounds, etc.For filtration a funnel with a very short stem is generally used,i.e. an ordinary funnel the stem of which hasbeen cut off close to the conical portion (Fig. i).The funnels used in analytical operations havethe disadvantage that when a hot solution ofa compound flows through the stem, it be-comes cooled to such an extent that crystalsfrequently separate out, thus causing an obstruc-tion of the stem. The funnel with a shortenedstem or no stem is prepared with a folded filter. In case thesolution contains a substance that easily crystallises out, the filterpracticalmethods00gatt
