Add 10 Cc. of ether to the contents of the flask, rotate it, and again decant the ethereal layer upon the inner filter.
Page 58 - ... and afterwards wash them, drop by drop, from a pipette, with alcohol previously saturated with powdered morphine. When this has passed through, displace the remaining alcohol by ether, using about 10 cc or more, if necessary. Allow the filter to dry in a moderately warm place, at a temperature not exceeding 60° C. (140° F. ) until its weight remains constant, then carefully transfer the crystals to a tared watch-glass and weigh them.
Page 758 - Shake the latter thoroughly, remove the stopper, and rinse it and the neck of the flask with a little distilled water, so that the washings may flow into the flask, then add 1 cc.
Page 56 - ... when the ether has passed through, wash the funnel and cotton with a small quantity of ether and then pour the aqueous liquid into the funnel without trying to remove the crystals. Wash the crystals in the flask and the contents of the funnel with distilled water previously saturated with morphine, until the washings are colorless. Then add a few drops of distilled water to replace the morphinated water. Incline the edge of the funnel over the mouth of the flask and by means of a glass rod carefully...
Page 890 - If a carbon-free ash can not be obtained in this manner, exhaust the charred mass with water, collect the insoluble residue on a filter, burn till the ash is white or nearly so, and then add the filtrate to the ash and evaporate to dryness.

Page 322 - Is precipitated with 40 parts of tannlc acid. The tannate Is mixed with 25 parts of powdered litharge and 50 parts of purified animal charcoal and dried. From the dried mass the digitalis bodies are extracted with 90 per cent, alcohol, the latter Is distilled off and the residue washed with distilled water and again taken up In 90 per cent, alcohol. This is again distilled and the residue exhausted with chloroform.
Page 758 - Shake the flask repeatedly during half an hour, allow it to stand for fifteen minutes, remove the stopper just sufficiently to introduce quickly 5 cc. of an aqueous solution of potassium iodide (1 in 5), being careful that no bromine vapor escapes, and at once stopper the flask. Shake...
