It is obvious that this kind of filters will suit also for pharmaceuti-cal work in all cases, which allow or require the use of a plain , furthermore, may be taken into consideration, that, no doubt, fil-tration will go on much quicker by means of such a filter than by anordinary plain filter, it offering a simple layer only of paper to theliquid to be filtered.
