Abstract: The invention relates to the filtering of liquid samples, preferably in a laboratory environment, for example for collecting micro organisms from the liquid sample for subsequent testing. The invention provides a method for filtering a liquid sample which comprises providing a blank of a deformable sheet material and a filtration medium, deforming the blank to form a funnel extending above and about the filtration medium, introducing the liquid sample to be filtered into the so formed funnel, and filtering the liquid sample from the funnel through the filtration medium, for example to a downstream receptacle. The method is accordingly based on the concept that the funnel is not or at least not completely preformed but provided in a form of a blank of a deformable material sheet which is deformed so as to form the funnel at the point and time of use during filtration.

Abstract translation: 本发明涉及液体样品的过滤，优选在实验室环境中，例如用于从液体样品中收集微生物用于随后的测试。 本发明提供了一种用于过滤液体样品的方法，该方法包括提供可变形片材料和过滤介质的坯件，使坯料变形以形成在过滤介质上方和周围延伸的漏斗，将待过滤的液体样品引入 并且将来自漏斗的液体样品通过过滤介质过滤，例如到下游容器。 因此，该方法基于以下概念：漏斗不是或至少不完全预成型，而是以可变形材料片的坯料的形式提供，该可变形材料片在过滤期间在使用的时间点变形以形成漏斗 。
