    摘要： Filtration head (1) for a filter system, comprising base (2) including filter support (3) for removable filter element (4) and a fluid path from one side of filter element (4) on filter support (3), through filter element (4), and to drainage outlet (5) of base (2), and holder device (6) for removably attaching funnel (7) to base (2) to form a sample fluid reservoir on one side of filter element (4), wherein holder device (6) comprises ring-shaped element (8) configured to extend about bottom peripheral flange (7a) surrounding a lower end of funnel (7) and to selectively apply a biasing force on a radially outward protruding portion (7b) of bottom peripheral flange (7a) of funnel (7) to press funnel (7) against base (2). The filtration head allows the use of cardboard funnels without risk of liquid leakage between the funnel and the base.

    摘要： A pair of pliers for separating osmosis membranes. The pliers include a first arm and a second arm each having a handle end opposite a front end. A first plate includes a top surface, a bottom surface and an edge having a front, a rear and sides. The rear of the first plate is coupled to the front end of the first arm and the front of the first plate includes a taper formed on the top surface. A second plate includes a top surface, a bottom surface and an edge having a front, a rear and sides. The rear of the second plate is coupled to the front end of the second arm and the front of the second plate includes a taper formed on the bottom surface. A pivot pin pivotally secures the first arm to the second arm in between the front ends and the handle ends.

    摘要： A reverse osmosis filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a floating key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter base may be situated inline, and in fluid communication, with the raw water ingress, permeate egress, and reject water egress. The reverse osmosis filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

    摘要： The invention relates to a filtration unit, comprising a membrane filter that can be disposed on a filter support of a bottom part and an attachment that can be placed on the bottom part, wherein the membrane filter has a reinforcing edge, and wherein the membrane filter can be clamped to a clamping part of a cover of a culture medium unit for removal purposes and introduced into the culture media unit. The invention further relates to a method for the microbiological analysis of liquid samples following a filtration process, wherein after removing an attachment a membrane filter is lifted off a filter support for pouring in the liquid sample and set down on a surface of a culture medium disposed in the bottom part of a culture medium unit, and the bottom part is covered by a cover. The cover is placed on the membrane resting on the filter support such that a clamping part present on the filter support clamps to a reinforcing edge of the membrane. The cover is lifted off the filter support together with the membrane and placed on the bowl-shaped bottom part such that the bottom of the membrane facing away from the cover rests on the top of the nutrient medium facing the cover.
