    Abstract: A method for transferring a filter membrane (130) bearing a retentate to a reagent pad (310), in which the membrane is mounted in a support frame (120) having a shoulder (121) and a skirt (122) projecting from the shoulder, the pad being mounted on a cassette (300) of complementary form to said skirt, the skirt being adapted to slide sealingly on the cassette until it comes into abutment formed by the shoulder, the method comprising the steps of sealingly engaging the skirt of the membrane support frame on the cassette, establishing a pressure difference between the cassette and the membrane support frame such that the membrane adopts the shape of a dome pointing towards the pad, while maintaining the pressure difference, applying a force on the frame so as to make the skirt slide on the cassette until contact is established between the end of the dome and the pad, maintaining a force on the frame so as to move it downward until it comes into abutment formed by the shoulder while maintaining the pressure difference.

    Abstract: A method of aerosol integrity testing of filters, capable of detecting single defects that are less than 20 μm in diameter, and even as small as 2 μm in diameter, in liquid sterilizing grade filters such as filter cartridges. The method challenges the filter in a dry state with a particle stream of aerosol particles of the appropriate size and in the appropriate concentration, such that at least one or more of the particles in the stream will penetrate a defective region or regions within the membrane but will not penetrate in the integral region of the membrane. Wetting of the filter is not required.

    Abstract: Sample preparation device for receiving in sealing relation one or more filter assemblies and one or more sample containers, each container uniquely positioned within the device to receive filtered sample from a designated filter. The device includes a body, a lid disposed on the body, a container tray, a base, an integrated seal on the body, a valve and a valve actuator. The tray can be disposed in a vacuum chamber defined by the lid and the body, and one or more sample containers can be disposed in the tray. When properly positioned in the tray in the vacuum chamber, each container is in fluid communication with a single respective filter assembly disposed in sealing relation in a respective aperture in the lid. A single actuation of a valve to place the vacuum chamber under vacuum causes the lid to seal to the base and drives the simultaneous filtration of a plurality of samples.

    Abstract: The embodiments disclosed herein are directed to an apparatus useful in conducting detection of compounds on blotting membranes. The device is comprised of several layers including a porous support layer below the blotting membrane(s), a flow distributor above the blotting membrane(s) and optionally a well on the flow distributor to contain the liquid to the desired area and to allow for lower starting volumes of such liquid. Preferably, the flow distributor is a non-binding or low binding hydrophilic porous membrane such as a 0.22 micron membrane and the support layer is a grid or sintered porous material. The distributor and support are held together to form an envelope around the membrane(s). The use of a hinge, clips and other such devices is preferred in doing so.
