Abstract: A component (8) adapted to engage with a receiver (6) has an array of contact pads (16) to removeably connect with a corresponding array of connectors (18) on the receiver (6). Each contact pad (16) of the array is electrically connected to the electrode (26) of a corresponding recess or well (28) that is part of a sensor, wherein a membrane is formable across each recess. A conductive grid (102) is configured between the contact pads (16) of the array, to inhibit an electrostatic discharge (ESD) conducting across the recesses or wells and/or direct an ESD away from the recesses or wells.

Abstract: A microfluidic device for analysing a test liquid comprises: a sensor (235), such as a membrane provided with nanopores, provided in a sensing chamber (237); a sensing chamber inlet channel (261) and a sensing chamber outlet channel (262), each connecting to the sensing chamber for respectively passing liquid into and out of the sensing chamber, and a reservoir (233) forming a sample input port to the microfluidic device, the reservoir being in fluid communication with the sensing chamber inlet channel (261); a liquid collection channel (232); a barrier (231) between an end of the sensing chamber outlet channel (262) and the liquid collection channel (232); a first seal (251), covering the sample input port; a second seal (252), covering the end of the sensing chamber outlet channel (262), thereby preventing liquid from flowing from the sensing chamber (237), over the barrier (231), into the liquid collection channel (232); wherein the microfluidic device is filled with a liquid from the first seal (251) at t

Abstract: A kit which has a first and second component parts, which are adapted for connection with each other. The first component part has a first array of electrical sensors, two substantially parallel lateral walls on the sides of the electrical connectors, two rails extending along the sides of the array, a front contact point and an overhang for receiving the second part. The second component part has a second array of electrical sensors for connection to the first array, front end configured to fit between the lateral walls of the first connector, and lateral sides having rail reliefs to fit the rails of the first connector. Connection of the first component part and the second component part forms a shoulder that aligns to locate the second array of electrical connectors in correct position for connection to the first array of electrical connectors.

Abstract: A kit comprising first and second component parts adapted for connection to each other, wherein: the first component part comprises: a first array of electrical connectors; two substantially parallel lateral walls, one provided on either side of the first array of electrical connectors at a predetermined position with respect to the first array of electrical connectors; two rails provided between the first array of electrical connectors and the lateral walls, one rail being on either side of the first array of electrical connectors, wherein each rails extends at least along a length of the first array of electrical connectors, and has a front tip positioned at a predetermined position with respect to the first array of electrical connectors; a front contact point; an overhang for receiving the second component; the second component part comprises: a second array of electrical connectors, for connection to the first array of electrical connectors; a front end being configured to fit to a width between the para

Abstract: A sachet (1) having walls of flexible material is disclosed. The walls are joined so as to form an impermeable seal, thereby defining a cavity within the sachet (1). A conduit (2) passing through the seal and having inner and outer ends is disposed with the inner end within the cavity and the outer end outside the sachet (1) such that the cavity is in fluid communication, via the conduit, with the outside of the sachet. The cavity contains a volume of liquid (8) in use, and the conduit (2) is adapted to prevent the liquid (8) flowing from the cavity without the application of an additional stimulus, irrespective of the orientation of the sachet (1).

Abstract: A dispenser system comprising a reservoir, a closure device for controlling the flow of liquid from the reservoir, and a housing to which the reservoir is attached is disclosed. The reservoir is movable relative to the housing from a storage position in which the closure device prevents liquid flowing from the reservoir to a dispensing position in which the closure device allows liquid to flow from the reservoir. The housing comprises an activation device which on movement of the reservoir from the storage position to the dispensing position causes the closure device to allow the liquid to flow from the reservoir.
