The filter system having a filter and a filter holder, wherein the filter is connected to an upper and a lower filter cap, wherein on the circumference of the filter caps a cross-sectionally T-shaped fixing aid is respectively mounted, having a laterally projecting transverse web, which are vertically aligned with each other, wherein on an outer side of the housing of the filter holder two filter fixings are mounted with grooves in which the transverse webs can be suspended, is characterized in that four hydraulic ports project laterally from the filter and/or the filter caps, which are vertically aligned with each other, and that the filter holder has four connection connectors, which can be advanced by an upper and a lower closure mechanism against spring force until they engage in an end position in which the connection connectors are tightly connected to the hydraulic connections.

A thermally sterilizable fluid filter (10) for concentrating substances contained in a fluid by way of micro-, nano- or ultrafiltration of the fluid, particularly for concentrating a pharmaceutical precursor and/or intermediate, in particular a vaccine, in a fluid. The fluid filter has a filter housing with a fluid inlet, a retentate outlet and a permeate outlet. A filter cartridge is arranged in the filter housing (12) and has a filter medium of a ceramic material and/or a ceramic composite material. The filter cartridge is arranged held with axial play on the filter housing.

A membrane tube is provided for the permeative separation of a gas from gas mixtures. The membrane tube has at least two membrane tube sections, each with a porous, gas-permeable, metallic, tubular support substrate, and a membrane which is selectively permeable for the gas to be separated off. The tube also has, applied to the support substrate around the circumference, at least one connecting section which is gastight at least on the surface and by way of which the two adjacent membrane tube sections are joined, and at least one spacer in the region of the connecting section. The spacer projects in the radial direction to above the membrane.

A flat-plate filter for water treatment and a flat-plate filter module comprising the same are provided. The flat-plate filter for water treatment according to an embodiment of the present invention comprises: a piece-shaped filtration member comprising a first support and a membrane formed on both sides of the first support; and a support frame fitted in and coupled to the edge of the filtration member so as to support the filtration member, and having a flow path through which filtered water introduced from at least one surface of the filtration member flows, wherein a part of the filtration member is disposed in the flow path or at the edge of the flow path such that the first support is exposed.

The present disclosure provides apparatus and methods for processing liquids or fluids. Such apparatus and methods are convenient and efficient for low-cost separation, filtration, capture, collection, and/or storage of biologics and related materials. Provided apparatus and methods are designed for point-of-care use and offer advantages for patients and medical practitioners, including advantages in diagnosis and long-term monitoring of conditions.

A connecting system (1) has at least one connector (2) for a filter cassette (4) that can be inserted into a filter holder and has filter layers (5) between two end plates (6), and seals (7) between the filter layers (5) and/or between the end plates (6) and an adjacent filter layer (5). The connector has tensioning parts that engage in one another in a longitudinally displaceable manner and that can be fixed to the end plates (6) via their ends facing away from one another. The connector exerts a pretensioning force onto the end plates (6) when it is deflected to its maximum extent. The pretensioning force pulls the end plates (6) towards the filter layers (5), and when a contact-pressure force superimposed on the pretensioning force is applied to the end plates (6), the tensioning parts can be pushed towards one another correspondingly with the end plates (6).

Devices and methods are provided that permit efficient and selective separation of liquid biological specimens into at least two constituent components to facilitate subsequent quantitative and qualitative analysis on at least one analyte of interest in at least one of the components. The devices generally include one or more sample deposition regions supported on a base. Each sample deposition region includes a separation membrane for separating the liquid biological specimen into two different fractions. The first fraction is trapped by the separation membrane while the second fraction passes through the separation membrane and into a respective collection membrane. The separation and collection membranes are easily separable from the devices and can be utilized for further processing and analysis.

A hollow fiber membrane sheet-like object in which a plurality of hollow fiber membranes is aligned in parallel with each other and fixed to each other while both end faces of each of the hollow fiber membranes in a longitudinal direction are open, wherein at least one belt-like binding portion made of an elastic body having an elongation percentage (E) stipulated by JIS K6251 of 100% or more and extending in a direction perpendicular to the longitudinal direction is formed at each of both end portions of the hollow fiber membrane sheet-like object, and the plurality of hollow fiber membranes is fixed to each other.

A detonator positioning device for use with a wireless detonator in a perforating gun assembly includes a single mechanism for physical electrical connection, while the remaining electrical connections are made via electrically contactable components.

A ceramic membrane filtration assembly includes a housing and a membrane assembly. The membrane assembly includes at least one membrane with channels therein. A first inner end cap device is disposed within the housing and is coupled with the membrane assembly. The housing has a bypass near an outer perimeter of the first inner end cap device, the first inner end cap device has an inner port, the inner port fluidly coupled with the channels of the membrane, where the bypass includes a space between the housing and the first inner end cap device. A first outer end cap device is coupled with the first inner end cap device; the first outer end cap device has a first port and a second port, where the first port is fluidly separate from the second port, and the first port is fluidly coupled with the inner port.
