An aseptic coupling device includes: a main body defining a front face; a membrane coupled to the front face, the membrane including a first portion coupled to the front face and a second portion folded over on the first portion; and a low friction member positioned between the first and second portions of the membrane.

Some fluid coupling devices described herein are configured for use in fluid systems for purposes of providing a single-use, disconnection functionality that can substantially limit fluid spillage when being disconnected. In some embodiments, the coupling portions cannot be functionally reconnected to each other after being disconnected from each other.

A pipe coupling member includes a coupling body defining a part of a fluid passage, and a support member disposed inside the coupling body. A valve accommodating space is defined inside the coupling body at a position forward of the support member, and a valve element is disposed in the valve accommodating space to open and close the fluid passage. The coupling body is formed from a thin-walled pipe material and has a deformed recess formed by plastically deforming radially inward a portion of the coupling body that covers an annular groove of the support member. The deformed recess has a locking element latching surface along a support surface of the annular groove. When the pipe coupling member is connected to an associated pipe coupling member, the locking element latching surface is latched by a locking element of the associated pipe coupling member.

An aseptic coupling arrangement can include a first coupling device and a second aseptic coupling device. In one embodiment, the first and second coupling devices are substantially similar, each having a main body defining a front face and a fluid passageway therethrough. A first connecting feature disposed on the main body of each coupling device may be provided for aligning and coupling the aseptic devices together. Each coupling device may also include a sealing member received in the main body and a membrane removably coupled to the main body front face to cover the sealing member. The first aseptic coupling device may also include a rotatable protective cover that is removably attached to the main body and connected to the membrane. In one embodiment, the removal of the protective covers away from two coupled main bodies, in a direction parallel to the front faces, causes removal of the membranes.

Various embodiments provide a connector for the sterile transfer of a liquid medium from a container to a bioprocess engineering system. The connector has two coupling devices. The coupling devices each have a housing and a control element which is adjustably mounted in the housing interior and forms a channel. The channel extends from a control element inlet opening to a control element outlet opening. The housings are able to be mechanically connected to one another and have a fluid inlet and a fluid outlet. The fluid outlet of one housing and the fluid inlet of the other housing overlap. The control elements are each adjustable from a starting position, into an operating position, in which the control element inlet opening is fluidically connected to the fluid inlet and the control element outlet opening is fluidically connected to the fluid outlet.

A breakaway coupling for connecting two fluid lines, comprising a first coupling part (3) which can be connected to the first fluid line and a second coupling part (4) which can be connected to the second fluid line. The coupling parts (3, 4) can be disconnected from one another by way of a defined disconnecting force, wherein at least one of the coupling parts (3, 4) has an outflow prevention valve (20) with a valve seat (21) and with a sealing body (14) which is configured for interaction with the valve seat (21). The outflow prevention valve (20) has a hold-open element (16) which is configured to enable a passage of the fluid in the joined-together state of the coupling parts (3, 4). The outflow prevention valve (20) is configured to prevent an outflow of the fluid from at least one of the fluid lines in the disconnected state of the coupling parts (3, 4). The breakaway coupling has an anti-rotation safeguard which, during operation of the coupling, prevents a rotation of the first coupling part (3) and the second coupling part (4) with respect to one another. According to the invention, the valve seat (21) has a bearing surface (24) for the sealing body (14), wherein a compensatory element (25) is arranged in the region of the bearing surface (24), which compensatory element (25) consists of a material which has a lower hardness than the material of the valve seat (21) and/or than the material of the sealing body (14).

Example implementations relate to a liquid cooling interconnect module of a computing system, and a tool-less method of assembling the liquid cooling interconnect module having a housing, a biasing member, and an interconnect block. The housing has an interlocking member, a support assembly, and a bore extending between a first end and a second end of the housing. The biasing member is disposed within the bore such that it contacts the support assembly. The interconnect block having a pair of through openings, is configured to be slidably inserted within the bore such that it contacts the biasing member. Further, the interconnect block is configured to compress the biasing member against the support assembly to a compressed position when the interconnect block is inserted into the bore, and the interlocking member is configured to retain the interconnect block within the housing when the biasing member is in the compressed position.
