Systems and methods for manufacturing closed microfluidic devices
A method for manufacturing a microfluidic device can include providing a base component to define a first portion of the microfluidic device. A cap component of the microfluidic device can be fabricated with a sealing lip extending a first distance from a first side of the cap component and a support portion extending a second distance, less than the first distance, from the first side of the cap component. The method can include positioning the cap component and the base component within a mold to bring the sealing lip of the cap component in contact with the base component. The base component, the support portion of the cap component, and the sealing lip of the cap component together can define a cavity. The method can include injecting a polymer material into the mold to cause the polymer material to fill the cavity.
AN APPARATUS
An apparatus suitable for handling biological material, for directly introducing or removing material to, or from, a container, comprising a body comprising at least one resealable port; a cover comprising an aperture and wherein the cover is disposed over an upper side of the body, and wherein the cover is moveable such that an aperture of the cover is configured to expose at least part of the resealable port.
FULLY AUTOMATIC INDUCTIVE SAMPLE-COLLECTING BUCKET CAPABLE OF STORING SAMPLE INFORMATION
A fully automatic inductive sample-collecting bucket capable of storing sample information includes a bucket, and a bucket cover snap-fitted to an upper end of the bucket. A bucket cover cavity is formed in the bucket cover. A locking mechanism, and a control mechanism for driving the locking mechanism to act are integrated in the bucket cover cavity. An integrated circuit (IC) card inductive control assembly is integrated in the bucket cover. The bucket is provided with a radio frequency identification (RFID) chip. The IC card inductive control assembly is configured to identify IC card unlocking information of an external grip for cover opening work and to drive the control mechanism to work to control an action of the locking mechanism. The sample-collecting bucket integrates an RFID card capable of carrying sample coding information, and can realize the automatic cover-sealing and cover-opening function under the identification and control of the controller.
Receiving Unit for Receiving a Fluid, Method and Apparatus for Producing a Receiving Unit, Method and Apparatus for Operating a Receiving Unit, and Receiving Device
A receiving unit for receiving a fluid has a receiving element with a receiving face and at least one micro-cavity that is arranged and formed in the receiving element on the receiving face in order to receive the fluid. The receiving face further has a hydrophilic surface characteristic in at least one subregion adjoining the at least one micro-cavity.
Pipette tip system
A pipette tip system for use with a plurality of pipette tips is disclosed that includes a support card and a support card lid. The support card includes an array of pipette tip receiver openings arranged in a N×M array, wherein the N is less than M. The support card further has a short-side card rail edge on an edge of the support card along the N side of the array, and a long-side card rail edge on an edge of the support card along the M side of the array. The support card lid includes a long-side lid rail edge extending from a support card first surface, which is adapted to slidably mate with the long-side card rail edge, and a short-side lid rail edge extending from a support card second surface, which is adapted to slidably mate with the short-side card rail edge.
Gene Detection Kit and Dene Detection Device
Provided are a gene detection kit and a gene detection device. The gene detection kit includes a kit body, a piston cylinder, and a piston. The kit body has an accommodating cavity and a plurality of reagent cavities. The piston cylinder is provided in the accommodating cavity, and the piston cylinder has a piston cavity. The piston is movably provided in the piston cavity along an axial direction of the piston cylinder. A first channel in communication with the piston cavity is provided on an outer circumferential surface of the piston cylinder, a plurality of second channels are provided on an inner wall of the accommodating cavity, each of the second channels is in corresponding communication with one of the reagent cavities, and the piston cylinder can move relative to the kit body, so that the plurality of second channels are alternately in communication with the first channel.
TOOL FOR SEIZING AND EJECTING CLOSURE PLUGS FOR TUBES RECEIVING SAMPLES TO BE ANALYSED, AND USE OF SUCH A TOOL
The subject of the invention relates to a tool for manipulating a plurality of plugs, taking the form of a comb (1) comprising: a body (7) provided with a row of teeth (4) having pointed distal portions (4p) spaced apart in a linear direction in order to engage with the cavities of the plugs; a system for separating the plugs from the teeth (4) that comprises a slide returned elastically and guided to slide with respect to the body (7) in a direction parallel to the direction of extension of the teeth, the slide being provided with the fingers of the comb, which are movable by sliding between the teeth (4), and a control (11a) accessible from a first portion (1a) of the comb and which, when pressed to move translationally, causes the fingers of the comb to slide in the direction of the pointed distal portions (4p) in order to eject the plugs from the teeth (4).
Sample collection system including valve and plug assemblies
A biological sample collection system can include (i) a sample collection vessel having an opening for receiving a biological sample, (ii) a selectively movable valve comprising a core and a collar disposed about the core, and (iii) a sealing cap coupled to the collar and comprising a reagent chamber for storing a measure of sample preservation reagent. The sealing cap is configured to associate—and form a fluid tight connection—with the sample collection vessel such that associating the sealing cap with the sample collection vessel causes a physical rearrangement of the core relative to the collar such that a fluid vent associated with the core is moved into fluid communication with the reagent chamber, thereby permitting sample preservation reagent to pass from the regent chamber to the sample collection vessel.
FLOW CELL COMPRISING A STORAGE ZONE AND A DUCT THAT CAN BE OPENED AT A PREDETERMINED BREAKING POINT
A flow cell having at least one storage zone connected to a duct for conducting fluid out of, into or/and through the storage zone. The duct includes a duct section which is delimited by a substrate and a film joined to the substrate and in which the duct is sealed and can be opened at a predetermined breaking point by deflecting the film. The film covers a recess in the substrate which forms the duct section. A sealing wall that seals the duct and is integrally joined to the substrate is placed in the recess. The predetermined breaking point is formed by a breakable joining region between the film and an edge portion of the sealing wall facing the film. The dimensions of a peripheral area of the sealing wall is formed in the edge portion and runs parallel to the film determine the surface area of the joining region.
SAMPLE MANIPULATION AND ASSAY WITH RAPID TEMPERATURE CHANGE
Among other things, the present invention is related to devices and methods of performing biological and chemical assays, particularly an easy sample manipulation and/or a rapid change or a rapid thermal cycling of a sample temperature is needed (e.g. Polymerase Chain Reaction (PCR) for amplifying nucleic acids).
