Solid reagent containment unit, in particular for a portable microfluidic device for sample preparation and molecule analysis
A solid reagent containment unit is formed by a support; a frame body fixed to the support and delimiting internally, together with the support, an analysis volume; a reagent-adhesion structure within the analysis volume; and at least one reagent cavity, which extends within the reagent-adhesion structure. The reagent-adhesion structure is of an adhesion material embossable at temperatures lower by 6-8° C. than its own melting point and has a melting point such as not to interfere with the analysis. The reagent cavity forms a retention wall, laterally surrounding the reagent cavity, and houses dried reagents. The adhesion material is chosen among wax, such as paraffin, a polymer, such as polycaprolactone, a solid fat, such as cocoa butter, and a gel, such as hydrogel or organogel.
Device for Sealed Transfer Between Two Enclosed Volumes, Featuring Secure Opening
The invention relates to a sealed transfer device between two enclosed volumes, comprising two flanges (10, 20) that can be secured to each other by a first bayonet connection, two doors (11, 21) which close off the passage openings defined by the flanges and can be secured to each other by a second bayonet connection, and a control mechanism comprising a control member (3) that is movably mounted on the first flange (10) between a closed position and an open position of the doors (11, 21), characterized in that the control mechanism comprises a member (7) for locking the second door (21) to the first door (11), ensuring that the doors are locked together when the control member (3) switches into the open position of the first and second doors, said locking member (7) being integrated into the first door (11).
SYSTEMS AND METHODS FOR AN INTEGRATED CONSUMABLE FOR ANALYTE TESTING, INCLUDING A PREMIX APPARATUS
A system for processing a sample includes a unitary body. The unitary body including a snap lid, the snap lid having a capillary. The unitary body including a lysing container. The unitary body including a test element and a sliding actuator.
Sealed Container Comprising a Device Allowing Removable Connection to an Enclosure
The invention relates to a sealed container (1) comprising a container body (2) having a through-hole (8) that is delimited by a flange and is closed by a removable door (7) mounted on the flange, an annular seal (13) located between the flange and the door (7), the flange, the door (7) and the seal forming a sealed connection device that can be connected to a complementary connection device on a sterile enclosure by means of bayonet connection means in order to allow sterile communication between the sealed container and the sterile enclosure, characterized in that the seal (13) comprises, on its inner peripheral circumference, an annular attachment bead (130) for attaching the door (7) to the flange inserted into a notch (70) on the door (7).
MOBILE PHASE SUPPLY DEVICE WITH FLUIDICALLY NORMALLY CLOSED PORT AND CAP DEVICES
A mobile phase supply device, for supplying a mobile phase for a sample separation apparatus for separating a fluidic sample, includes a fluidically normally closed cap device configured to be mounted on a mobile phase container containing a mobile phase, and a fluidically normally closed port device configured for being mechanically connected with the cap device in such a way that, upon establishing a mechanical connection between the port device and the cap device, both the port device and the cap device are converted into a fluidically opened configuration.
Cartridge and Testing Device
The present invention relates to the field of biomedical technology and discloses a cartridge and a testing device. The cartridge comprises a sample lysis compartment, a first sample mixing compartment and a first PCR compartment; a first valve is disposed between the sample lysis compartment and the first sample mixing compartment, the first valve controls the flowing or blocking of the sample between the sample lysis compartment and the first sample mixing compartment; a fourth valve is disposed between the first PCR compartment and the first sample mixing compartment, the fourth valve controls the flow or blocking of the sample between the first sample mixing compartment and the first PCR compartment; a first reagent is provided in the first sample mixing compartment. In the compartment, nucleic acids in the sample mix with the first reagent and is then sent to the first PCR compartment for amplification.
CARTRIDGE SEALING MECHANISM
The present disclosure relates to a mechanism for fluidic sealing of a reaction cartridge in a reaction system using a single linear actuator. A single motion provided by the linear actuator is used to establish leak-resistant fluid communication between the reaction cartridge and two independent fluidic channels. The dual-sealing assembly described herein enables the use of fewer parts and a simpler control unit. The use of fewer parts and simpler control system allow for a very compact sealing mechanism and could also increase reliability, will be easier to manufacture as it will require less manufacturing testing and calibration, and is more tolerant of variance in the part being sealed (the reaction cartridge). In some embodiments, the reaction cartridge comprises a solid support matrix and a reaction reagent attached to the solid support matrix, and the reaction system is used for treating macromolecules, such as polypeptides, for sequencing and/or analysis.
Passive fluidic connection between two hydrophilic substrates
A capillary driven microfluidic system and a biosensing device including the capillary driven microfluidic system are provided. The capillary driven microfluidic system includes: a first substrate comprising at least one microfluidic channel ending in an opening, and having, adjacent to the opening, a protruding element; and a second substrate comprising at least one open cavity. The at least one protruding element and the at least one cavity include at least one hydrophilic surface. In addition, the at least one protruding element and the at least one cavity may be adapted for engaging with one another for providing transfer of a fluid between the first substrate and the second substrate. A space between the at least one hydrophilic surface of the at least one protruding element and the at least one hydrophilic surface of the at least one cavity is provided, where the separation between said surfaces is such that capillary forces are generated on the fluid upon entering inside the space.
Assessment of micro-organism presence
The present disclosure relates to a consumable sample partition device and it assembly and use. The sample partition device can be used to test a sample for absence of microorganisms (sterility) and/or for concentration of said organisms (bio-burden). The sample partition device partitions the sample input volume into multiple discrete measurement zones with little or no loss of sample (e.g., zero-loss) and with little operator involvement, thereby reducing operator- and environment-based false positives.
Connector
There is provided a connector, for introducing or extracting a material to or from at least one receptacle, comprising a housing extending between a distal end and a proximal end, the housing comprising, at least at one end, a pierceable seal; a hollow needle mounted, at least partially, within the housing between the distal end and the proximal end of the housing, a first end of the hollow needle being connected or connectable to a first corresponding receptacle, and a second end of the hollow needle facing the pierceable seal at an end of the housing; and an actuating mechanism acting on the housing or the hollow needle to enable the hollow needle to pierce the pierceable seal thereby forming a communication through the pierceable seal, such that material is able to transfer through the connector.
