Abstract:
This disclosure provides, among other things, a cartridge comprising: (a) a cartridge body comprising a malleable material and having, disposed on a surface of the body, at least one valve body comprising a valve inlet and a valve outlet, each fluidically connected to a fluidic channel; and (b) a layer comprising a deformable material bonded to a surface of the cartridge body and sealing the at least one valve body at points of attachment, thereby forming at least one valve; wherein the at least one valve body is depressed in the cartridge body relative to the points of attachment and wherein the deformable material covering the at least one valve body retains sufficient elasticity after deformation such that in a ground state the valve is open. Also disclosed is an instrument comprising a cartridge interface and a cartridge as described herein engaged with the cartridge interface, wherein (II) the cartridge interface comprises: (A) at least one mechanical actuator, each mechanical actuator positioned to actuate a valve; and (B) at least one motor operatively coupled to actuate a mechanical actuator toward or away from a valve.
Abstract:
An electrophoresis cartridge can include an integrated electrophoresis assembly including an anode sub-assembly comprising an anode, a cathode sub-assembly comprising a cathode; and at least one electrophoresis capillary having a first end in fluid communication with the cathode sub-assembly and a second end in fluid communication with the anode sub-assembly. The cartridge can further include a reagent container comprising electrophoresis buffer; a fluid conduit in fluidic communication with the reagent container; a pump in fluidic communication with the fluid conduit, the pump configured to transfer the electrophoresis buffer through the fluid conduit from the reagent container to the passage of the cathode sub-assembly; and a sample inlet port and at least one sample line, wherein the sample line places the sample inlet port in fluidic communication with the first end of the electrophoresis capillary through a passage in the cathode sub-assembly.
Abstract:
A method of controlling fluid flow in a fluid channel of fluidic cartridge can include closing a valve by actuating a mechanical actuator against the valve to force a deformable layer against walls of a valve body, wherein the valve body comprises a valve inlet and a valve outlet and each of the valve inlet and valve outlet are fluidically coupled to a fluidic channel; releasing the valve by retracting the mechanical actuator away from the valve body; and moving liquid through the valve by applying positive or negative pressure to the fluidic channel.
Abstract:
A method of making an article bonding a layer of deformable material to a surface of a cartridge body having at least one valve body thereon to seal the at least one valve body, the valve body comprising a valve floor and valve walls comprising upper parts, wherein the valve floor is recessed from the surface and the valve walls extend from the surface to the valve floor, and wherein the valve body comprises walls that are curved or sloped in a direction that is non-normal to the plane defined by the surface; and deforming the layer such that upon release of a force causing the deformation, the layer is in contact with the upper parts of the valve walls and is in spaced from the valve floor so as to bias the valve to an open state.
