Abstract:
A microchip includes a vessel portion, an elastic member, and a flow channel which leads a liquid sample to the vessel portion. After a liquid sample is put in the vessel portion, the liquid sample is heated while pressure is applied with respect to an inner portion of the vessel portion.
Abstract:
A channel control mechanism for a microchip has a laminated structure formed of members including elastic members, and includes: a sample reservoir for packing a sample therein; a reaction reservoir in which mixture and reaction of the sample are performed; and a channel formed in a middle layer of the laminated structure, for bringing the sample reservoir and the reaction reservoir into communication with each other. The channel control mechanism performs the reaction and analysis in such a manner that the sample is delivered into the reaction reservoir through the channel. A shutter channel (pressurizing channel) is provided in a layer different from a layer in which the channel is formed so that the pressurizing channel partially overlaps the channel. The channel is closed through applying a pressurized medium to the shutter channel (pressurizing channel), and the channel is opened through releasing a pressure of the pressurized medium.
Abstract:
Provided is a sample packing device for packing a sample with respect to a microchip for performing reaction of a micro component contained in the sample, the microchip at least including: a sample reservoir; a reaction reservoir; and a channel connected between the sample reservoir and the reaction reservoir, in which a package including a sample chamber packed in advance with the sample is mounted on the microchip so as to pack the sample in the sample chamber into the sample reservoir.

Abstract:
For heating or cooling a sample contained in a vessel portion through a heat transfer member held in contact with the vessel portion, there is used the vessel portion, which has a part formed of an elastic member, expands and contracts for injection and discharge of the sample, is closed other than a connecting port with a channel connected to the vessel, and expands and contracts for injection and discharge of the sample. The vessel portion expands correspondingly to the injection when the sample is injected through an inflow path serving as the channel into the vessel portion contracting in a non-contacting state with the heat transfer member. A predetermined amount of sample is injected into the vessel portion so as to expand the vessel portion, and the vessel portion comes into contact with the heat transfer member. The vessel portion is heated or cooled through the heat transfer member.
Abstract:
A particular component in a sample is recovered in a high concentration and solvent-replaced. A separator 100 is placed on a microchip and includes a channel 112 for flowing the particular component. The channel 112 includes a sample feeding channel 300 as well as a filtrate discharge channel 302 and a sample recovering part 308 which are branched from the sample feeding channel 300. There is formed a filter 304 for preventing passage of the particular component, at the inlet of the filtrate discharge channel 302 from the sample feeding channel 300. Furthermore, there is formed a damming area (hydrophobic area) 306 for preventing entering of a liquid sample while allowing for passage of the liquid sample by applying an external force equal to or larger than a given level, at the inlet of the sample recovering part 308 from the sample feeding channel 300.
Abstract:
A sample reservoir (205) in which a sample (213) is introduced is sealed by a septum (207). On piercing the septum (207) by an injection needle, the sample reservoir (205) is communicated with the outer atmosphere, and then the sample (213) is delivered from the channel 203 to the water absorbing portion (209).
Abstract:
A test reagent container including a discharge port, formed by depressing a projecting part formed on a container bottom part, through which content can be easily and reliably discharged. The test reagent container includes: a bottom part; a peripheral wall raised approximately perpendicularly from a periphery of the bottom part; and a storage part defined by the bottom part and peripheral wall. A projecting part is formed on the bottom part in a projecting manner toward outside the container. A proximal end of the projecting part is formed in a bendable manner relative to the bottom part, and an easily breakable part is formed on a periphery of the projecting part except for the proximal end of the projecting part. The easily breakable part is broken when the projecting part is depressed from outside the container to be pushed into the inside of the container to form a discharge port.
Abstract:
Provided is an immobilization device for fitting a connecting member of a chip and a connecting member of a cover together, where a spatial clearance between the chip and cover is small. The immobilization device includes a substrate (102), a cover means (101) including a fitting means to fit with a chip (103) placed on the substrate (102), a rotating arm means (201) rotatably joined to a first joining means (301) of the substrate (102) and to a second joining means (302) of the cover means (101), and a parallel maintaining means (203) for fitting the fitting means and the chip (103) together with the fitting means and the chip (103) maintained in substantially parallel by the first joining means (301) or the second joining means (302) moving along a chip surface or a plane parallel to the chip surface. The fitting means rotates freely against the chip (103).
Abstract:
It is intended to provide a method for immobilizing, onto a column carrier, a compound having a sulfo group or a compound to which a sulfo group can be added. The method comprises immobilizing the compound onto the column carrier using a linker comprising: a sulfo group-binding group capable of forming a bond with the sulfo group in the compound; and a carrier-binding group capable of forming a bond with a group present on the surface of the column carrier.
