Reagent supplying device
Provided are a reagent supply method and device capable of using up a reagent in a container without a remnant to the extent possible, and supplying the reagent to an analysis device without mixing air bubbles even when the remaining amount of the reagent is extremely small. The reagent supply device includes: at least one reagent container including: a container body for storing a liquid reagent; and a reagent supply port arranged on the container body; and a support member for supporting the at least one reagent container so that the reagent supply port is positioned on a lower side of the container body. The reagent supply port is sealed by a plug including at least one nozzle penetration portion. The at least one nozzle penetration portion is formed of a material having a Shore hardness of from A5° to A90°.
1. A system, comprising:
a reagent container comprising:
a container body suitable for storing a liquid reagent, and
a reagent supply port arranged on the container body; and
a support member suitable for supporting the reagent container from below, so that the reagent supply port is positioned on a lower side of the container body,
wherein the reagent supply port comprises a nozzle penetration portion, and
wherein the nozzle penetration portion comprises a material having a Shore hardness of from A5° to A90°.
2. The system according to claim 1 , further comprising a liquid feeder suitable for feeding the liquid reagent to a sample analysis unit.
3. The system according to claim 2 , wherein the reagent container is arranged at a position higher than the sample analysis unit.
4. The system according to claim 1 , wherein the support member comprises a nozzle, and the nozzle is arranged at a position corresponding to the nozzle penetration portion of the reagent container.
5. The system according to claim 1 , wherein, when the reagent container is supported by the support member, the nozzle is inserted into the nozzle penetration portion of the reagent container.
6. The system according to claim 1 , wherein the material having a Shore hardness of from A5° to A90° comprises an olefin-based elastomer or a styrene-based elastomer.
7. The system according to claim 1 ,
wherein the reagent supply port comprises a plug body and the nozzle penetration portion, and
wherein the plug body and the nozzle penetration portion are joined to each other at flanges thereof.
8. The system according to claim 1 , further comprising a housing suitable for accommodating the reagent container in a uniformly-spaced arrangement.
9. The system according to claim 1 , further comprising a housing suitable for accommodating the reagent container in a non-uniformly-spaced arrangement.
10. The system according to claim 8 , wherein the support member supports the reagent container by supporting the housing.
11. The system according to claim 1 , wherein the liquid reagent comprises a reagent suitable for liquid chromatography.
12. A sample analysis device, comprising:
the system of claim 1 ; and
a sample analysis unit.
13. The system according to claim 1 , further comprising:
an outlet portion fixed to the container body and having a screw thread,
wherein the reagent supply port is threadedly engagable with the outlet portion.
14. A reagent container comprising:
a container body suitable for storing a liquid reagent;
an outlet portion fixed to the container body and having a screw thread; and
a reagent supply port arranged on the container body,
wherein the reagent supply port comprises a nozzle penetration portion,
wherein the nozzle penetration portion comprises a material having a Shore hardness of from A5° to A90°, and
wherein the reagent supply port is threadedly engagable with the outlet portion.
15. A reagent container comprising:
a container body suitable for storing a liquid reagent;
an outlet portion fixed to the container body and having a screw thread; and
a reagent supply port removably attached to the container body via the outlet portion,
wherein the reagent supply port comprises a nozzle penetration portion and a complimentary screw thread to the outlet portion, and
wherein the nozzle penetration portion comprises a material having a Shore hardness of from A5° to A90°.
