The container body has a first side wall and an opposing second side wall. The fluid container also includes one or more container alignment features disposed on an outer surface of the first side wall and configured to self-align the container body with a datum. The fluid container also includes one or more anti-evaporation tube alignment mechanisms disposed on one or more inner surfaces of the container body and configured to self-align an anti-evaporation tube within the container body. ## Claims ### Claim 1 A fluid container comprising: a) a wedge shaped container body comprising a rigid first side wall and an opposing second side wall, wherein the container body is configured to hold one or more fluids; b) one or more container alignment features comprising a flexible convex outer surface disposed on and extending outwardly from an outer surface of the first side wall of the container body; wherein, when the fluid container is held in a compartment of a reagent server ring comprising a first compartment wall, an opposing second compartment wall, and a protrusion from the second compartment wall, the flexible convex outer surface applies a spring force to the first compartment wall and aligns the fluid container with the protrusion from the second compartment wall; and c) one or more anti-evaporation tube alignment mechanisms comprising a concave inner surface disposed on and extending inwardly from one or more inner surfaces of the first and second side walls and configured to self-align an anti-evaporation tube within the container body along a length of the anti-evaporation tube. ### Claim 2 (depends on 1) The fluid container of claim 1, wherein the one or more container alignment features are configured to prevent the container body from moving greater than a threshold container displacement distance from an initial self-aligned container location, and the one or more anti-evaporation tube alignment mechanisms are configured to prevent an anti-evaporation tube in the container body from moving greater than a threshold tube displacement distance from an initial self-aligned anti-evaporation tube location in the container body. ### Claim 3 (depends on 1) The fluid container of claim 1, further comprising a container opening in the container body, wherein the one or more container alignment features are configured to self-align the container opening with the protrusion and prevent the container opening from moving greater than a threshold opening displacement distance from an initial self-aligned container opening location. ### Claim 4 (depends on 1) The fluid container of claim 1, wherein the one or more anti-evaporation tube alignment mechanisms comprise: a pair of opposing anti-evaporation tube alignment mechanisms disposed on opposing inner surfaces of the first and second side walls. ### Claim 5 (depends on 4) The fluid container of claim 4, wherein each opposing anti-evaporation tube alignment mechanism has concave surfaces configured to face the anti-evaporation tube in the container. ### Claim 6 (depends on 1) The fluid container of claim 1, wherein the one or more anti-evaporation tube alignment mechanisms comprise a container neck disposed at an upper portion of the container body and having an inner surface configured to receive a force from an upper portion of the anti-evaporation tube. ### Claim 7 A fluid container comprising: a wedge shaped container body configured to hold one or more fluids, the container body comprising a rigid first container side wall and an opposing second container side wall; and one or more container alignment features comprising a flexible convex outer surface disposed on and extending outward from an outer surface of the first container side wall of the container body; wherein, when the fluid container is held in a compartment of a reagent server ring comprising a first compartment wall, an opposing second compartment wall, and a protrusion from the second compartment wall, the flexible convex outer surface applies a spring force to the first compartment wall and aligns the fluid container with the protrusion from the second compartment wall. ### Claim 8 (depends on 7) The fluid container of claim 7, wherein the container body is configured to be held in a compartment of a reagent server ring having a first compartment wall and a second compartment wall. ### Claim 9 (depends on 7) The fluid container of claim 7, further comprising a container opening in the container body, wherein the one or more container alignment features are configured to self-align the container opening with the protrusion and prevent the container opening from moving greater than a threshold opening displacement distance from an initial self-aligned container opening location. ### Claim 10 (depends on 7) The fluid container of claim 7, wherein the at least one container alignment feature is molded from the first container side wall. ### Claim 11 A fluid container comprising: a wedged shaped container body configured to hold one or more fluids, the container body comprising: (i) a container front wall; (ii) a container rear wall opposite the container front wall; (iii) a rigid first container side wall extending between the container front wall and the container rear wall; and (iv) a second container side wall opposing the first container side wall and extending between the container front wall and the container rear wall; one or more container alignment features comprising a flexible convex outer surface disposed on and extending outwardly from an outer surface of the first side wall of the container body; a first anti-evaporation tube alignment mechanism comprising a concave inner surface disposed on and extending inwardly from a first inner surface of the first container side wall; and a second anti-evaporation tube alignment mechanism comprising a concave inner surface disposed on and extending inwardly from a second inner surface of the second container side wall; wherein, when the fluid container is held in a compartment of a reagent server ring comprising a first compartment wall, an opposing second compartment wall, and a protrusion from the second compartment wall, the flexible convex outer surface applies a spring force to the first compartment wall and aligns the fluid container with the protrusion from the second compartment wall; and wherein the first and second anti-evaporation tube alignment mechanisms are configured to self-align an anti-evaporation tube within the container body along a length of the anti-evaporation tube. ### Claim 12 (depends on 11) The fluid container of claim 11, wherein the first anti-evaporation tube alignment mechanism and the second anti-evaporation tube alignment mechanism are configured to prevent the anti-evaporation tube in the container body from moving greater than a threshold tube displacement distance from an initial self-aligned anti-evaporation tube location in the container body. ### Claim 13 (depends on 11) The fluid container of claim 11, wherein the first anti-evaporation tube alignment mechanism and the second anti-evaporation tube alignment mechanism each comprise a concave surface configured to face an outer convex surface of the anti-evaporation tube in the container. ### Claim 14 (depends on 11) The fluid container of claim 11, further comprising a container neck disposed at an upper portion of the container body, and wherein the first anti-evaporation tube alignment mechanism, the second anti-evaporation tube alignment mechanism, and the container neck are together configured to self-align the anti-evaporation tube within the container body. ### Claim 15 (depends on 14) The fluid container of claim 14, wherein the first anti-evaporation tube alignment mechanism opposes the second anti-evaporation tube alignment mechanism and each anti-evaporation tube alignment mechanism is located a predetermined distance from at least one of (i) the container neck and (ii) a bottom surface of the container body to self-align the anti-evaporation tube within the container body. ### Claim 16 (depends on 14) The fluid container of claim 14, wherein the first anti-evaporation tube alignment mechanism, the second anti-evaporation tube alignment mechanism, and the container neck are together configured to align the anti-evaporation tube so that the anti-evaporation tube and a probe received by the anti-evaporation tube share a same center axis. ### Claim 17 (depends on 14) The fluid container of claim 14, wherein the first anti-evaporation tube alignment mechanism, the second anti-evaporation tube alignment mechanism, and the container neck are together configured to prevent a reagent probe from contacting the anti-evaporation tube when the reagent probe is received by the anti-evaporation tube.
