1. An apparatus, comprising:
- a sample tube;
a housing having a connection portion configured to mate with the sample tube, the housing further including a side wall defining an inner reagent volume of the housing, the housing further comprising a top opening into the inner reagent volume, the housing further including a bottom end wall that separates the inner reagent volume from the sample tube when the housing is coupled to the sample tube, the bottom end wall comprising a puncturer having a sharp point, the bottom end wall further comprising a through hole that defines a delivery path between the inner reagent volume and the sample tube, the bottom end wall further including a plurality of protrusions projecting inwardly from a side surface of the through hole in the bottom end wall into the delivery path;
a blister container within the inner reagent volume, the blister container containing a reagent and including a frangible portion; and
an actuator having a plunger coupled to an engagement portion, the engagement portion accessible through the top opening, the engagement portion configured to be manipulated to move the plunger within the inner reagent volume such that the puncturer pierces the frangible portion of the blister container to convey the reagent from the inner reagent volume into the sample tube via the delivery path.

Abstract
An apparatus includes a housing and an actuator. The housing, which defines a reagent volume that can receive a reagent container, can be removably coupled to a reaction chamber. A delivery portion of the housing defines a delivery path between the reagent volume and the reaction chamber when the housing is coupled to the reaction chamber. The delivery path includes a protrusion such that the delivery path has a discontinuous inner surface. The actuator can be moved to convey a reagent from the reagent container into the reaction chamber via the delivery path.

11. An apparatus, comprising:
-
a sample tube; a housing having a connection portion configured to mate with the sample tube, the housing further including a side wall defining an inner reagent volume of the housing, the housing further comprising a top opening into the inner reagent volume, the housing further including a bottom end wall that separates the inner reagent volume from the sample tube when the housing is coupled to the sample tube, the bottom end wall comprising a puncturer having a sharp point, the bottom end wall further comprising a through hole that defines a delivery path between the inner reagent volume and the sample tube, a lower-most surface of the bottom end wall defining an exit opening of the through hole through which an exit flow of a reagent is conveyed when exiting the delivery path, the bottom end wall further including a plurality of protrusions projecting inwardly from a side surface of the through hole in the bottom end wall into the exit opening; a blister container within the inner reagent volume, the blister container containing the reagent and including a frangible portion; and an actuator having a plunger coupled to an engagement portion, the engagement portion accessible through the top opening, the engagement portion configured to be manipulated such that the puncturer pierces the frangible portion of the blister container to produce the exit flow of the reagent through the delivery path and the exit opening. - View Dependent Claims (12, 13, 14, 15, 16)
