1. A device comprising:
a housing having a first lumen that extends along a central axis of the housing and that extends to a container, the housing having a second lumen, the first lumen having a first opening and the second lumen having a second opening, the first opening being perpendicular to the second opening. the second lumen bisecting the first lumen such that the first lumen is above and below the second lumen; and
a slider comprising through-holes containing reagent components that are powder or liquid,
where the slider is arranged within the second lumen and is slidable within the second lumen to move between multiple positions including a first position,
where, in the first position, all of the through-holes containing the reagent components align to the housing and not to the first lumen so that the housing blocks the through-holes and so that the reagent components remain in the through-holes, and
where, in positions different from the first position, respective ones of the through-holes align to the first lumen to create respective flow paths for respective reagent components through the first lumen, through the respective ones of the through-holes, and into the container.
