1. A device for storing and dispensing reagent components in an automated clinical analyzer, comprising:
- a housing comprising a first opening and a first end adjacent to said first opening, said housing extending to a second end opposite to the first end, and internal threads extending from said first end of said housing along an internal surface of said housing to the second end of said housing, said housing defining a lumen having a long axis positioned between the housing first and the second ends;
a cylindrical member positioned within the lumen of the housing and oriented along the long axis of the housing lumen, said cylindrical member comprising a cylindrical member first end positioned in the lumen of said housing at the first end of said housing, and a cylindrical member second end positioned in the lumen of said housing opposite to said cylindrical member first end, said cylindrical member comprising external threads extending from said first end of said cylindrical member to said second end of said cylindrical member and mateable with the internal threads of said housing, said cylindrical member rotatable and translatable on said internal threads of said housing from said housing first end towards a seal, said seal positioned across the lumen of said housing at the housing second end; and
,a chamber formed in the lumen of said housing between the second end of said cylindrical member and said seal.

17. A device for storing and dispensing reagents, comprising:
-
a housing comprising a first opening and a first end adjacent to said first opening, said housing extending to a second end opposite to the first end, said housing having a central axially disposed lumen along a long axis of the housing positioned between the housing first and the second ends, and said housing defining a chamber oriented perpendicular to the long axis of said housing; and
,a plug positioned and laterally slideable in the lumen of said chamber, said plug comprising a through-hole perpendicular to the long axis of said housing, said through-hole comprising a reservoir for storing a reagent and for releasing said reagent from said reservoir when said through-hole is aligned with the lumen of said chamber. - View Dependent Claims (18, 19)
