Claims (9)
1. A reagent tube and stopper assembly comprising in combination a receptacle for containing a reagent solution and a flexible stopper for closure thereof and dispensing a spherical member into said reagent solution, said receptacle having a mouth and an elongated cylindrical wall, said flexible stopper having upper and lower surfaces, a generally cylindrical outer surface and upper and lower cavities, said lower cavity being generally spherical and having a downwardly disposed opening at said lower surface with a width less than the diameter of said spherical cavity, said upper cavity having an upwardly disposed opening at said upper surface and being separated from said lower cavity by a thin, flexible membrane, said outer surface being adapted for snug positioning within the inner cylindrical surface of the upper portion of said receptacle, said spherical cavity being adapted for holding a sphere having a diameter slightly less than the diameter of said receptacle.
2. The reagent tube and stopper assembly of Claim 1 in which a magnetic sphere is retained within said lower spherical cavity.
3. The reagent tube and stopper assembly of Claim 1 in which the diameter of the upper portion of said receptacle is greater than the diameter of the lower portion of said receptacle.
4. The reagent tube and stopper assembly of Claim 1 in which said recep- tacle is provided with an outer circumferentially disposed retaining collar at the upper portion. V
5. The reagent tube and stopper assembly of Claim 1 in which the diameter of the upper portion of said receptacle is greater than the diameter of the lower portion of said receptacle and in which said receptacle is provided with an outer circumferentially disposed retaining collar at said upper portion.
6. The reagent tube and stopper assembly of Claim 5 in which a magnetic sphere is retained within said lower spherical cavity.
7. A flexible stopper having upper and lower surfaces, a generally cylindrical outer surface and upper and lower cavities, said lower cavity being generally spherical and having a downwardly disposed opening at said lower surface with a width less than the diameter of said spherical cavity, said upper cavity having an upwardly disposed opening at said upper surface and being separated from said lower cavity by a thin, flexible membrane.
8. The flexible stopper of Claim 7 in which a magnetic sphere is retained within said lower spherical cavity.
9. A method of initiating a magnetically sensed clot timing test reaction comprising placing a magnetic sphere in the lower cavity of the stopper of Claim 7 , closing a cylindrical receptacle with said stopper, depressing a probe in the upper cavity of said stopper and against said membrane whereby said sphere is pushed out of said lower cavity and into the lower portion of said receptacle.
