Abstract

For use with an apparatus for performing biological fluid assays, the apparatus having a probe assembly that includes a tubular probe, a probe wash station for washing the tubular probe with a washing fluid. The probe wash station comprises a probe washing receptacle that is adapted to receive the tubular probe, the receptable having an anti-splash mechanism therein for preventing the splashing of the washing fluid.

Claims

1. For use with an apparatus for performing fluid analyses, said apparatus having a probe assembly that includes a primary probe and at least one auxiliary probe juxtaposed to said primary probe, a probe washing station for washing said primary probe and said auxiliary probe with a washing fluid, comprising

a washing reservoir that comprises a frustoconical top portion and a cylindrical lower portion, said cylindrical lower portion being adapted to receive said primary probe and to retain a volume of washing fluid in which to partially immerse the primary probe;

and

a washing platform that is adapted to assist in the washing of said auxiliary probe, wherein

the cylindrical lower portion of the reservoir includes a conical member positioned at the base of said lower portion with its apex proximate to said primary probe in order to prevent splashing of said washing fluid that is exiting said primary probe.

2. The probe wash station as claimed in claim 1, wherein said conical member maintains its anti-splashing characteristic even when said primary probe is misaligned with the axis of said conical member.

3. The probe wash station as claimed in claim 2, wherein the circulation of said washing fluid in said cylindrical lower portion washes the exterior of said primary probe.

4. The probe wash station as claimed in claim 3, wherein the flow of said washing fluid over said washing platform performs said washing of said auxiliary probe.

5. The probe wash station as claimed in claim 4, further comprising

an outlet for permitting the exit of said washing fluid from said probe wash station.

6. For use with an apparatus for performing fluid analyses, said analytical apparatus having a probe assembly that includes a probe,

a probe wash station for washing said probe with a washing fluid comprising:

a probe washing receptacle that is adapted to receive said probe and to retain a sufficient volume of washing fluid in which to partially immerse the probe; and

an anti-splash mechanism contained within said probe washing receptacle for preventing the splashing of wash fluid which is dispensed from said first probe, said anti-splash mechanism being a conical member positioned at the base of said receptacle with the apex of said conical member proximate to said probe.

7. For use with an apparatus for performing fluid analyses, said analytical apparatus having a probe assembly that includes a first probe and at least one auxiliary probe that is juxtaposed to said first probe,

a probe wash station for washing said probes with a washing fluid comprising:

a probe washing receptacle that is adapted to receive said probes and to retain a sufficient volume of washng fluid to partially immerse at least the first probe; and

an anti-splash mechanism contained within said probe washing receptacle for preventing the splashing of wash fluid which is dispensed from said first probe, said anti-splash mechanism being a conical member positioned at the base of said receptacle with the apex of said conical member proximate to said first probe.
