A wash station for use in a clinical analyzer in an in vitro diagnostics environment for cleaning a probe, the wash station comprising: a wash nozzle comprising a vertically-elongate cavity with opposing side slits on opposing side portions of the vertically-elongate cavity shaped to allow the probe to horizontally pass through, wherein the wash nozzle is positioned within the basin such that the side slits are centered on the path of the probe ; a basin comprising an elongate body with an opened first end sized to receive and secure the wash nozzle therein; wherein the vertically-elongate cavity is configured to fill with fluid to clean the probe, a geometry of the vertically-elongate cavity allowing the wash nozzle to fill to a predetermined level while waste fluid flows out through the opposing side slits ; and wherein the basin is configured to capture the waste fluid dispensed by the probe and the wash nozzle , wherein the geometry of the vertically-elongate cavity comprises a bottom portion and a top portion , the top portion vertically expanding from a tapered region to a flared region with a top opening at a top end, the bottom portion vertically tapering to a bottom end comprising a bottom opening , wherein the waste fluid further flows out through the bottom opening, and wherein the wash nozzle further comprises a fluid inlet port connected to the vertically-elongate cavity , the fluid inlet port configured to fill the vertically-elongate cavity with the fluid to clean the probe , wherein the fluid inlet port is connected to a first side portion of the vertically-elongate cavity and is located at a point below a nominal level of the probe when inserted through one of the side slits into the vertically-elongate cavity for cleaning. a wash nozzle comprising a vertically-elongate cavity with opposing side slits on opposing side portions of the vertically-elongate cavity shaped to allow the probe to horizontally pass through, wherein the wash nozzle is positioned within the basin such that the side slits are centered on the path of the probe ; a basin comprising an elongate body with an opened first end sized to receive and secure the wash nozzle therein; wherein the vertically-elongate cavity is configured to fill with fluid to clean the probe, a geometry of the vertically-elongate cavity allowing the wash nozzle to fill to a predetermined level while waste fluid flows out through the opposing side slits ; and wherein the basin is configured to capture the waste fluid dispensed by the probe and the wash nozzle , wherein the geometry of the vertically-elongate cavity comprises a bottom portion and a top portion , the top portion vertically expanding from a tapered region to a flared region with a top opening at a top end, the bottom portion vertically tapering to a bottom end comprising a bottom opening , wherein the waste fluid further flows out through the bottom opening, and wherein the wash nozzle further comprises a fluid inlet port connected to the vertically-elongate cavity , the fluid inlet port configured to fill the vertically-elongate cavity with the fluid to clean the probe , wherein the fluid inlet port is connected to a first side portion of the vertically-elongate cavity and is located at a point below a nominal level of the probe when inserted through one of the side slits into the vertically-elongate cavity for cleaning. <EOS>
