摘要:
A foam reducing or eliminating container for containing a liquid includes: a container body having a top portion, a bottom portion and an opening for adding a liquid to or removing a liquid from the container body; and a hollow baffle located within the container with first and second openings therein. The first and second openings are covered with a pierceable seal, wherein the first opening of the baffle is at least partially aligned with the opening of the container. In a preferred embodiment, the container is a reagent supply container for an automated analyzer, which includes: a container as described above; and a closure which is movable away from the opening of the container to be in an open position and movable into contact with the opening to be in a closed position. In another preferred embodiment a reagent supply for an automated analyzer includes: the reagent supply container as described above; and a liquid reagent therein. The second opening of the baffle is submerged in liquid. A method for reducing or eliminating the aspiration of foam into a metering probe includes: providing a reagent supply as described above; providing a metering probe movable in a direction toward and away from the reagent supply; moving the closure away from the opening of the container; piercing both seals covering the first and second openings of the baffle allowing liquid to enter the baffle from the end of the baffle submerged in the liquid, wherein the seals may or may not be pierced with the metering probe; moving the metering probe into the first opening of the baffle and into contact with the liquid in the baffle; aspirating a selected amount of liquid in the baffle; and moving the metering probe out of the baffle.
摘要:
Apparatus and a method for mixing a liquid within a disposable aspirating probe tip so that most of the liquid is forced to move past a transition zone between two different inside diameters to cause rotational mixing. The apparatus and method can be used to provide agglutination of blood, which in turn can be used for blood typing. The probe tip can comprise a single integral piece, or two separate portions. The transition zone can comprise a sharp demarcation between inside diameters, or a smooth one.
摘要:
The accurate determination of the presence of a fluid in a container is determined by assessing the difference in various pressure readings relative to a threshold value. The method distinguishes between actual aspiration of a fluid and aspiration of a film that can otherwise lead one to believe that fluid has been aspirated when it has not. The method is particularly useful in clinical analyzers such as automated enzyme immunoassay device

An apparatus for opening and closing a container (11) having a slidable shutter closure (15) moving past the apparatus, the apparatus includes: a rotatable shaft (31) having an axis perpendicular to the direction of travel of the slidable shutter, the shaft being biased against rotation in either direction; a driver (34) for bidirectionally moving the shaft from a position away from the container to a position in the vicinity of the container for opening and closing; and an extension (32) extending outwardly from the rotatable shaft along at least a portion of the shaft into a line of travel of the container, whereby the extension is adapted to engage the shutter closure of the container and move the shutter closure from an open position to a closed position or from a closed position to an open position.
