Contamination detection systems, kits, and techniques are described for testing surfaces for the presence of hazardous contaminants, while minimizing user exposure to these contaminants. Even trace amounts of contaminants can be detected. A collection kit provides a swab that is simple to use, easy to hold and grip, allows the user to swab large areas of a surface, and keeps the user's hands away from the surface being tested. The kit also provides open and closed fluid transfer mechanism to transfer the collected fluid to a detection device while minimizing user exposure to hazardous contaminants in the collected fluid. Contamination detection kits can rapidly collect and detect hazardous drugs, including trace amounts of antineoplastic agents, in healthcare settings at the site of contamination.

Various apparatus, systems, and methods for measuring a solution characteristic of a sample comprising microorganisms are disclosed. The measured solution characteristic can be used to generate a standardized inoculum. In one embodiment, a sensor apparatus is disclosed comprising a sample container having a chamber lateral wall surrounding a chamber cavity configured receive the sample, a reference sensor fabricated as a container cap and comprising a reference electrode material and, and an active sensor made of a substrate covered in part by an active electrode layer. The active sensor can be coupled to at least part of the chamber lateral wall at a window opening defined along the chamber lateral wall. The solution characteristic can be measured using a reader configured to electrically couple to the sensor apparatus and measure the solution characteristic based on a potential difference between the active sensor and the active sensor.

Contamination detection systems, kits, and techniques are described for testing surfaces for the presence of analytes of interest, including hazardous contaminants, while minimizing user exposure to these contaminants. Even trace amounts of contaminants can be detected. A collection device provides a swab that is simple to use, easy to hold and grip, allows the user to swab large areas of a surface, and keeps the user's hands away from the surface being tested. The collection device also includes a test strip, and provides a closed fluid transfer mechanism to transfer the collected fluid from the swab to the test strip while minimizing user exposure to hazardous contaminants in the collected fluid. Contamination detection kits can rapidly collect and detect hazardous drugs, including trace amounts of antineoplastic agents, in healthcare settings at the site of contamination.

A door for a laboratory workstation is disclosed. The laboratory workstation has a horizontally extending work surface for providing a working area. The door is movable in relation to the work surface in a vertical direction perpendicular to the work surface between a safety position, in which the door closes the working area for manual access of a user, an access position in which the working area is open for manual access of a user, and a loading position.

A specimen cap. The specimen cap allows material to be transferred out of a specimen cup without exposing the user (clinician, lab tech, phlebotomist) to the sample. The cap employs a double cap system with a secondary cap providing access to a needle holder that holds a needle assembly. The needle assembly has an upward extending needle, with an optional needle cover, and a downward extending draw or sample tube extending downward to reach the sample contained in the specimen cup.

An embodiment of an assembly for isolating a substrate is described that comprises a vacuum source; a substrate; a receptacle configured to position the substrate and to operatively couple to the vacuum source; and a vessel configured to operatively coupled to the receptacle, wherein the substrate is configured to move from the receptacle to the vessel in response to a differential pressure applied by the vacuum source.

A reagent preparation device (also called sterile and safe reagent preparation device) is disclosed for preparing a solution of a reagent, particularly a toxic chemical. The sterile and safe reagent preparation device comprises a liquid storage for storing a liquid (solvent or other fluid reactant); and a reagent (chemical or other reactant) container for containing a reagent. The liquid storage and the reagent container are configured to be detachably engaged. A method of making the sterile and safe reagent preparation device and a method of using the sterile and safe reagent preparation device are also disclosed in the present application.

A Reagent container cap (116) is adapted to being mounted to a reagent container and to being adjustable, at least after an initial opening of the cap (116), between an opened state and a closed state, wherein the reagent container cap (116) defines a cap interior space (109) and has a cap opening (116o) allowing access to the cap interior space (109) from above when the cap (116) is in the opened state; and wherein, in the closed state of the cap (116), the cap interior space (109) is open only towards a bottom side (116b), wherein the reagent container cap (116) comprises a main portion (116m) and an insert portion (116i) that are fixedly connected to each other and made from different materials, wherein, when the cap (116) is in the closed state, the cap interior space (109) comprises a region (109t) which is delimited circumferentially and towards the upper side of this region completely and exclusively by surfaces of the insert portion (116i).
