Abstract: Methods for the detection and/or quantification of a biological material in a sample. The method includes the steps of liquefying the sample (if necessary) and pouring the liquefied sample into the incubation vessel. The incubation vessel has a generally flat horizontal surface and the surface is divided into at least one incubation site. Each incubation site is adapted to hold an aliquot of liquid and is sized and shaped, and formed of a suitable material, to hold the aliquot within the well by surface tension. Any excess liquid from the liquefied sample is poured from the surface of the incubation vessel. The method then involves incubating that incubation vessel until the presence or absence of the biological material is determined. The presence of air bubbles can be dramatically reduced by the presence of a surface acting agent in the liquid sample deposited on the device surface.

Abstract: A self-contained signal generating device and methods for using and making the same are provided. The device and methods may detect the presence of a number of different substances, such as proteins, and utilizes a target material binding dye, which may precipitate a target material as well as stain it, and/or undergo a detectable change, e.g., an absorption or emission frequency shift, on binding of the substance to be detected.

Abstract: Method for detection of a biological material in a sample. The method includes the steps of liquifying the sample (if necessary) and pouring the liquified sample into the incubation plate. The incubation plate has a generally flat horizontal surface and the surface is divided into a plurality of at least 20 recessed wells. Each well is adapted to hold an aliquot of liquid and is sized and shaped, and formed of a suitable material, to hold the aliquot within the well by surface tension. Any excess liquid from the liquified sample is poured from the surface of the plate. The method then involves incubating that incubation plate until the presence or absence of the biological material is determined.

Abstract: Method and assay devices for the detection of the presence or amount of biological material, analyte(s), or microorganism(s) in a sample. The method includes the steps of liquefying the sample (if necessary) and distributing the liquefied sample over the surface of the assay device. The device may comprise an incubation plate, a dip stick device, or other devices. The devices have at least one reagent provided within the devices. Some devices have a generally flat horizontal surface which is divided into a plurality of recessed wells. Others have one or more surfaces with reagent island(s) immobilized thereon. Each well or reagent island is adapted to hold an aliquot of liquid. The wells or reagent islands are sized and shaped, and formed of a suitable material, to hold the aliquot within the well or reagent island by surface tension. Any excess liquid from the liquefied sample is drained from the surface of the device.

Abstract: A self-contained incubator for growth of microorganism kit and methods for use of such a kit are provided. The kit and methods may detect the presence of microorganisms and may utilie a microorganism growth and indicator medium provided in a sample container along with a heat source, preferably generating heat through chemical means, and optionally heat shields, allowing for on-site testing of a microorganism present in a sample. The sample container may also include a removable vessel cap that includes a barrier separating the sample from a material capable of disinfecting the sample, thereby preventing contact of the sample and the material for a desired time period. The vessel cap may also be used independently in other applications.

Abstract: An article adapted for holding a liquid sample for quantification of biological material in the liquid sample. The article includes a bag having an upper surface sheet and a lower surface sheet enclosing a volume therebetween. The bag has an upper opening through which the liquid sample can be poured into the volume in the bag. The bag also has a plurality of partitions configured to separate one or more portions of adequate sample in the bag. Also provided is a passage through which a liquid sample can be distributed throughout the volume in the bag. The bag is made of material which can be caused to form discreet non-permeable compartments for holding separate aliquots of the liquid sample.

Abstract: A threaded temperature indicating plug for hot oil containing housings such as vehicle transmissions and the like that can replace the standard oil level plugs of the same and as well afford a plug that from which the temperature at which the oil may have overheated will be recorded and whether there is a definite need to change the oil in the transmission. Liquid crystal areas are provided on an indicator label that is fixed to the plug bolt shank in a liquid-tight manner by a fixed covering and for direct contact with the oil body or a splash from oil at a lowered level.
