Abstract:
The closure has a locking ring (7) connected to an internally threaded collar (8) at a frangible annular portion (10), which can be ruptured to gain immediate access to the contents of a container. A stopper member (20) is fixed to the threaded collar (8) for selectively connecting the closure (1) to an anaesthetic transfer device. A discharge passage (23) and a venting passage (24) extend through the stopper member (20) for communication with a container (3) engaged by the threaded collar (8). A first pierceable diaphragm (25) is located within and occludes the discharge passage (23), and second pierceable diaphragm (29) is located within and occludes the venting passage (24).
Abstract:
An automated, continuous and random access analytical system, having apparatus and methodology capable of simultaneously performing multiple assays of liquid samples using different assay methodologies, and providing continuous and random access while performing a plurality of different assays on the same or different samples during the same time period, is disclosed. A method is also disclosed of operating an automated continuous and random access analytical system capable of simultaneously effecting multiple assays of a plurality of liquid samples wherein scheduling of various assays of the plurality of liquid samples is followed by creating a unit dose disposable and separately transferring a first liquid sample and reagents to a reaction vessel without initiation of an assay reaction sequence, followed by physical transfer of the unit dose disposable to a processing workstation, whereby a mixture of the unit dose disposable reagents and sample are achieved during incubation. The system is capable of performing more than one scheduled assay in any order, and assays where more than such scheduled assays are presented. The automated, continuous and random access analytical system is also capable of analyzing the incubated reaction mixtures independently and individually by at least two assay procedures.
Abstract:
A novel process for preparing enantiomerically-pure 3-methyl-5-(1-(C1-C3-alkyl)-2-pyrrolidinyl)isoxazole in high yield, wherein a protected pyrrolidine or 2-oxo-pyrrolidine starting material is reacted with a suitable organic anion and a resulting beta-keto oxime intermediate is cyclized and dehydrated, as well as intermediates useful in the preparation thereof.
Abstract:
The present invention provides a tetrahydroisoquinoline compound of formula (I) or a pharmaceutically acceptable salt thereof which is an antagonist for alpha-2 adrenoreceptors and/or which inhibits biogenic amine uptake.
Abstract:
An apparatus for pipetting a specimen with a nozzle, which can detect not only complete but also incomplete closure of the nozzle. A pressure of an air hose (12) connected to a nozzle (10) for sucking a specimen is detected by a pressure sensor (20) and its detection value is sent to a closure detection portion (26). A plurality of pressure calculation periods are provided to the closure detection portion (26) and a pressure difference in each of the calculation periods is calculated. When a pressure difference exceeds a predetermined threshold value corresponding to each calculation period in that calculation period, a closure alarm is raised. Since a plurality of pressure calculation periods are set, incomplete closure can also be detected besides complete closure, and a pipetting accuracy can be improved.
Abstract:
The present invention discloses novel immunogens, antibodies prepared from such immunogens, and labeled reagents useful in immunoassays for the detection and quantification of testosterone in a test sample. Also disclosed are immunoassays using these reagents and methods for synthesizing these reagents. The immunoassays are preferably microparticle enzyme immunoassays (MEIAs) and fluorescence polarization immunoassays (FPIAs). Further discloded are novel starting materials for making the above novel immunogens and labeled reagents. Methods for making the novel immunogens and labeled reagents from the novel starting materials are also disclosed.
Abstract:
A sample container holder (18) is provided for gripping a sample container (34) which contains a sample. The sample container holder (18) comprises a body (42) having a bore (60) for receiving a sample container (34). A flexible element (82) is disposed within the bore (60). A fluid passage is operatively connected with the flexible element (82) for supplying a fluid to the flexible element (82) such that, when the sample container (34) is received in the bore (60) in the body (42) of the sample container holder (18), the flexible element (82) engages the sample container (34) with a conforming, cushioning compression of sufficient magnitude to resist removal of the container (34) from the bore (60). A method of holding a container with a container holder is also provided comprising the following steps. The container is received within a bore on the container holder, and a fluid is conveyed through a fluid passage operatively connected with a flexible element within the bore such that the flexible element engages the container to retain the container within the bore.
