Abstract: An apparatus for measuring the luminescence and the fluorescence of a sample, comprising: a light tight optics box capable of receiving a pipette tip containing a sample; an optical sensor located within the optics box and capable of being disposed in both a luminescence reading position and a fluorescence reading position; an excitation light fiber optic bundle and a sample transmission fiber optic bundle; an excitation light assembly that projects excitation light onto a first terminus end of the excitation light fiber optic bundle; and an in-line filter located along the sample transmission fiber optic bundle.

Abstract: A three-phase suspension suitable for use as an erythrocyte sedimentation rate (ESR) control having the following three components: (1) a synthetic plasma base, (2) an aggregating agent such as a high molecular weight polymer or combination of high molecular weight polymers, and (3) chemically fixed mammalian red blood cells. The control is designed to allow the user to monitor the accuracy and precision of analytical methods for determining the sedimentation rate of human erythrocytes in whole blood specimens. Chemical fixing of the red blood cells provides the ESR control with the capability of providing useful results in the presence of citrate and/or saline.

Abstract: The invention discloses antigenic compositions and an assay for detecting Helicobacter pylori. The antigenic composition includes a comprehensive mixture of fragments purified from Helicobacter pylori for the detection of Helicobacter pylori infection and/or for monitoring the status of such an infection following treatment. The assay involves an ELISA for urine samples, and includes a kit wherein the antigenic composition is immobilized on a solid support.

Abstract: A method of forming an eroded pattern on a metal part using Electrical Discharge Machining (EDM) comprising: forming a pattern of electrodes on the end of a piece of electrode material by using wire EDM, the pattern of electrodes being the pattern to be eroded on the metal part or being a portion of the pattern; and mounting the metal part for EDM with the pattern of electrodes being mounted for use as electrodes and the erosion of the pattern or portion of the pattern provided by the pattern of electrodes by EDM in the metal part.

Abstract: A microscope inspection slide including at least one examination chamber formed by bonding together a base plate and a cover plate. The base plate having a chamber floor surface raised above a deck surface on the base plate, and the cover plate having a roof surface with a depth control ridge positioned about a portion of the edge of the chamber roof surface. Bonding the cover plate to the base plate forms an examination chamber with the distance between the roof surface and floor surface maintained constant, and entrapped gases and excess fluid allowed to drain from the examination chamber through notches in the depth control ridge.
