Pipette Tip, Pipette, Apparatus and Kit for Light Measurement

A pipette tip which comprises a vessel for attachment to a pipette, wherein the vessel is prefilled with a reagent or chemical to permit an assay to be carried out in the pipette tip itself and wherein the pipette comprises a body portion for aspirating a fluid sample into the pipette tip when attached thereto, the body portion comprising at least one light source, or at least one entry point for light from at least one light source, providing an optical path of light that passes through the sample in a direction essentially along the longitudinal axis of the pipette tip.

A method for measuring light output from a fluid sample and reagent, comprising providing a pipette tip or capillary tube having first and second open ends with the sample and reagent to be analysed contained therein, detecting light output from an open end of the pipette tip or capillary tube, wherein the sample is drawn into the pipette tip in a number of steps, and shining a light longitudinally through the pipette tip during the step process to obtain a calibration curve of the light detected.

A kit for light measurement, comprising a prefilled pipette tip or capillary tube for containing a fluid sample to be analysed, the pipette tip or capillary tube having first and second open ends, and light output guide means for guiding light output from at least one open end of the pipette tip or capillary tube to a photo detector.
