A fluorometer for measuring the fluorescence of a material in an open top microtest well comprising support means for supporting the structure defining said well, a source of exciting light, first means for passing a beam of said exciting light downwardly through the open top of said well to strike

A fluorometer for measuring the fluorescence of a material in an open top microtest well comprising support means for supporting the structure defining said well, a source of exciting light, first means for passing a beam of said exciting light downwardly through the open top of said well to strike and fluorescently excite the material in said well when said well is positioned at a preselected location on said support means, a photo-detector, and second means for directing the light which is emitted by the fluorescently excited material and which passes upwardly through the open top of the well to said photodetector for detection thereby, said first means including a lens for focusing said beam on a spot within said well.
