  • Microplate assembly and method of preparing samples for analysis in a microplate assembly
    Patent number: 5961926
    Abstract: A microplate assembly for use in analyzing samples captured on a filter medium comprises a carrier plate, a holding tray, a collimator, and a cover film. These elements are generally rectangular in shape and are sized to stack on top of one another. The holding tray is positioned within the carrier plate, the collimator and filter medium are positioned within the holding tray with the filter medium positioned beneath the collimator, and the cover film is sealed over the collimator. To prepare samples in the microplate assembly for analysis, the samples are captured on the filter medium and the filter medium is placed in the holding tray. After adding scintillation cocktail or luminescent substrate to the filter medium, the collimator is placed over the holding tray with the filter medium positioned between the collimator and the holding tray and the samples disposed in the sample wells.
