Abstract

A liquid sample dispenser for use with an optical analysis disc. The dispenser includes a body portion, a tip portion connected to the body portion, first and second retainer members moveably supported within the tip portion, and a sealant contained between the first and second retainer members. One of the retainer members also functions as an inlet stopper. The associated optical analysis disc includes a substrate and a channel layer associated with the substrate. The disc further includes a cover portion located so that the channel layer is positioned between the substrate and the cover portion. An inlet port formed in the cover portion is adapted to receive a test sample from the tip portion of the dispenser. The sample is loaded form the dispenser into the disc followed by the inlet stopper and sealant to seal the sample in the disc. Related methods for loading a biological sample into the analysis disc through the dispenser, and sealing the disc inlet are also provided. Kits including the disc and dispenser or the disc and one-use dispenser tips are also provided.
