Abstract
Embodiments of the invention provide a filter kit including filters for processing a biological sample. Some embodiments include a filter cap in a tube kit with a first tube containing a buffer solution and a second tube containing a lyophilized master mix. Some embodiments include a method of processing a sample using the kit including mixing a biological sample in a first tube with the buffer solution, positioning the filter cap in the first tube, positioning a second tube on the filter cap, flipping the first tube, the filter cap, and the second cap to filter the biological sample and buffer solution mixture with the filter cap as it flows from the first tube to the second tube. Some embodiments include structure enabling transfer of materials through inline flow between the tubes. Some further embodiments include integrated structure for sample pulverization with integrated buffer and lyophilized master mix.
