Cartridge for purification of biological samples

The present disclosure provides a cartridge for purifying biological samples. The cartridge comprises a first chamber configured to receive and hold biological samples, and at least one second chamber configured to receive and hold a reagent solution. A first fluid flow control valve is fluidly connected to outlet ports of the first chamber and the at least one second chamber. Also, the first fluid flow control valve is fluidly connected to a matrix chamber and is configured to selectively route biological samples and reagent solution into the matrix chamber for purifying the biological samples. A binding matrix is configured in the matrix chamber for capturing the nucleic acids from the biological samples and the reagent solution. Further, a elute collection chamber is fluidly connected to the matrix chamber, wherein the elute collection chamber is configured to receive and hold purified biological sample from the matrix chamber.
