Abstract: The present disclosure relates to sample processing device and associated methods of use. The sample processing device includes an internal chassis comprising one or more receiving chamber and one or more corresponding rows of buffer chambers operable to store a buffer liquid. The device also includes an external chassis having an actuator that is operable to actuate a piston.

When actuated, the piston causes the dispensation of fluid from the underlying buffer chambers to the corresponding receiving chambers. A valve is coupled to the internal chassis and operable to sequentially provide a fluid coupling between the respective receiving chambers and each buffer chamber of the corresponding rows of buffer chambers.
