1. An apparatus configured to extract and amplify nucleic acid from a plurality of nucleic-acid containing samples, comprising:
- a rack comprising a plurality of lanes, each lane of the plurality of lanes comprisinga first location configured to receive one of the plurality of samples, anda second location configured to receive a reagent holder;
an integrated separator and heater comprisinga magnetic separator configured to move adjacent to one or more of the second locations of the rack; and
a heater assembly comprising a plurality of independently controllable heater units, each heater unit shaped and sized to accept a single process chamber of a reagent holder, each heater unit configured to apply heat independently of any other heater unit in the heater assembly;
a liquid dispenser movable from a first position above one of the first locations to a second position above one of the second locations; and
a bay comprising at least one heat source and configured to receive a microfluidic cartridge comprising a plurality of lanes, the bay configured to interact with the cartridge to separately amplify nucleic acid extracted from the plurality of samples by applying heat to each lane individually.

Abstract
The technology described herein generally relates to systems for extracting polynucleotides from multiple samples, particularly from biological samples, and additionally to systems that subsequently amplify and detect the extracted polynucleotides. The technology more particularly relates to microfluidic systems that carry out PCR on multiple samples of nucleotides of interest within microfluidic channels, and detect those nucleotides.
