Flow-based thermocycling system with thermoelectric cooler
First Claim
1. A thermocycling system for performing a flow-based reaction on a sample in fluid, comprising:
- a thermally conductive core configured as a heat source and a heat sink;
a plurality of segments surrounding and discrete from the core and defining at least two temperature regions;
a plurality of heating elements configured to maintain each temperature region at a different desired temperature, at least one of the heating elements being a thermoelectric cooler disposed between the core and one of the segments and configured to transfer heat between the core and the one segment; and
a fluid channel extending along a helical path that passes through each temperature region multiple times such that fluid flowing in the channel is heated and cooled cyclically.

Abstract
Thermocycling system, including methods and apparatus, for performing a flow-based reaction on a sample in fluid. The system may include a plurality of segments defining at least two temperature regions, and also may include a plurality of heating elements configured to maintain each temperature region at a different desired temperature. At least one of the heating elements may be a thermoelectric cooler operatively disposed to transfer heat to and/or from a temperature region The system further may include a fluid channel extending along a helical path that passes through the temperature regions multiple times such that fluid flowing in the channel is heated and cooled cyclically.
