Abstract

A fluid circulator and temperature regulator apparatus for use in an electrophoresis process with a sequencing cell including a cooling jacket having an inlet and an outlet, the apparatus comprising an inlet adapted to be connected to the cooling jacket outlet, an outlet adapted to be connected to the cooling jacket inlet, a reservoir having an inlet, an outlet and a vent, a heat exchanger having an inlet and an outlet, a pump having an inlet and an outlet, the reservoir, the heat exchanger and the pump being fluidly connected in a flow path having an upstream end and a downstream end, with the reservoir being downstream of the pump, and valves operable in a first mode for connecting the downstream end of the flow path with the outlet port and for connecting the inlet port with the upstream end of the flow path, and operable in a second mode for connecting the downstream end of the flow path with the upstream end the flow path internally of the apparatus such that fluid flows from the downstream end of the flow path to the upstream end of the flow path without flowing to the outlet.
