A transilluminator having a housing having therein a window, a first light source supported within the housing for transmitting light through the window and illuminating a sample adjacent the window, and a second light source which is mounted outside the housing and which is movable between a first position wherein the second light source is removed from the window, and a second position wherein the second light source is over the window for transmitting light onto a sample adjacent the second light source.

Dual light source transilluminator and method of transillumination

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.

Fluid circulator and temperature regulator

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 being adapted to be connected to the cooling jacket inlet and outlet, and the apparatus comprising a reservoir, a pump for circulating cooling fluid through the cooling jacket, and a heat exchanger for regulating the temperature of the cooling fluid, the apparatus being operable for filling and draining the reservoir, for degasifying fluid in the reservoir, and for filling and draining the cell.

Combined stacked temperature regulator, power supply and gel dryer for

Electrophoresis apparatus comprising an electrophoresis device including an electrophoresis chamber for containing a solid matrix electrophoresis medium and an electrically conductive fluid, a structure for establishing an electric field in the fluid and in the medium, and a structure including a Peltier element for circulating the fluid through the chamber and for removing heat from the fluid.
