High Voltage Interface

Supplies DC voltage to the separation channels in the chip via inert
electrodes that are immersed in specific wells on the chip. There
are 6 voltage channels for the LabChip GX chips. HV channels can
be run in either constant voltage or constant current mode.

Window for laser to illuminate chip.
Provides an optically dark background under the chip.
Maintains a constant temperature in the chip's microfluidic
channels.
Apply voltage to the chip to move fluid through the chip and
drive electrophoretic separations in the chip channels.
Create a seal between the chip cartridge and the chip to apply
pressure or vacuum to the wells.
Supplies pressure (positive or negative) to prime the chip or
move samples through the chip.
Locks the chip cartridge closed.
