Warning
DO NOT use Test Chip B in the LabChip GX Touch/GXII Touch.
Putting Test Chip B into the LabChip GX Touch/GXII Touch
instrument will cause permanent damage to the instrument.
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 7 voltage channels for the LabChip GX Touch/GXII Touch chips.
HV channels can be run in either constant voltage or constant
current mode.
Lid Holds the electrodes and o-rings to supply voltage and
pressure to the chip.
Chip Interface Holds the chip. The sipper on the chip extends through the
sipper slot.
Optics lens Lens for laser to illuminate chip.
Optical Beam
Dump Provides an optically dark background under the chip.
Pressure Plate with
Heating Element Maintains a constant temperature in the chip’s microfluidic
channels.
Electrodes Apply voltage to the chip to move fluid through the chip and
drive electrophoretic separations in the chip channels.
O-Rings Create a seal between the chip interface lid and the chip to
apply pressure or vacuum to the wells.
Pressure Port Supplies pressure (positive or negative) to prime the chip or
move samples through the chip.
