LabChip GX Instrument Description 227Chip Cartridge (Continued)Figure 110. Lid LatchLidBottom of CartridgeOptical WindowOptical BeamDumpPressure Plate withHeating ElementElectrodesO-RingsPressure PortLid LatchHolds the electrodes and o-rings to supply voltage andpressure to the chip.Holds the chip. The sipper on the chip extends through thesipper slot.Window for laser to illuminate chip.Provides an optically dark background under the chip.Maintains a constant temperature in the chip’s microfluidicchannels.Apply voltage to the chip to move fluid through the chip anddrive electrophoretic separations in the chip channels.Create a seal between the chip cartridge and the chip to applypressure or vacuum to the wells.Supplies pressure (positive or negative) to prime the chip ormove samples through the chip.Locks the chip cartridge closed.High Voltage InterfaceSupplies DC voltage to the separation channels in the chip via inertelectrodes that are immersed in specific wells on the chip. Thereare 6 voltage channels for the LabChip GX chips. HV channels canbe run in either constant voltage or constant current mode.P/N 127170 Rev. 00 LabChip GX User Manual Caliper Life Sciences, Inc.
