Chip Loader and Chip Eject Button
The chip loader extracts the chip from the cartridge and inserts the chip into
the optical unit where interactions occur.
Press Chip Eject to eject the chip from the optical unit back into the cartridge
for removal from the instrument.
An LED on the button indicates the chip loader status. Chip Eject is active
only when the instrument is in the Ready state. In the Ready state, the system
is prepared to start an experiment, maintain temperature control, and direct
buffer to all channels at the default flow rate. Shown above is the Chip Eject
button with LED indicator (left) and chip loader (right). A cartridge containing a
sensor chip is shown in the chip loader. The sensor chip inside the cartridge is
not visible.
Note: You can also eject the chip with ProteOn Manager™
software. See Inserting and Ejecting the Sensor Chip on page 76.
Buffer Control Buttons
Use the buffer control buttons to switch between the left and right buffer
bottles. Access the buttons by opening the door to the buffer compartment.
LEDs on the buttons indicate the status of buffer flow.
• Use the two buffer selector/flush buttons (Buffer A and Buffer B) to
select which bottle is the buffer source – left or right valve position,
