QPix Utility Processes

Manage Sanitise Profiles sets up various Sanitise profiles as required by various
experimental needs. You must have a minimum of one Sanitise profile created before you
can successfully do a picking routine. See

Creating and Editing Sanitise Profiles on page

Camera Alignment Process calibrates and correctly aligns the camera to get pin-to-spot
precision, relating the image pixel co-ordinates with the instrument x and y coordinates. Do
this process whenever the head is returned to the actuator or whenever the actuator is hit,
as this can have a negative effect on picking precision. See

Aligning the Camera on page

Instrument Utilities lets you do several maintenance and cleaning activities.
Manage Petri Dish Holders allows you to set either an original source-holder tray or a new
spring-loaded adjustable holder tray as the default source-holder tray per source holder
tray type, such as OmniTray, 1-way, 4-way, or 5-way petri dish holders. Only one style per
holder type can be set as the default, either the original style, or the adjustable style.

Maintenance Processes

Note: Molecular Devices recommends that only trained personnel configure these
settings.
