Wrapper to allow Opentrons multichannel pipettes to use any number of tips

Project description

PipetteWrapper

PipetteWrapper is used to wrap opentrons multichannel Pipette objects to allow multichannels to act as single channels.

CURRENTLY REQUIRES A MODIFICATION TO LINE 67 IN opentrons/api/calibration.py:

CHANGE:

inst.pick_up_tip(container._container[0])

TO:

inst.pick_up_tip(location=container._container[0])

Example

from opentrons import labware, instruments
tip_rack = labware.load('opentrons-tiprack-300ul', slot='4')
pipette = PipetteWrapper(instruments.P50_multi(mount='left', tip_racks=[tip_rack]))
plate = labware.load('96-flat')
pipette.distribute(50, plate.wells('A1'), plate.wells('A2'), num_tips=4)  # Uses 4 tips
pipette.transfer(50, plate.wells('A1'), plate.wells('A2'))  # Defaults behaviour (8 tips)
