pylabrobot.liquid_handling.liquid_handler.LiquidHandler.drop_tips#
- async LiquidHandler.drop_tips(tip_spots: List[Union[pylabrobot.resources.tip_rack.TipSpot, pylabrobot.resources.resource.Resource]], use_channels: Optional[List[int]] = None, offsets: Union[pylabrobot.resources.coordinate.Coordinate, List[Union[pylabrobot.resources.coordinate.Coordinate, pylabrobot.default._DefaultType]], pylabrobot.default._DefaultType] = Default, allow_nonzero_volume: bool = False, **backend_kwargs)#
Drop tips to a resource.
Examples
Dropping tips to the first column.
>>> lh.pick_up_tips(tip_rack["A1:H1"])
Dropping tips with different offsets:
>>> lh.drop_tips( ... channels=tips_resource["A1":"C1"], ... offsets=[ ... Coordinate(0, 0, 0), # A1 ... Coordinate(1, 1, 1), # B1 ... Coordinate.zero() # C1 ... ] ... )
- Parameters
tips – Tip resource locations to drop to.
use_channels (Optional[List[int]]) – List of channels to use. Index from front to back. If
None
, the firstlen(channels)
channels will be used.offsets (Union[pylabrobot.resources.coordinate.Coordinate, List[Union[pylabrobot.resources.coordinate.Coordinate, pylabrobot.default._DefaultType]], pylabrobot.default._DefaultType]) – List of offsets for each channel, a translation that will be applied to the tip pickup location. If
None
, no offset will be applied.allow_nonzero_volume (bool) – If
True
, the tip will be dropped even if its volume is not zero (there is liquid in the tip). IfFalse
, a RuntimeError will be raised if the tip has nonzero volume.backend_kwargs – Additional keyword arguments for the backend, optional.
tip_spots (List[Union[pylabrobot.resources.tip_rack.TipSpot, pylabrobot.resources.resource.Resource]]) –
- Raises
RuntimeError – If the setup has not been run. See
setup()
.ValueError – If no channel will pick up a tip, in other words, if all channels are
None
or if the list of channels is empty.ValueError – If the positions are not unique.
ChannelHasNoTipError – If a channel does not have a tip.
TipSpotHasTipError – If a spot already has a tip.
