async LiquidHandler.return_tips(use_channels: list[int] | None = None, allow_nonzero_volume: bool = False, offsets: List[Coordinate] | None = None, **backend_kwargs)

Return all tips that are currently picked up to their original place.

Examples

Return the tips on the head to the tip rack where they were picked up:

>>> await lh.pick_up_tips(tip_rack["A1"])
>>> await lh.return_tips()

Parameters:

• use_channels (list[int] | None) – List of channels to use. Index from front to back. If None, all that have tips will be used.

• allow_nonzero_volume (bool) – If True, tips will be returned even if their volumes are not zero.

• backend_kwargs – backend kwargs passed to drop_tips.

• offsets (List[Coordinate] | None)

Raises:

RuntimeError – If no tips have been picked up.
