pylabrobot.opentrons.flex.flex_head.FlexHead8.liquid_probe

async FlexHead8.liquid_probe(plate: Plate, column: int) → float

Probe for liquid in a column – one liquidProbe command anchored at its rearmost well; return the found liquid z (mm).

Requires at least one mounted tip and a valid column (both checked before any wire command) and ALL nozzle mode (reset first if a single-tip op left the layout otherwise). Raises OpentronsError if no liquid is found; use try_liquid_probe for the non-raising variant.

Parameters:

• plate (Plate)

• column (int)

Return type:

float
