columns=['a', 'b', c'] should be columns=['a', 'b', 'c']

Another minor typo is in the "Working with Recipes" user guide section:

PyPlate/docs/source/users_guide/working_with_recipes.rst

Line 292 in f2047cc

print(plate.volumes(unit='uL'))

This function was renamed from 'volumes()' to 'get_volumes()', so the code doesn't run as written. After changing it, I could run the example without issue.

EDITED TO ADD: There's a couple more I found in the "Usage Tracking" user guide section:

PyPlate/docs/source/users_guide/usage_tracking.rst

Line 79 in f2047cc

>>> recipe.substance_used(substance=water, destinations=[container], unit='mol')

PyPlate/docs/source/users_guide/usage_tracking.rst

Line 85 in f2047cc

>>> recipe.substance_used(substance=water, destinations=[stock_solution], unit='mmol', timeframe='stage 1')

The function 'substance_used()' was renamed to 'get_substance_used()', so the code doesn't run as written. It runs when making the proper renaming adjustment.

The description after the second call also seems to be inaccurate. The call seems to be specifically looking at the water used during ''Stage 1" rather than the entire recipe as the description states, and the amount of water that is used (1704.673 mmol) is different than the amount stated in the description (1051.034 mmol).
