Centrifuges

PyLabRobot supports the following centrifuges:

• VSpin

Centrifuges are controlled by the Centrifuge class. This class takes a backend as an argument. The backend is responsible for communicating with the centrifuge and is specific to the hardware being used.

from pylabrobot.centrifuge import Centrifuge
backend = SomeCentrifugeBackend()
pr = Centrifuge(backend=backend)
await pr.setup()

The setup() method is used to initialize the centrifuge. This is where the backend will connect to the centrifuge and perform any necessary initialization.

The Centrifuge class has a number of methods for controlling the centrifuge. These are:

• open_door(): Open the centrifuge door.

• close_door(): Close the centrifuge door.

• lock_door(): Lock the centrifuge door.

• unlock_door(): Unlock the centrifuge door.

• lock_bucket(): Lock centrifuge buckets.

• unlock_bucket(): Unlock centrifuge buckets.

• go_to_bucket1(): Rotate to Bucket 1.

• go_to_bucket2(): Rotate to Bucket 2.

• rotate_distance(): Rotate the buckets a specified distance (8000 = 360 degrees).

• start_spin_cycle(): Start centrifuge spin cycle.

Start spin cycle:

await cf.start_spin_cycle(g = 800, duration = 60)

VSpin

The VSpin centrifuge is controlled by the VSpin class.

from pylabrobot.centrifuge import Centrifuge, VSpin
cf = Centrifuge(name = 'centrifuge', backend = VSpin(bucket_1_position=0), size_x= 1, size_y=1, size_z=1)
