# Centrifuges

PyLabRobot supports the following centrifuges:

- {ref}`VSpin <VSpin>`

Centrifuges are controlled by the {class}`~pylabrobot.centrifuge.centrifuge.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.

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

The {meth}`~pylabrobot.centrifuge.centrifuge.Centrifuge.setup` method is used to initialize the centrifuge. This is where the backend will connect to the centrifuge and perform any necessary initialization.

The {class}`~pylabrobot.centrifuge.centrifuge.Centrifuge` class has a number of methods for controlling the centrifuge. These are:

- {meth}`~pylabrobot.centrifuge.centrifuge.Centrifuge.open_door`: Open the centrifuge door.
- {meth}`~pylabrobot.centrifuge.centrifuge.Centrifuge.close_door`: Close the centrifuge door.
- {meth}`~pylabrobot.centrifuge.centrifuge.Centrifuge.lock_door`: Lock the centrifuge door.
- {meth}`~pylabrobot.centrifuge.centrifuge.Centrifuge.unlock_door`: Unlock the centrifuge door.
- {meth}`~pylabrobot.centrifuge.centrifuge.Centrifuge.lock_bucket`: Lock centrifuge buckets.
- {meth}`~pylabrobot.centrifuge.centrifuge.Centrifuge.unlock_bucket`: Unlock centrifuge buckets.
- {meth}`~pylabrobot.centrifuge.centrifuge.Centrifuge.go_to_bucket1`: Rotate to Bucket 1.
- {meth}`~pylabrobot.centrifuge.centrifuge.Centrifuge.go_to_bucket2`: Rotate to Bucket 2.
- {meth}`~pylabrobot.centrifuge.centrifuge.Centrifuge.rotate_distance`: Rotate the buckets a specified distance (8000 = 360 degrees).
- {meth}`~pylabrobot.centrifuge.centrifuge.Centrifuge.start_spin_cycle`: Start centrifuge spin cycle.

Start spin cycle:

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

(VSpin)=

## VSpin

The VSpin centrifuge is controlled by the {class}`~pylabrobot.centrifuge.vspin.VSpin` class.

```python
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)
```
