Universal Fluid Cell
A Universal Fluid Cell is a fluid container, similar to a bucket but stackable, and is a replacement for the legacy Empty Cell.
Universal cells are capable of holding up to 1000 mB of any fluid, though if not completely full they cannot be stacked with other full cells. This does however allow for transfer of smaller amounts of fluid, such as the UU-Matter produced by the Replicator.
Unlike the old Empty Cells, universal cells are reusable when placed in machines and will appear in any relevant output slots once their fluids have been extracted.
