- This page is about the Essentia Buffer added by Thaumcraft 4. For other uses, see Essentia Buffer.
The Essentia Buffer is a block added by Thaumcraft 4. It is an improved Essentia Tube that can store 8 units of essentia of different types simultaneously without fear of creating Flux Gas. It has very low suction (and thus not highly prioritized when taking in essentia), though it can be improved by attaching Arcane Bellows to it.
The alchemical centrifuge is a wondrous invention that allows you to break essentia into its component parts.
When compound essentia flows into the centrifuge from below it will be slowly broken down into the primal or compound essentia that it is made from. Only one of the components is created for each point of essentia broken down.
The resulting essentia needs to be drawn from the top of the centrifuge. Because of the idiosyncrasies of the tube pressure system, it would be best to connect a Essentia Buffer to the top of the centrifuge.
The essentia buffer allows you to store a limited amount of essentia - 8 points total, though it can be made up of any combination of essentia types. Like a jar it has suction, though it applies the minimum amount of suction possible (1).
This means that is usually only able to draw essentia from an essentia source it is directly attached to. However tubes can be connect to all its sides, meaning that it is invaluable for getting essentia out of devices like the centrifuges that could contain variable types of essentia.
You can attach bellows to the buffer - each attached bellows increases its suction by 32.
Additionally you can toggle individual connections on and off as with a normal tube, but if you shift click a connection, it will choke the suction back to 1 (blue band) or 0 (red band) on that side.
This allows for some interesting possibilities when routing essentia.
