Seperate oil from liquid???

Does anyone know what is the thing that drops into the liquid and seperate the oil, into a yellow solid in the bottom?
Can we buy it publicly?

Answer:
Can you give any more details? Where have you seen it used, or how did you find out about it?

At first glance, I don't know. There are various solid substances through which oil-water emulsions may be poured... and it filters out the oil. You might look up "oil solidification" or something similar on the 'net.
centrifuge------maybe
if the boiling point of the oil is higher than th ewater, you can just evaporate off the water.


if you put it into a separatory funnel, or this buret (for only a small amount of liquid, you can separate it with a buret.
Try SOAP solution--right now. I have seen it work.
