The title says 120cc but the description says 30cc which is it???

it is 4oz. So the bottle it comes in is about 3 inches tall and approximately 1-3/4 inches in diameter. hope that helps.

Can I used it in a magnetic vacuum seal?

The EFH-1 type listed here is not recommended for use in speakers and I would guess that EFH 1 would not have the correct viscosity for use in seals.

What is the size of the nanoparticles in nm? Can you wash off the oil and resuspend in water?

i don't remember what the size was, although 4 nano meters comes to mind. If you removed the oil and tried to suspend them in water, the particles would oxidize(being exposed to oxygen) and would gather together into redish clumps. All the smooth fluidity would be no more.

Is this an authentic ferrotec fluid? what is the model number for it? amgxxx emgxxx etc etc etc

Yes, .. this efh1... part number is 92u40000000 / lot number v121021a.. this educational FF.. not for speakers etc
