As the title suggests, i'm not sure how to make the big lab use the liquid science itself, unless it's not possible. And my second point to this is, if it cannot use liquid science, how do you make the liquid back into a vial? because the recipe looks like you put it back into a chemical plant, but it doesn't seem to work.

hi Furry... Labs really doesn't accept fluids, but i wanna do a thing like a Frankenstein monster, and put several machines in one, but invisible, making in a way that feels that we using the fluid, but it is converting....

But about the error, the recipe for "solidify" doesn't working?

I'm also running with Bob's Mods and Angels, that may be causing problems. Also, am I understanding the recipe wrong, or is it melt 1 gear, and 1 copper plate, makes 10 liquid. then you can turn 1 liquid into 1 science bottle, or does it take all 10 liquid?

No it was user error, I was looking at the wrong recipe that's my fault. I just did some testing. And I answered my above question too, it takes the full 10 liquid science.
