This is achieved once you have completed the challenge near the end of Chapter 7 in which you first encounter the Conversion Gel.

EDIT: Thanks to Offscauta for pointing out that the achievement can be missed if you don't complete the level in the correct way. Make sure you use the portals to jump up to the large grilled area down the stairs from the exit to finish the level.
