First of all, they're not mandatory. You can do what you have to do without the canisters and the whole mad scientist stuff.
Then, there is no magic trick to get them all, you just have to look everything you can find in deep caverns, everywhere.
Last but not least, you don't need them all to make the Exitus-1 sequence. Just scan what you have and try to build the sequence to mimic Exitus-1. I needed only 4 of them to do so. I can't tell you wich you'll need, as it seems reagents and sequences change from one game to another. <-Spoiler

All of that assumes the OP is looking for the mutagen reagents' canisters, but I would hazard a guess that they are looking for the hydraulic fluid canisters.

Well, about that, here are all four of them in spoilers (you need three):

1. One is in the locked warehouse in the warehouse block. You need to find a way to power the electronic lock to be able to open the door.

2. In fact, there is another one right there.

3. The Tchortists will reward you with one if you rescue their hostages, which will probably require you to demolish the Faceless camp - I'm not sure if you can do it if you are friendly with the Faceless already, but if you have accepted the mission before talking to their commander they will kill you.

4. A much easier option is just exploring south and west of Caerus Residential (where the statue is), there should be a ruined building with burrowers getting high on hydraulic fluid. Maybe you'll still find some left over.
