Tatiana will not be recruited if you choose to end the experiments.

Have the Experiments End to Receive Elixirs for Permadeath Mode

The elixirs you receive for letting the experiments end are rare and powerful items that revive an ally and heal them to 100% HP. These are extremely useful items when playing the True Zenorian Mode of the game. This is, of course, in exchange for not recruiting Tatiana.
