The Alchemy Lab of Babylon (バビロンの「錬金棟」,Babiron no "Renkintō"?, literally "Alchemy Building of Babylon") is one of the nine legacies left behind by the genius doctor Regina Babylon. It was created during the period of the ancient Partheno Civilization approximately 5000 years ago. It was discovered by Touya Mochizuki and is managed and controlled by the gynoidBell Flora. It is the third part of Babylon to be discovered 
The Alchemy Lab of Babylon serves the the medical center for the combined Babylon. It is capable of healing both minor and major injuries by placing the person in a special medical capsule. This process is capable of regenerating lost limbs and other body parts in a matter of hours or days depending on the severity of the injury in question.  This facility is also utilized by Touya Mochizuki in the production of Ether Liquid (the power source for the Frame Gears). The Alchemy Lab is primarily used to produce new types of medicine and agricultural products such as rice by combining various materials and magic together. The products that are produced by the Alchemy Lab can be enhanced to become resistant to plagues and other natural phenomena. Also by combining the functions of the Alchemy Lab and the Research Laboratory it is possible to create a clone of a particular person by a genetic sample of that person. It also has the ability to compare the DNA of two individuals to confirm if they are related or not.
It's teleportation circle is located in the arctic Kingdom of Elfrau located to the far north of the continent. It was located in an ice cave to the far north of the kingdom. The circle itself was placed inside a large black luster relic that was covered in magical ice preventing intruders from entering even with magic. The entrance to the circle is located at the top of the relic.
The Alchemy Lab was mainly used by Doctor Babylon to produce various types of drugs and potions, all of which had a sexual nature (love potions, aphrodisiacs, stimulants, etc).
The Alchemy Lab is primarily used by Touya to make antidotes, recovery potions & food products (such as rice and vegetables) to help aid his country's growth.
