Mercury Labs is a research company located in Central City.
A doctor is greeted by a security guard named Jimmy. Jimmy intriguingly asked what he was working on but the doctor only gave an answer of mystification by saying "the future." An alarm buzzed in the facility, and the patrolling guards have the doctor get to safety. The Reverse-Flash killed both of the guards instantaneously. He appeared in front of the door, staring menacingly at the doctor.
After losing her husband, Ronnie Raymond, Caitlin Snow chose to work at Mercury Labs because staying at S.T.A.R. Labs reminded her too much of her loss. Cisco Ramon visited her for some help in regards to "Atom-Smasher". Later, Barry Allen also paid Caitlin a visit. They watched a video Eobard Thawne left for Barry, and witnessed his confession of murdering Nora Allen.
The Mercury Labs facility was destroyed by Black Siren during the Metapocalypse when Zoom brought his loyal followers to Earth-1. Fortunately, the Flash was able to help evacuate all the occupants.
In the year 2048 in the timeline where Nora West-Allen came from, Mercury Labs recruited August Heart as an intern. However, Heart was later fired due to administering tachyons on 17 comatose patients.
