The microscopes are housed in specially built sound proof rooms, with each microscope placed on a concrete slab that extends to Manhattan bedrock or on a customized vibration table. This construction allows the instruments to be isolated from vibrations or other disturbances commonly found in the city. The walls are sand-filled to keep the rooms quiet. An air conditioning system with duct socks produces near laminar flow, and wall padding minimizes perturbations. The Krios and Helios rooms are additionally fitted with Electro-Magnetic isolation systems.
