Active isolation table ensures complete isolation from vibrations while combining excellent stability. A top plate sits over the isolation table and has an isolation area of 35x55cm built in for the microtome. Larger isolation areas that are available gives you a surrounding worktop that can be used for placing equipment on and for work without disturbing the microscope. The damped rolling diaphragm isolators have a low natural frequency of 2Hz which effectively isolates out vibrations above 6Hz, well below the frequencies at which typical building vibrations begin to occur.
