For table applications that require isolating over 350 lbs (160 kg) of net load, we recommend our 68-500 Series tables. They are similar in design to our 63-500 Series tables, with higher capacity isolators and a more massive stainless steel top plate.

In addition to high load applications, 68-500 Series tables are also recommended for payloads with unusually high centers of gravity and equipment with moving stages. These applications should benefit from the increased stability of the 68-500 design.

With a stiffer, more massive top plate, a lower natural frequency isolator, and stiffer, heavier leg frames,
68-500 Series tables provide performance that is markedly superior to any other passive table 
in the industry.
