BenchTop<br />
<strong>Compact</strong> <strong>Pneumatic</strong> <strong>Vibration</strong> <strong>Isolation</strong><br />
<strong>Platform</strong> <strong>with</strong> <strong>Self</strong>-<strong>Leveling</strong><br />
BenchTop <strong>Compact</strong> <strong>Vibration</strong> <strong>Isolation</strong> <strong>Platform</strong>s provide the rock solid performance and<br />
ultra-small packaging that is so critical to today’s life science and disk drive applications.<br />
Exclusive Stabilizer vibration isolation technology, adapted from our acclaimed<br />
Stabilizer Model I-2000 <strong>Vibration</strong> Isolators, is at the heart of the system. This technology<br />
is renowned for compact size, faster settling times, superior high-center-of-mass stability,<br />
lower natural frequency, and a patented, self-centering piston mechanism.<br />
Four isolator modules recessed into the bottom of the platform achieve top-notch table top<br />
vibration isolation. Each contains a pneumatic, flexible rolling diaphragm that supports the<br />
load, thereby decoupling vibrations from the isolated platform. If the platform is disturbed,<br />
the modules automatically relevel the platform using compressed air.<br />
No more bulky canisters to impede instrument access, restrict arm positioning or crowd<br />
workspaces. Newport’s hybrid-chamber design allows all vibration modules to be<br />
completely hidden <strong>with</strong>in the platform.<br />
The BenchTop also minimizes fatigue. That’s because its low profile design adds only<br />
about two inches of height to your support surface. Add optional padded armrests - and<br />
you can work for hours <strong>with</strong> unparalleled ease.<br />

either plastic laminate or stainless steel tops, the<br />
BenchTop is ideal for providing vibration isolation<br />
in applications involving time lapse photography,<br />
videomicroscopy, probing and manipulation of cells<br />
under high magnification.<br />
