Features

Stabilizer™ Vibration Isolation Technology

CM-225 Series Pneumatic isolators used in BT Series, featuring Stabilizer™ vibration isolation technology adapted from Newport's acclaimed Stabilizer Model S-2000 Vibration Isolators, are at the heart of the system. This technology is renowned for compact size, faster settling times, superior high-center-of-mass stability, lower natural frequency, and a patented, self-centering piston mechanism. It offers the largest compliance volume and, therefore, the best vertical isolation of any compact isolators.

Integrated Leveling Valves for Improved Repositioning Accuracy

Four isolator modules are recessed into the bottom of the platform, achieving top-notch table top vibration isolation. Each isolator module contains a pneumatic, flexible rolling diaphragm that supports the load, thereby decoupling vibrations from the isolated platform. If the platform is disturbed, the modules automatically relevel the platform using compressed air.

Ergonomic Mechanical Design

No more bulky canisters to impede instrument access, restrict arm positioning or crowd workspaces. BT’s hybrid-chamber design allows all vibration modules to be completely hidden within the platform. The BenchTop also minimizes fatigue. That’s because its low profile design adds only about two inches of height to your support surface.

Custom Working Surfaces

BenchTop Series is ideal for providing vibration isolation in applications involving time-lapse photography, video microscopy, probing, and manipulation of cells under high magnification. Standard catalog platforms come with 3 working surface options: a white plastic laminated surface, and stainless-steel tops with or without mounting holes. Please refer to the table below for the benefits of different working surface options.

Cleanroom versions (BTC models) are also available as standard catalog products for all three working surface options.
