Hamilton CleanBench Anti-vibration Table

Hamilton CleanBench Anti-vibration Table

Manufactured by TMC (Technical Manufacturing Coproration), the CleanBench™ vibration isolation lab table is ideal for IVF applications. CleanBench incorporates TMC's unique Gimbal Piston™ Vibration Isolators and a tabletop with enhanced performance and features.

Gimbal Piston™ Vibration Isolators: The CleanBench table incorporates TMC’s Gimbal Piston Air Isolators as a standard feature. The Gimbal Piston has consistently shown to out-perform other air isolators in side-by-side testing. It offers outstanding low frequency vibration isolation in all axes and maintains its performance specifications even when subjected to extremely low input levels of excitation. Proprietary damping techniques allow the Gimbal Piston to stabilize relatively top-heavy payloads and quickly dissipate disturbances of the isolated table top.

The Gimbal Piston Air Isolator provides outstanding isolation in all directions for even the lowest input levels. It is lightly damped and highly responsive to typical, low-amplitude ambient floor vibrations, yet achieves very high damping for gross transient disturbances, such as sudden load changes or bumping the top plate. The result is that Gimbal Piston Isolators provide superior isolation yet will virtually eliminate any gross disturbance within a few seconds. It can also stabilize isolated systems with relatively high centers of gravity without compromising isolation.

Application Note: The Exploratorium, San Francisco uses the CleanBench Table with Gimbal Piston™ Vibration Isolation System as part of their museum experience. The exhibit features a time-lapse video, taken under a microscope, of a transparent zebrafish maturing from a single cell to a fully developed hatching egg. The images were captured using a Zeiss Axiocam 200M inverted optical microscope and digital camera. Essential to the experiment was that the image remain completely motionless for the entire 61 hours of the embryo’s development.

Features

• Greater stability, especially for small size tables. The low profile, high density tops lower the overall floating center-of-mass ensuring inherently stability, even for relatively top-heavy payloads.
• Ergonomics optimized for the seated user by minimizing the thickness of the table-top. Other designs either offer 4" (100 mm) thick tops which awkwardly separate knees and elbows orsacrifice essential mass by offering a 2" (50mm) thick honeycomb top which does not have adequate mass for effective vibration isolation, especially for smaller table sizes.
• The Patented Gimbal Piston™ Isolator has been proven by independent tests to consistently outperform the competition. It achieves both horizontal and vertical isolation down to very low input levels.
• Thin-Wall Rolling Diaphragms — An integral part of the Gimbal Piston, the thin-wall, dacron-reinforced, rolling diaphragm air seals are only 0.020 in. (0.5 mm) thick and extremely flexible. They do not stiffen the spring as thicker rubber diaphragms do.
• Aluminum Height Control Valves — All systems are equipped with aluminum height control valves which are finger adjustable (no need for tools). The standard model maintains height to ± 0.050 in. (± 1 mm); the precision model, to ± 0.005 in. (± 0.1 mm).
• Internal Piston Travel Restraint — Unique in the industry, TMC provides tamper-proof, built-in piston travel restraints. The restraints are completely independent of the table valves and have been ram-tested at forces above those produced by the pistons operating at full pressure. They cannot be decoupled accidentally and do not interfere with setting up and using the table, but simply protect against overtravel without the use of external bars that create hazardous pinch points. Heavy loads, including the top plate, can be safely removed from a table in full operation.
• Built-in Leveling Feet — Table legs include built-in fine-thread 3 in. (75 mm) diameter screw jack levelers with 1/2 in. (13 mm) travel, provision for external adjustment, and a handy adjustment wrench. The base is a solid, slightly domed shape to assure solid contact.
• Multiple Sizes - Available in various dimensions of 24" x 36" up to 36" x 60"
• Accessories include arm rests, retractable casters and shelves.
