We've found these granite vibration isolation platforms to be excellent general purpose anti-vibration pads. There are two available:
VGI-MM 21"x16" for up to 70 lbs weight
VGI-M 21"x16" for up to 140 lbs weight
Uses High Grade Silicone Gel for the vibration isolators. Placed at the four corners of the granite, the silicone gel supports are highly compliant and have a high level of internal damping.
Simple and low cost vibration control.
No air supply required as with an air-based isolation table.
Used for over 10 years on high performance microscopes and precision weighing scales.
The platform makes an attractive base for your microscope or other precision instruments.
The Granite Isolator consists of only three different parts. The granite top is designed to be about the size of the microscope or other precision instrument. Special, high grade silicone gel isolators are underneath the four corners of the granite, and an ABS plastic baseplate is attached under the silicone gel isolators so that the platform can be easily slipped under the microscope, electronic balance, or other precision instruments.
The silicone gel supports of our platforms are the key as they are very compliant with high internal damping, they isolate micro-vibrations as well as larger motions, and have long life ( we have many installations of greater than 8 years). In addition, the silicone gel supports are easy to use as they require no adjustment, no air supply, accommodate a wide range of loading with excellent performance, and are ideal for use in cleanrooms. The granite tops give us the weight we are looking for, and they look very nice under your precision microscopes, balances and other precision instruments.
