The VGI 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.
VGI-M Info:
Vibration Granite Isolator (16" x 21") Maximum recommended load is 140lbs; utilized by MC, IM, TC, MT6000 series
Features:
• 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 precission weighing scales.
• The platform makes an attractive base for your microscope or other precision instruments.

Although the VGI Granite Isolator platform does not isolate from vibration as well as an air table, it is well suited for the 200x to 1000x objective magnification range. Higher magnifications should continue to use air tables.
Note however that air tables can also be used with the VGI Granite Isolator platform for better vibration control than obtained with air isolators alone.
Granite platforms with unique silicone gel isolators offer new vibration damping solutions for noise sensitive industrial, laboratory, cleanroom, and inspection areas. Typical examples include:
