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 precision weighing scales.The platform makes an attractive base for your microscope or other precision instruments.Applications:MicroscopesPrecision weighing scalesLasersElectro-optic systemsMicro positionersPrecision measuring instruments such as micro hardness and laser dimensional measurement instruments.Silicon wafer inspection stationsTurntable isolationBenefits:Simple and effective vibration isolation.Reduced eye fatigue compared to no vibration isolation.Compared to an air vibration isolation table, the VGI Granite Isolator is significantly less expensive and does not require an air supply.Installation and handling is easier than an air vibration isolation table which can be quite heavy.It is reliable because the VGI Isolator consists of only a granite mass on compliant supports. No air bladders, seals, or air valves that can run into problems over extended periods of time. Long-term reliability is assured because there is nothing to adjust or maintain.Cleanroom compatible. There are no moving parts, no air valves that have been known to send bursts of particle-laden air into the cleanroom. Granite is very abrasion resistant and an ideal cleanroom material.Much smaller and lower profile than air tables or benchtop air platforms.If the center of gravity of the microscope is too high, benchtop air isolation platforms can run into problems such as tilting too much or bottoming out on the isolators on one side. This problem is often solved by making the air isolation platform much larger than the microscope base. Unfortunately, this wastes useful table space. The VGI Granite Isolator does not need to be significantly larger than the microscope base.The VGI-M is a vibration granite isolator that is 16" x 21" that has a maximum recommended load of 140lbs.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 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. 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 are looking for, and they look very nice under your precision microscopes, balances and other precision instruments.
