Passive Anti-vibration Platform
Superior Mechanical Design
Overview
Anti-vibration technology works in horizontal direction by utilising ball bearings sandwiched between precision raceways, forming the plane of isolation.
When the ball bearings displace and restore into their positions in raceways, they act like nonlinear springs that cut off the transmission of vibrations.
The oscillating motion of the ball bearings have no "natural" frequency, therefore the resonance between the two halves of the isolation plane become physically impossible.
As a result, the isolator filters out a broad band of input vibration frequencies and insures a constant level of vibration transmission reduction. Vertical vibration isolation is handled by the proprietary, nonlinear spring mechanism with near zero tangential stiffness for vibrations.
The natural frequency of the spring remains relatively low and constant across a large range of spring compression, effectively isolating the vertical vibrations.
Isolators Featured in VIP Vibration Isolation Platform
Microscope platforms are compact, effective and easy-to-use platforms that significantly reduces vibrations from disturbing sensitive instruments such as microscopes, inspection or analysis equipment.
Patented Mechanical Isolation
Mechanical isolators using technology that is maintenance-free and user configurable.
Featuring great robustness for tough environment, quicker settling time than pneumatic isolators and solid performance for vibration isolation, the isolators are very popular among microscopy, precision measurement and inspection, and other sensitive applications.
Vibration Guidelines
Guidelines for levels are published by ASHRAE (American Society of Heating Refrigeration and Air Conditioning Engineers)
There are lots of vibration curves applicable to a lab and procedures (what we use to measure the parameters)
This from chapter 48 of the handbook gives some guidelines
| Equipment up to 40x microscope 8 - 80 Hz curve 0.203mm/s |
| Bench scopes up to 100x 8 - 80 Hz curve 0.102mm/s |
| Micro surgery (ICSI) 8 - 80 Hz curve 0.051mm/s |
As you can imagine the sources of vibration is high in a laboratory.
The source of vibration can be caused in XY and Z planes.
Typically it is Z (vertical) that we see in background vibration for the main room such as the laboratory built on a concrete slab.
We know that centre of concrete slabs resonate so the edge of the room is better but will still cause vibration. Doors opening - especially on a partition wall (banging doors and soft closer's) in corridors can translate to vibration onto the ICSI bench in either the x or Y planes if not isolated.
(Do not attach ICSI workstations to walls)
If your laboratory room for ICSI is near a corridor or the ICSI has to be in a fixed bench set up consider the TS150 AV platform, if you have low vibration the VIBe passive system will work.
IVFsynergy would never recommend to have no isolation for ICSI / PGD. Choose Passive or Active systems depending on your background risk. Please contact us for more support.
Passive damping systems work well at relatively high frequencies (> 50Hz) but fail at low frequencies where building vibrations occur. Passive systems have their resonance frequency there and amplify the vibrations instead of damping it in that region.
