TS150 Active Anti Vibration Platform
This compact state-of-the-art dynamic vibration isolation table achieves better isolation than most other comparable vibration damping systems. Ready-to-use on a plug-and-switch basis, the TS150 now has been setting the standards for an excellent performing and easy-to-handle vibration isolation solution.
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 to work with
| 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 not recommend to have no isolation for ICSI / PGD. Choose Passive or Active systems depending on your background risk. Please contact us for more support.
Active vibration isolation systems employ inertial velocity in a feedback loop. A signal proportional to inertial velocity is very similar to a viscous damping force, but with the very important difference that the damping is relative to an inertial plane. So in contrast to the passive system, by increasing the damping as in curve [C] and [D], the system becomes 'glued' to the inertial plane which by definition means the system is isolated from the environment.
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.
