1 Safety instructions and operational limitations

The antivibration pads are used to prevent the effects of external shaking or vibrations in the
microscopy area in the lab.

The antivibration pads are positioned under the respective feet of the microscope.

Risk of injury!

The microscope must be lifted and placed on the antivibration pads. Here there is a risk of the
fingers becoming caught! Observe the instructions for the lifting of heavy loads!

The antivibration pads may only be loaded with the prescribed weight. Overloading can cause
permanent damage to the antivibration pads!
The antivibration pad has no effect when the load is too light.

Incorrect adjustment of the antivibration pads to the weight of the microscope structure
(microscope and the components attached to it) can eliminate or reduce the damping effect
significantly.

Microscopes can be heavy.

Safety instructions and operational limitations

2 Functional principle

The antivibration pads should isolate microscope workplaces from external oscillations.
The antivibration pads are positioned under the respective feet of the microscope.
For an example see Figure 1.

Functional principle

Figure 1: View of a microscope with antivibration pads, with load of two microscope feet (front)
and one each (rear).

The choice of the antivibration pads depends upon the weight of the microscope and its
components. Of decisive importance here is the mass affecting the respective microscope foot.
The necessary antivibration pads can be chosen from 5 categories.

Weight range [kg] Weight range [US lb]

Antivibration pad from to from to

Antivibration Pad XS 4.5 6.0 9.9 13.2

Antivibration Pad S 6.0 8.0 13.2 17.6

Antivibration Pad M 8.0 10.0 17.6 22.0

Antivibration Pad L 10.0 12.5 22.0 27.6

Antivibration Pad XL 12.5 16.5 27.6 36.4

A rule of thumb for selecting the antivibration pads cannot be provided, as the range of variation
of the microscope, its attachments and accessories, as well as of the most varied range of
micromanipulators is extremely broad.

2 Functional principle

The antivibration pads consist of two half-shells connected inside by an insulating material.
See Figure 2.

Figure 2: Antivibration pad

The insulation material absorbs incoming external vibrations, footfalls and building vibrations
that affect the microscope setup.

The insulation material functions best when it is slightly compressed. This is apparent with a
smaller gap between the two half shells.

This is visible in the gap between the two half shells. This gap also serves to control whether the
antivibration pad has been positioned correctly. When correctly positioned, the edges of the
gap must always be parallel to one another. The insulation function is eliminated when the two
half shells come into contact at any point. On the other hand, the damping function is also
prevented by an inadequate sinking depth (in the case of an antivibration pad that is too strong).

The underside of the antivibration pad has a grip mat. The identification plate including weight
class entry is found in the middle of the mat.

3 Operation and work techniques

The antivibration pads are positioned under the respective microscope foot.

Selection and positioning of the microscope antivibration pad:

– Determine the weight of the microscope structure individually for all microscope feet.

3

– Select the antivibration pads on the basis of the distance of the front or rear microscope

feet and the respective weight.
Example from Figure 1:
Front: two feet with a total weight of approx. 9 kg: Use of a "M" antivibration pad.
Rear: Approx. 11 kg per foot: Use of a "L" antivibration pad for each foot:

– Lift the microscope in accordance with the manufacturer instructions for the microscope

and the guidelines for the lifting of heavy loads.

– Position the respective antivibration pad centered below the foot of the microscope and

carefully lower the microscope.

– Check: the antivibration pad should be pressed approx. 1.5 – 2 mm together. The gap of the

antivibration pad must be the same all around. The two shells of the antivibration pad must
lie on top of one another and may not be pushed to the side.

4 Maintenance, cleaning and sterilization

4.1 Cleaning

It must be ensured that no fluids find their way into the interior of the antivibration pad.
Wipe off painted parts and surfaces with a cloth and mild cleaning agent then rub with a dry
cloth.

Warning:

Do not use corrosives, solvents or grinding cleaning or polishing agents.

4.2 Disinfection

The antivibration pad should be cleaned prior to disinfection.

Autoclaving or disinfection with radioactive irradiation or gases is not permitted!

All surfaces of the antivibration pad are to be subjected to a wiping disinfection with alcohol
(ethanol, isopropanol) or alcohol-based disinfection agent.

Spray disinfection is to be avoided, as this can result in disinfection media finding its way into
the interior of the antivibration pad. The damping material can thereby be damaged.

The disinfection method applied must satisfy all applicable legal regulations and guidelines for
disinfection.

4.3 Decontamination prior to shipping

If the device is to be inspected or repaired by the service partners of the Eppendorf AG, it must
be free of hazardous substances and clean!

A decontamination certificate must accompany the antivibration pad.

A "Decontamination certificate for the return of goods" form and general instructions for the
decontamination are available at our www.eppendorf.com homepage.

5 Troubleshooting

Error description Cause Solution

No or too little damping Antivibration pad is too soft.

5

No or too little damping after
a longer period of time

No or too little damping Antivibration pad is too strong.

Troubleshooting

No or too little damping Antivibration pad is not

Both shells come in
contact with one another.

Antivibration pad is too soft.
The damping material is com­pressed too much over time by a
too heavy load. The initial sinking
depth exceeded 2 mm.

The antivibration pad is not
pressed together adequately
(1.5 – 2 mm)

positioned correctly under the
microscope foot. Shells come in
contact with one another.

Use stronger antivibration
pad.

Use stronger antivibration
pad.

Use weaker antivibration
pad

Center the antivibration
pad under the microscope
foot (see chapter 3).
