Support, Vibration and Movement Requirements

At a minimum, the supporting structure usually consists of a base cabinet and
chemically resistant work surface.

XPert and XVS:

• When setting up a chemical station not used for weighing powders, a

mobile stand or cart is allowable.

The ability for analytical balances to accommodate vibration varies with type
and brand. More advanced balances have improved reliability, however in
the preparation of a balance enclosure site, please consider the following:

• Avoid tubular stands or carts that have the potential of moving when

touched.

• Work surfaces should be of a thick rigid material that remains stable

when buttons are pressed. An epoxy benchtop or accessory work surface
is a minimum requirement.

• A bench that is rigidly mounted to the floor or fixed to the wall, but not

both, may be appropriate.

• The corners of a building typically have less vibration than the center.

• The bench with the balance enclosure should not contain any vibration-

producing equipment, such as shakers or pumps.

• Marble, granite or epoxy balance tables are generally recommended by

the manufacturers of analytical and microbalances. (See the installation
instructions in Chapter 3).

• Marble slabs within the balance enclosure with dampening pads are also

an effective low cost means of controlling vibration.

Temperature Variation Requirements

XPert:

The extent the balance readings are influenced by temperature variations is a
function of the balance design. Most manufacturers would suggest that a
temperature drift of 1-2°C is generally tolerable. Only validation through
your Operational Qualification protocol can define what is acceptable. To
minimize the potential for temperature variations:
