11.4.1
Maximum Permissible Rotation Speed Setpoints
INFORMATION
The following information is based on an ideal tray load of 14 kg
made up of standard Erlenmeyer flasks with no baffles, and a fill
level of 30 %. For information on the optimum load weight de-
pending on the speed, see chapter 6.2.6 “Tips & Tricks for Load-
ing the Tray”, page 58.
The following guidelines for the maximum rotation speeds are speci-
fied to avoid damage. As such, they must be observed, though other
restrictions (e.g. tray with Sticky Stuff adhesive matting) must also be
taken into account.
Due to the lever effect, the maximum permissible speeds for the top
device units in stacks are lower than for single units.

All this information is intended solely as a guideline (not guaranteed).
Depending on the load, higher rotation speeds are possible; in this
case, the rotation speed should be increased slowly. In such cases,
the user is responsible for determining the maximum possible rota-
tion speed based on the vibrations and the vessel holders (the clamps
may need to be secured) and communicating them. If vibrations oc-
cur, reduce the rotation speed until the device runs smoothly. Alter-
natively, increase or reduce the load until the device runs smoothly.
