Secure vessels on shaker plate

Adaptors for Erlenmeyer flasks, separating funnels and an adaptor with clamping rollers
for universal use are available.
➜ To secure vessels on shaker plate, use optional adaptors (see chapter „Spare parts
and accessories" and chapter „Assembly").
➜ At low shaking speed, low-profile vessels like petri dishes may be placed directly on
the non-skid rubber plate.
A single flask should be arranged in the middle of the shaker plate.
Several flasks should be distributed equally on the plate.

Shaking mode


Warning:
Risk of injury!
Returning power after a power cut off will restart shaking mode. There
is a risk of injury in the vicinity of moving parts of device.
Before working with the device or in the vicinity ensure all controls are
switched to "0" or "OFF" mode, when device is not moving.
Caution:
Risk of breakage and spillage
If the vessels are not attached securely they may fall out and spill the
sample.
Prior to switching the unit on ensure that all vessels are securely
fastened.
If working with separatory funnels make sure that the outlet pipes of
your separatory funnels are clear of other items on your lab bench.
Warning:
Risk of poisoning
Open vessels and too high vibration frequencies may result in samples
splashing.
Close all vessels tight especially if sample is dangerous or toxic.
Adjust vibration frequency step by step until you have reached the
required rpm settings..
Wear safety glasses and especially with dangerous and toxic samples
appropriate protective clothing.

Operation
Warning:
Risk of injury!
High speeds in combination with high loads and/or a tall assembly may
lead to an unstable device. As result the device may start moving and
slide off the table top.
When working with with high loads and/or a tall assembly, increase the
speed with care and watch for the devices stability. Ensure the device
is installed in such a way as it can not collide with the surrounding
environment or slip off its work surface.
At high loads (load-bearing capacity of shaker plate) and high
frequency of shaking, always make reference to load graph as appli-
cable for your item (see chapter „Technical data", section "Performance
range, permissable load").
When using shakers inside conditioning cabinets, make reference to
ambient conditions (see chapter „Safety, Operating company's obliga-
tions", section "Installation site").
