to avoid your hands coming into contact with hot water or the heating element.

When working with glass tubes, flasks, bottles, breakable or other brittle or fragile articles it is important
to use an appropriate retaining rack or fixture that ensures individual vessels are supported
independently and cannot come into contact with one another.
For example, if using glass test tubes, each tube should be retained in it’s own division of a test tube
rack, and the rack itself should be wide enough to be retained by the base of the oscillating cradle
without sliding around during oscillation. A powder coated stainless steel test tube rack is
recommended for retaining test tubes.
No vessel should be allowed to come into contact with any other vessel during high speed oscillation in
order to prevent breakage and a potentially hazardous situation from being created.
ALWAYS use appropriate tools (such as silicon insulated tongs) to load and unload items from the
water to avoid your hands coming into contact with sharp, broken or contaminated vessels.
-
Turn power Off to the oscillating cradle by setting the Oscillation On/Off mains power switch (element
6 in Figure 1) up to the setting marked with a circle.
-
When loading, use appropriate tools (such as silicon insulated tongs) to place the required rack,
container or accessory onto the oscillating platform. Ensure the item is adequately retained by the 2
retaining walls on the bottom of the cradle. If the item is too small to be adequately retained, it should
be loaded into another suitable rack or tray which will be adequately retained by the retaining walls.
-
When unloading, use appropriate tools (such as silicon insulated tongs) to slowly remove the items
and place them onto a water-proof and heat-proof surface.
-
Continue to load or unload your containers, racks or accessories until complete.

Be careful when working with hot items removed from the water bath as burns or scalding may occur if
contact occurs.
Always wear eye protection when loading or unloading items from a hot water bath.
Do not use explosive or volatile containers with this water bath.
Ensure all containers remain tightly sealed at all times whilst loading and unloading the water bath.
Only use containers suitable for the water temperature selected.

Always turn the Oscillation speed control knob (element 2 in Figure 1) down to setting 0 before starting
the oscillating cradle. This will assist in preventing any splashing or unexpected behavior once the
cradle starts to move.
-
Turn the Oscillation speed control knob (element 2 in Figure 1) down to setting 0.
-
Turn power On to the oscillating cradle by setting the Oscillation On/Off mains power switch (element
6 in Figure 1) down to the setting marked with a vertical line. The Oscillation On/Off mains power
switch (element 6 in Figure 1) will light up red to indicate the speed control is now active.
-
Slowly turn the Oscillation speed control knob (element 2 in Figure 1) clockwise up towards the
required oscillation speed, the cradle will begin to move.
-
Continue to increase the speed until the desired oscillating speed is reached.
-
Note : In cases where the required oscillation speed is very slow, it may be necessary to increase the
oscillation speed to slightly more than the required speed, and then reduce the speed back to the
