Safety Advice Before Use
❖ The unit should be carried using both hands
with fingers under each side frame.
❖ Do not stop rotation by hand.
❖ In the case of mains interruption, a fault or
mechanical failure, the unit will continue to
operate on removal of fault.
❖ Never move or carry the unit when in use or
connected to the mains electricity supply.
❖ Ensure that the rotator disc is evenly balanced
with tubes.
❖ Mechanical energy can lead to breakage of
glass vessels. Use with care.
❖ Ensure that there is sufficient free space
around the rotator so that it does not come
into contact with anything during use.
Operation
(see fig 1 & 2)
Unpack the Rotator and the accessory tube
holder(s). Assemble using the instructions
provided with the tube holder.
N.B. Keep these instructions in a safe place.
Position the apparatus on a firm level surface
ensuring there is sufficient room for the disc to
rotate.
SB2 Fixed speed version
Loosen the righthand side wheel by turning anti-
clockwise and position the holder to the
optimum angle. Tighten the hand wheel by
turning clockwise. Load the tube holder ensuring
that it is evenly balanced.
Switch the unit ON using the mains On / Off
switch (see fig 1). The unit will rotate at a fixed
speed of 20rpm. Once mixing is complete switch
the unit OFF using the same switch and unload
the tubes.
SB3 Variable speed version
Loosen the righthand side wheel by turning anti-
clockwise and position the holder to the
optimum angle. Tighten the hand wheel by
turning clockwise.
Load the tube holder ensuring that it is evenly
balanced.
Switch the unit ON by pressing the control knob
in (see fig 2). The red display will show present
2
set speed (red dot in the display shows RPM is
selected). This can be adjusted by turning the
control knob. Once the correct speed is displayed
press the start / stop button to begin rotating.
Rotation can be halted at any time by pressing
the start / stop button.
Using the timer (SB3 only)
In order to use the timer, halt rotation and press
the mode button. The red dot on the display
moves over to MINS. Select the desired count
down time using the control knob. When the
display shows the correct time in minutes, press
the start / stop button to begin rotation.
During operation, rotation can be paused at any
time by pressing the start / stop button. If this
button is pressed again, rotation will start again
and the timer will continue to count down.
When the timer reaches zero, rotation will be
automatically halted and an audible alert will
sound. The display settings will revert back to the
last values saved in the memory (see saving speed
/ time values section below).
To disable the timer and revert to continuous
rotation, select - - - in the display in timer
mode.
To switch the Rotator OFF completely, press the
control knob in.
Saving speed / time values
In order to save a commonly used speed / time
value, switch the unit ON by pressing the control
knob in (see fig 2) and select both a speed value
(2 to 40rpm) and a time value (either 1 to 999
minutes, or continuous - - -) using the instruction
given above. Then switch the unit OFF by
pressing in the control knob. Wait 5 seconds and
switch the unit back ON by pressing the control
knob in. The inputted values are now saved in
the memory. They can be altered at any time by
following the same procedure.
