Power
SF1
230V, 50Hz
50W
All models are supplied with two mains leads
fitted with IEC plugs for connection to the
instrument. One has a U.K. 3 pin plug and the
other has a 2 pin “Shuko” plug for connection
to the mains. Choose the lead appropriate for
your electrical installation and discard the other.
Should neither lead be suitable, take the lead
with the U.K. plug and replace the plug with a
suitable alternative. This involves cutting off the
moulded plug, preparing the cable and
connecting to the re-wireable plug in accordance
with its instructions.
THIS OPERATION SHOULD ONLY BE
UNDERTAKEN BY A QUALIFIED ELECTRICIAN
NOTE:
Refer to the equipment’s rating plate to
ensure that the plug and fusing are suitable for
the voltage and wattage stated.
The wires in the mains cable are coloured as
follows:
BROWN
- LIVE
BLUE
- NEUTRAL
GREEN/YELLOW - EARTH
The instruments are fitted with an IEC socket at
the rear of the instrument for connection of the
mains lead. The appropriate mains lead should
be connected BEFORE connection to the mains
supply.
Should the mains lead need replacement, a cable
of 1mm
2
of harmonised code H05W-F connected
to an IEC320 plug should be used.
IF IN DOUBT CONSULT A QUALIFIED
ELECTRICIAN
Safety Advice Before Use
The unit should be carried with both hands,
with fingers under each side of the frame.
Never move or carry the unit while it is in use
or connected to the mains supply.
There is a danger of liquid spillage and
splashing if containers are over-filled and
shaken at high speed. Always build the
shaking speed up slowly and never shake
more rapidly than necessary.
Ensure the load is balanced.
General Description
The SF1 flask shaker comprises two side arms
each with four clamps capable of holding bottles
or flasks up to 500ml capacity. The vigorous
mixing action simulates hand shaking and this
motion is controllable between 80 and 800
oscillations per minute. The speed is controlled
by a soft start feedback controller to avoid
splashing on start up and give constant speed,
irrespective of load.
There is a built-in analogue timer that can be set
from 10 to 60 minutes, which automatically
turns the unit off once it has counted down.
There is also a manual control position for
continuous operation.
Accessory side arms are available to increase the
capacity to twelve bottles or flasks.
