General Description
The SCF3 is a compact microcentrifuge for the centrifugation of microfuge tubes ranging from 0.2ml to 2.0ml or
2 x 8 PCR tube strips at speeds of up to 15000rpm. The unit is supplied with a pre-installed 12 x 0.2/2ml rotor
and a 2 x 8 0.2ml strip rotor can be ordered. The rotors are easily installed without the use of tools. Centrifugation
speed can be displayed as either rpm or rcf and the timer can be set for run times of between 30 seconds to 999
minutes and innite mode. In addition, a short spin button spins the rotor to the preset rpm then promptly
decelerates. For safety, the door of the SCF3 remains locked while the rotor is in motion.
Important Safety Advice
Users should be aware of the following safety advice:
v SHOCK HAZARDS OR UNSAFE PRACTICES ARE DANGEROUS as they can cause severe personal injury, re
or death.
v DO NOT use combustible substances near hot objects.
v DO NOT use the equipment in hazardous atmospheres.
v DO NOT operate or handle any part of the product with wet hands or use on surfaces that may become ooded.
v NEVER move the product while still connected to the power supply.
v HIGH TEMPERATURES ARE DANGEROUS as they can cause serious burns to operators and ignite combustible
material.
v USE CARE AND WEAR PROTECTIVE GLOVES TO PROTECT HANDS.
v NEVER lift or carry the instrument during operation.
v DO NOT position the unit so that it is difcult to disconnect from the mains supply using the mains plug.
v The mains outlet socket used should be located close to the equipment and readily identiable and accessible
to users.
v DO NOT leave equipment switched on and it is not recommended to leave any heating apparatus unattended
during operation.
v The unit should be carried using both hands.

Electrical Requirements
THIS INSTRUMENT MUST BE GROUNDED
Before connection please ensure that the line supply corresponds to the power requirements below:
Power: 72W Supply requirements: 100 - 230 VAC, 50-60Hz
The unit is provided with a power adaptor and three power cables consisting of a UK 3-pin and a “Schuko” 2-pin
plug for 230 V installations and a NEMA 5-15 plug for 120 V installations.
Choose the power cable appropriate for your electrical installation and discard the other. Should neither power cable
be suitable for connecting to the power supply, replace the plug with a suitable alternative..
THIS OPERATION SHOULD ONLY BE UNDERTAKEN BY A QUALIFIED ELECTRICIAN.
3
NOTE: Refer to the equipment rating plate to ensure that the plug and fusing are suitable for the voltage and
wattage stated. The wires in the mains cable are as follows:
230V 120V
BROWN - HOT/LIVE BLACK - HOT/LIVE
BLUE - NEUTRAL WHITE - NEUTRAL
GREEN/YELLOW – EARTH GREEN - EARTH
The appropriate power cable and power adaptor combination should be connected to the instrument BEFORE
connection to the mains supply. Should the mains lead require replacement, a cable of 1.25mm² (AWG16) of
harmonised code H05VV-F connected to an IEC320 plug should be used.
IF IN DOUBT CONSULT A QUALIFIED ELECTRICIAN

Connecting the power adaptor
1. Ensure the power switch is OFF before connecting the power adaptor.
2. Connect the appropriate power cable to the power adaptor.
3. Connect the power adaptor to the centrifuge. Ensure you align the notch on the power adaptor with the rib
on the centrifuge. If they are aligned correctly the plug will go in easily. IF THESE ARE NOT ALIGNED YOU
WILL NOT BE ABLE TO CONNECT THE POWER, DO NOT FORCE TOGETHER!
4. Once the plug is in position turn the locking ring clockwise to secure the connection.
Loading the rotor
Always check the rotor is tted correctly, rmly tightened and balanced before centrifugation. Below are examples
of correctly and incorrectly balanced rotors.
The samples in the tubes should be of equal volume and must exceed the maximum capacity of 12 x 1.5/2ml. Do
not use with liquid with a density higher than 1.2g/ml for full load operation.
Prior to centrifugation check the tubes for damage and they are loaded correctly. Damaged or incorrectly loaded
tubes can cause vibration or imbalance which can lead to serious damage to the unit.
If the tubes are not loaded symmetrically then the imbalance detector will cut off the running centrifuge for device
& user safety. This will stop the centrifuge and “Err 55” will be seen indicating tubes are not loaded symmetrically.
To resume operation, load tubes symmetrically & restart the centrifuge.
