Labnet Spectrafuge Mini Laboratory Centrifuge - Manual (Page 2)

General Information:
The Spectrafuge Mini Centrifuge is supplied with two rotors, one for microtubes and one
for 0.2ml PCR strip tubes. The 6 x 1.5ml rotor is designed to centrifuge up to six
individual 1.5ml plastic microcentrifuge tubes. It will also accept 0.5ml and 0.4ml tubes
with the adapters supplied with the unit. Adapters are available separately for 0.2ml
tubes. The strip tube rotor is designed to centrifuge two 8 x 0.2ml strip tubes. It will also
accept up to 16 individual 0.2ml tubes. Both rotors are designed for applications
requiring relatively low g-forces, such as microfiltration, cell separation and quick spin
downs from the walls of tubes. Please read this manual thoroughly before attempting to
operate the centrifuge.
If the equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Warranty:
The centrifuge and rotor are covered by a one year warranty. This warranty covers the
centrifuge and rotor. This warranty is void in the event of incorrect operation, use of
nonstandard spare parts or accessories and unauthorized modification of the rotor or
centrifuge. The rotor warranty does not cover normal wear and tear or damage and/or
weakening caused by radioactive contamination, cleaning agents, or over tightening of
the allen screw. Fuses are not covered by the warranty.
Exchanging Rotors:
The centrifuge is supplied with two interchangeable rotors. The rotors are easily
exchanged using the allen wrench provided. Locate the set screw on the rotor shaft
below the rotor head. Using the wrench, loosen the set screw and pull up on the rotor to
remove. Place the other rotor into position on the motor shaft. Take care not to press the
rotor down so far as to compress the rubber collar at the base of the shaft. Tighten the
screw using the allen wrench until finger tight. Do not over tighten as this will cause
damage to the rotor and the motor shaft.
Installation:
Place the centrifuge on a level, clean surface, position the centrifuge near an accessible
power outlet so that the cord and outlet are within easy reach of the operator.
Operation:
Before operating the centrifuge, be sure that the power switch is in the “on” position. To
begin a run, simply close the lid of the centrifuge. No other controls are required. To stop
rotation, press down on the lid release tab on the front of the unit. This will release the lid
lock and the rotor will slow gradually to a complete stop. Caution: Do not attempt to open
the lid or remove samples until the unit has come to a complete stop. After the rotor has
stopped, the lid may be opened by grabbing it with the thumb on the front and fingers on
the back then lifting the lid back on the hinge. Safe operation of the centrifuge requires
that the rotor be loaded in a balanced fashion. Failure to load the rotor properly presents
a hazardous condition and may damage the centrifuge. Individual tubes, strip tubes
and/or adapters must always be loaded symmetrically to ensure proper balance. Never
run the centrifuge with only one strip tube in place.
