General Operating Instructions

Insert a slide into each of the cassettes on the rotor. Note: Always run 2 slides at once. Use a blank slide
as a balance if only one slide needs to be dried. To begin a run, simply close the lid of the centrifuge. No
other controls are required. Typically a 10 second spin is required to completely dry the microarray slides.
To stop rotation, press down on the lid release tab on the front of the unit or put the switch on the side to the
"off" position. Pressing the tab will release the lid lock and the rotor will slow gradually to a complete stop.
When the rotor has come to a complete stop, open the lid and remove the slides. The cassettes can be
removed from the rotor for easy disposal of the liquid that collects at the bottom of the cassettes.
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. Always run 2 slides for
proper rotor balance.

Maintenance

Before using any cleaning or decontamination methods except those recommended by the
manufacturer, check with the manufacturer that the proposed method will not damage the
equipment.
To clean the centrifuge: use a damp cloth and mild, noncorrosive detergent (pH<8). After
cleaning, ensure all parts are dried thoroughly before attempting to operate the unit. Do not
immerse the centrifuge in liquid or pour liquids over it.
The recommended cleaning method for the cassettes is with a mild non-alkaline detergent. For
decontamination of the internal part of the cassettes the manufacturer recommends using
Ultrasonic Cleaning Units (it is very effective for destroying DNA – autoclaving doesn't effectively
destroy DNA).
The cassettes are not resistant to alkaline detergents, or acids

Questions and Service

Should you have a question about the centrifuge or require service for the unit, please contact your
VWR International representative. Do not send in a unit for service without first calling to obtain a
repair authorization number and a decontamination form. Should the centrifuge require service,
be sure to decontaminate it and enclose the decontamination form. The unit should be properly
packed to avoid damage. Any damage resulting from improper packaging shall be the
responsibility of the user.
