Care and Preventative Maintenance:
With proper care and maintenance your centrifuge will provide years of laboratory service. For
proper care, the following steps should be taken:
1. Provide Adequate Ventilation: For cooling purposes, the centrifuge draws in ambient air
through the air intake cover on the top of the lid and exhausts this air in the rear of the base.
The centrifuge should be placed on a hard smooth surface for good air circulation.
2. Always Spin Balanced Loads: Make certain that you are always spinning a balanced load.
The centrifuge has a unique counter balanced motor mounting design which, along with it's
rubber suction feet, produces excellent vibration dampening. However, out–of–balance loads
may break glass test tubes and may produce unsatisfactory separation results. Proper load
balancing will improve sample separation and extend the life of the centrifuge. Refer to page 7
on balanced loads for additional information on balancing the load.
3. Keep the Tube Holders Clean: NOTE: Always follow the safety guidelines of your laboratory
to properly clean up and/or dispose of materials in the event that a substance known to be
potentially toxic, radioactive or contaminated with a pathogenic microorganism is spilt in or on the
centrifuge. Small glass fragments left in the tube holder after a tube breakage may adhere to
the next test tube inserted in that holder. When this tube is handled, these fragments may
puncture protective gloves and lacerate the operator's fingers or hand. Remaining fragments
may provide stress points on subsequent tubes and result in additional breakage. If a tube
breakage occurs, carefully remove the tube holder. Properly dispose of the sample and tube
fragments and thoroughly clean both the inside and outside of the tube holder. Insert a new tube
cushion (if necessary) and replace the tube holder in the rotor.
4. Motor and Electrical Maintenance: The 642VFD, 642VFD-Plus, and 642VES uses a brush-
less permanent split capacitor AC motor. It should not need servicing for the life of the centri-
fuge. The electrical components are selected for high reliability and should not need service.
5. Tube Holder Replacement: It is recommended that the tube holders be replaced after 24
months of use.
6. Remove Accessories Before Moving: All tube holders, samples, and caps must be removed
from the rotor chamber before transporting or storing the centrifuge to prevent damage and
injury.
Cleaning and Disinfection:
To prolong the life of the centrifuge cleaning and disinfection is recommended every six months,
or whenever there is a spillage or tube breakage. Contaminants must be removed immediately, or
corrosion and premature degradation of components can occur.
1. Unplug the centrifuge before cleaning.
2. Apply cleaning solutions with a towel or cloth. Do not submerge the centrifuge in water or other
cleaning solutions as this will cause damage and void the warranty.
3. ONLY isopropyl alcohol, soap and water, or a 10% (5500 PPM) bleach solution should be
used for cleaning and disinfection of the centrifuge and accessories.
4. All surfaces must be dried immediately after cleaning and disinfecting.
5. TBQ Germicidal products shall not be used, as they will cause damage to the centrifuge and
void the warranty.
6. The use of fully/partially halogenated hydrocarbons, ketones, esters, ethers, benzyls, ethyl
benzenes, and all other chemicals not prescribed by the manufacturer shall not be used as
they may cause damage to the rotor chamber, rotor, tube holders, accessories and centrifuge
exterior and void the warranty.
7. It may be necessary to remove the rotor and clean the rotor chamber. Follow the instructions on
page 7 to remove and reinstall the rotor.
