Data herein has been verified and validated and is believed adequate for the intended use
of the centrifuge. Because failure to follow the recommendations set forth in this manual
could produce personal injury or property damage, always follow the recommendations
set forth herein. Du Pont does not guarantee results and assumes no obligation for the
performance of rotors or other products that are not used in accordance with the
instructions provided. This publication is not a license to operate under , nor a recommendation to infringe upon, any process patents.
Publications prior to the Issue Date of this manual may contain data in apparent conflict
with that provided herein. Please consider all data in this manual to be the most current.
NOTES, CAUTIONS, and W ARNINGS within the text of this manual are used to emphasize
important and critical instructions.
WARNING:A W arning informs the operator of a hazard or an unsafe practice that could
result in personal injury, affect the operator’s health, or contaminate the
environment.
CAUTION:A Caution informs the operator of an unsafe practice that could result in
Certain potentially dangerous conditions are inherent to the use of all centrifuges. To
ensure safe operation of this centrifuge, anyone using it should be aware of all safe
practices and take all precautions described below and throughout this manual.
WARNING
When using radioactive, toxic, or pathogenic materials, be aware of all characteristics of the
materials and the hazards associated with them in the event leakage occurs during
centrifugation. If leakage does occur, neither the centrifuge nor the rotor can protect you
from particles dispersed in the air. To protect yourself, we recommend additional precautions
be taken to prevent exposure to these materials, e.g., use of controlled ventilation or isolation
areas.
Always be aware of the possibility of contamination when using radioactive, toxic, or
pathogenic materials. Take all necessary precautions and use appropriate decontamination
procedures if exposure occurs.
The use of sealed rotors, buckets and/or sample containers will provide increased protection
from contamination during routine operation. However, these items will not guarantee
contamination protection from accidents resulting in damage to the rotor or buckets. Do not
run hazardous materials in the centrifuge unless placed in a biohazard enclosure and operated
using all appropriate safety precautions.
Safety
Never use any material capable of producing flammable or explosive vapors.
Never exceed the maximum rated speed of the installed rotor; to do so can cause rotor failure.
Always reduce (derate) rotor speed as instructed in this manual whenever:
•the rotor speed/temperature combination exceeds the solubility of the gradient material
and causes it to precipitate.
•the compartment load exceeds the maximum allowable compartment load specified. See
Chapter 3, Operation, page 3-6.
Failure to reduce rotor speed under these conditions can cause rotor failure.
CAUTION
Do not run or precool a rotor at the critical speed, as this will have a detrimental effect on
centrifuge component life. See Chapter 3, page 3-3.
Do not operate the centrifuge with a rotor out of balance. To do so can cause damage to the
centrifuge drive assembly.
Do not operate centrifuge without a rotor properly installed: rotor cover must be on and
locked in place, and the rotor locked to the centrifuge drive. See rotor instruction manual.
The centrifuge can be damaged if connected to the wrong voltage. Check the voltage before
plugging the centrifuge into a power source. Du Pont is not responsible for incorrect
installation.
Always maintain the centrifuge in the recommended manner. See Chapter 4, Maintenance.

Centrifuge Description
The R T6000B combines the features of the tabletop centrifuge and those of the larger
refrigerated centrifuge in a compact tabletop instrument. It is similar to other SORV ALL
Tabletop Centrifuges, with an added refrigeration system that consists of an evaporator/
rotor chamber and a low-temperature condensing unit. The system is designed to
maintain temperature within 1°C, while in the operating range of –5°C to +25°C. The
T6000B is a non-refrigerated tabletop centrifuge.
Both the RT6000B and T6000B feature a closed-loop speed control and have a seethrough chamber door that allows rotor calibration and visual inspection of a run in
progress. The chamber door is counterbalanced for easy opening and safe closing. The
lid latch is locked manually by turning the door release knob counterclockwise to the
LOCKED position, then mechanically an interlock engages when the rotor begins spinning
to prevent the chamber door from being opened during operation. The gyro-action, selfcentering drive has a diamond hex-shaped drive spindle which assures proper seating of
rotors. The centrifuges also have a slow-start feature that slowly accelerates the rotor from
0 to 600rpm.*
The table below lists the rotors available for the RT6000B and T6000B Centrifuges. For
more information about other rotor accessories and tubes refer to the most current
