Construction
The enclosures of the HENRY SCHEIN PowerSpin™LX Centrifuges are made of high
impact plastic, which is acid and reagent resistant. The internal chamber is made of
stainless steel. A safety switch is built into the lid and disconnects the power to the motor
whenever the lid is unlatched. The motor is mounted on rubber mounts to provide quieter
running and less vibration. The rotor chamber can be easily cleaned and disinfected.
Performance
Maximum speed depends on the number and size of the test tubes being spun.
PowerSpin™LX is variable speed unit, with 6 or 8 place rotor. The maximum speed is
4,000 rpm.
Accessories
Adapters are available to accommodate various tube sizes. Contact Henry Schein for
details.

Unpacking and Installation
The centrifuge is first packed in a styrofoam and then put in a carton box for shipping.
Please examine the shipment upon receipt and retain all packing until the unit has been
tested. The warranty excludes any damage caused by shipping.
Inspect for any possible shipping damage. If you note any damage, please contact
HENRY SCHEIN. Save the original packaging. If it becomes necessary to return the
instrument to us, we ask that it be returned in the original packaging.
Unpack the shipping carton carefully and verify that the shipment is complete. It should
include the following items:
PowerSpin™ centrifuge (LX) 1 unit
Power cord 1 pc.
Operation manual (LX version) 1 pc.
No on-site installation is required. Follow simple procedures below to set the centrifuge
up:
Take the centrifuge from the styrofoam and place it on a sturdy flat surface.
Press the lid latch release button located on the right side and open the centrifuge
cover. A special packing styrofoam disc is packed inside the lid of the centrifuge to
prevent the rotor or shields from moving during shipping. REMOVE THIS
PACKING DISC PRIOR TO OPERATION OF THE CENTRIFUGE
The centrifuge rotor is pre-installed. No rotor installation and calibration is required.
The power inlet is located in the back of the centrifuge. Plug in one end of the power
cord to the inlet and the other end to a power outlet.
Turn the speed control counterclockwise to “0” rpm.
CAUTION: Make sure the voltage of the power source matches the voltage input of
centrifuge.
Operation
1. Set the timer control to “off”.
2. Plug the centrifuge into a power source outlet. Make sure the voltage is correct.
3. Turn the power rocker switch in rear of unit to “on” position.
4. Open the lid by pressing the lid-opening button.
5. Place the specimen tubes into the tube shields of the rotor.
CAUTION: Make sure that the specimen tubes are balanced; see safety
section below.
6. Close the lid firmly.
7. Set the speed control knob at or close to “0” rmp.
8. Set the timer clockwise to the desired time.
9. Rotate the speed control knob slowly to the appropriate speed.
For example, Blood at 3,400 or Urine at 2,000- 2200 rpm.

10. After the centrifuge rotor has come to a complete stop (following the end of
the run bell), open the lid.
Safety
Your PowerSpin™LX centrifuge is a carefully designed and built instrument. When
operated properly, it presents no safety hazards. However, please take note of these safety
precautions.
Lid NEVER OPEN THE LID UNTIL THE ROTOR HAS COME TO A
COMPLETE STOP!
Load Balance Always make sure that the load is balanced before operating
the instrument.
It is very important that test tubes with equal loads are placed opposite each other in the
rotor. Also, when spinning a single specimen tube, another specimen tube of the same
size filled with water must be installed directly across from the specimen tube to maintain
balance. If the centrifuge is not properly balanced, damage could occur. If excessive
noise or vibration is noticed during a run, stop the centrifuge and recheck the balance.
Maintenance
This centrifuge is designed to be relatively maintenance free. The motor is a brushless
type and has permanently sealed bearings so oiling is not necessary. A surface cleaner
such as Formula 409 can be used to clean the outside of the instrument. The rotor
chamber and cover can be disinfected with a mild solution of bleach or other disinfecting
liquid and allowed to dry. Do not drench or immerse the unit in any liquid! Be sure to
disconnect the power before attempting to clean.
Routine Rotor Inspection and Maintenance
All centrifuge rotors should be removed and inspected for damage, defects or other
problems:
-Before initial use.
-Each time the rotor is removed for cleaning.
-At least every 6 months.
Plastic rotors and tube shields should be replaced every 12 months (once each year).
What to do if your inspection finds rotor or tube shield damage, defects or other
problems? If you detect any problems or damage, or defects in your centrifuge rotor or
tube shields discontinue use of the centrifuge and rotor immediately! Do not under any
circumstances continue to use a rotor that you think has damage as it could create a
safety problem.
Contact support at HENRY SCHEIN immediately at 800-588-9776 or 732-274-1155.
Please be prepared with the serial # (found on the rear of the machine near the electrical
plug) and any information you may have about where and when it was purchased.

Calibration
According to Code of Federal Regulations Title 21, centrifuges require verification or
calibration as follows:
1) Before initial use; 2) after repair or adjustments; and 3) 6 month after use. The
centrifuge timer, however, should be checked for accuracy at least every 3 month.
2) The speed should fall within ±100 rpm of the speed display.
3) The timer is a mechanical one and designed to be accurate to 5 min ± 30 sec.
Electrical Shock Hazard
Do not attempt to operate this instrument near water or liquid spill. Unplug the unit
before cleaning or repairing. Periodically check the condition of the power cord for cuts
or damage. Do not operate with a damaged cord.
Biohazard
If a tube breaks, a biological hazard may exist. Unplug the instrument. Clean using
approved laboratory procedures. Always wear the proper protective clothing and gloves.
Use a suitable disinfectant and dispose of the sample properly. Refer to the guidelines set
forth by OSHA, CLIA, etc.

power light to illuminate could indicate a need for a new fuse when the unit is
properly plugged in turned on and the lid closed.
2. Excessive noise when running. If the noise is irregular or different in tone, be
sure that there is no paper or debris in the rotor or rotor chamber. Make sure
that the load is balanced.
3. Indicator light fails to light.
a) Unit is not turned on
b) Lamp needs to be replaced
c) Fuse is blown
4. Fuse Replacement:
CAUTION: DISCONNECT THE POWER CORD BEFORE REPLACING FUSE.
