Introduction
Installation and Set-up
USA E8 Centrifuge
The LW Scientific E8 is available in the E8F (Fixed speed), E8V (Variable speed), and E8D
(Digital speed). The E8F is an 8-place centrifuge that is designed for blood separations at a
fixed speed of 3500 rpm only (1534 g-force). The E8V and E8D will separate blood at 3500
rpm and can be slowed to separate other fluids at lower g-force, such as urine specimens
as outlined by C.L.I.A. regulations.
30-minute mechanical timer (E8F and E8V), ON/OFF switch (indicator light), 8-tube capacity
(3-15ml), lid safety switch (unlatching the lid turns the centrifuge off), one-piece plastic hous-
ing, high impact plastic lid allows for observation of samples and strobing for speed calibra-
tions.
Remove the centrifuge from the shipping container and inspect for any possible shipping damage. If the centrifuge
appears to be damaged from shipping, please contact your distributor immediately.
Read and fill out the warranty form online. The warranty form documents your purchase. Failure to complete the
warranty form may void any warranty claims on the unit.
Place the centrifuge on a sturdy, level surface. Unlock lid latch (U) and open to verify that there are no loose objects
or packing material in the tube chamber and that all tube shields are properly “seated.”
The large plastic tube shields are designed to hold large test tubes up to 15ml, and the smaller tube shields fit inside
the large shields for spinning shorter test tubes (75mm length). Special size rubber cushions can be ordered from LW
Scientific. Verify that all tubes are installed and balanced (See 7 below).
Verify that the power switch on the front of the unit is in the OFF position. Connect the power cable to the power
supply adapter, and then connect the power supply adapter to the back of the centrifuge. Plug the power cable
into an approved and properly grounded outlet. Do not insert specimen tubes at this time!
Close the lid, turn the latch to the (L) position and turn power switch ON. For fixed and variable units, turn the timer
to 5 minutes. For digital units, adjust speed to 3500rpm, set the timer to 5 minutes, and press RUN. If there is a smooth
whirring sound and the unit accelerates with little or no vibration, your E8 centrifuge is ready to operate. If there are
loud, unusual sounds or if you experience excessive vibration, immediately turn the unit off. DO NOT OPERATE - Con-
tact your dealer or LW Scientific, Inc.
For fixed and variable speed units, the mechanical timer should be turned past 5 minutes to engage the bell. The
timer can be turned forward or backward to select time.
After each run cycle has ended, the lid must be opened and closed before the next cycle is run. This allows for
re-loading and re-balancing each load.
Spin only balanced loads. Make sure that all tube shields are filled with equal weight tubes. Tubes of equal weight
and size should be placed opposite each other. Use water-filled tubes to provide balance if necessary. Proper
sample balancing will improve sample separation and will extend the life of the centrifuge. Out of balance loads
may break glass test tubes. DO NOT OPEN WHILE SPINNING.
