Introduction

The newly-redesigned C5 Centrifuge is now designed, engineered, and assembled in the United States. It is available
with multiple rotor configurations, including the standard 8-place 15ml horizontal swing-out rotor, a 24-place 10ml
horizontal bucket rotor, a 4-place horizontal 50ml bucket rotor, as well as many custom rotors for specialty devices. The
C5 features programmable, digital controls and variable speeds up to 5,000 rpm (4,250g) for the swing-out rotor and up
to 4,000 rpm for the bucket rotor, which produces platelet-poor-plasma in minutes. Select slower speeds for other
samples such as urine sediments, fecals, semen, etc. Simply program the time and speed, and touch the start button.
The C5 features double-walled metal construction and a lid that remains locked until the rotor has come to a complete
stop to meet the strictest safety standards in the lab. Maximum tube size for the standard 8-place 15ml rotor is 128mm
long by 17.5mm diameter.

LW Scientific packs each C5 centrifuge with utmost care. All units undergo a QC check prior to shipping from LW

1

Scientific headquarters in Lawrenceville, GA to ensure proper operation. Examine the outer and inner containers for
any visible damage, and retain the packing material. If there is visible damage, please contact the shipper or your
distributor, as our warranty does not cover shipping damage.

Remove the centrifuge from the shipping container and inspect for possible shipping damage. DO NOT OPERATE THE

2

CENTRIFUGE AT THIS POINT.

Please read and complete the warranty form online at LWScientific.com/warranty_form. The warranty form

3

documents your purchase. Failure to fill out the warranty form may void any warranty claims on the unit.

Place the centrifuge on a sturdy, level surface. Plug the power cord into the appropriate power outlet.

4

Turn the power on with the on/off switch on the back of the unit. The power light and digital display should light up.

5

DO NOT OPERATE THE CENTRIFUGE AT THIS POINT.

The lid on the C5 remains locked while at rest and while spinning. To open the lid while at rest push the STOP/OPEN

6

button, then press on the front right corner within 7 seconds to release the lid lock. After 7 seconds, the lid will relock. If
power fails, the lid can be manually opened by inserting the Manual Lid Release Tool (or a small screwdriver) into the
release hole on the front right side of the unit.

Inspect the chamber. Remove all packing material from the chamber, install the rotor (see insert instruction page),

7

and ensure that all the tube shields are in place. Make sure that no tube shields or tube cushions or other pieces have
fallen loose into the bowl. Make sure that the rotor nut is tight using the included Rotor Wrench. DO NOT OPERATE THE

CENTRIFUGE AT THIS POINT.

If you purchased the 8-place rotor, eight rubber tube cushions are included to accommodate smaller tubes. Make

8

sure that all shields and cushions are balanced on the rotor at all times. Proceed to “Operation”.

Troubleshooting

No power: Plug into another outlet. Check the 2 fuses (fuse filament should be visible).
Wobbles and shakes: Remove all tube shields and clean them out. Check for cushions or dried fluids

in tubes. Test run without tube shields or buckets in place.

Makes excessive noise: Tighten rotor nut.
Breaking tubes: Turn the speed down. Check your tube limits. Discard old tubes and try new

ones.
Lid won’t open: If power fails, you must override the lid-lock by pushing the supplied Manual
Lid Release Tool or a small screwdriver into the hole in the side of the unit to
manually disengage the lock while gently pressing downward on the lid.
