Introduction
The LW Scientific Zip-IQ TT centrifuge is a 6-place test tube centrifuge for spinning blood, urine, and other fluids in
0.5ml to 15ml test tubes and microtubes. The unit is very small, conserving counter space in the lab, but also sturdy
with suction-cupped feet for stability. The digital controls allow speed and time to be adjusted with the touch of a
finger and will show real-time speed and time remaining. The maintenance-free, brushless motor spins at 5,000rpm
(2,500g) producing serum in as little as 5 minutes. Slow the speed to 2,000rpm (400g) to spin urines in 5 minutes. The
auto-brake stops the rotor in 10 seconds, and the lid opens automatically upon completion.

Warranty
LW Scientific instruments have a one (1) year limited warranty. This warranty is not valid on normal wear and tear, cosmetic
damages caused by chemicals, solvents, and/or cleaning solutions, as well as acts of God.
Please register your product online at: www.LWScientific.com/warranty_form.
Important: Warranty information must be completed within 30 days of purchase.
Installation and Setup
Remove the centrifuge from the shipping container and inspect for any possible shipping damage. If the centri-
1
fuge appears to be damaged, please contact LW Scientific or your distributor immediately.
Read the instruction manual in full before operating. Store the operation instructions in a safe place, easily accessi-
2
ble by the trained staff that will be operating the centrifuge.
Place the centrifuge on a sturdy, level surface. Using the emergency release lever underneath the centrifuge,
3
open the lid. Verify that there are no loose objects or packing material in the tube chamber. DO NOT LOAD TUBES
AT THIS TIME.
Using the included hex wrench, verify that the silver rotor screw in the center is tight. Verify that there are no tubes
4
or inserts in the rotor.
Close the lid, ensuring that it clicks and locks.
5
Plug the power adapter into the rear of the unit, and plug the cord into an outlet. Press the POWER button to turn
6
the unit on. The LCD display should light up.
Test the unit: Set the time at 3 minutes, and set the speed at 1,000 rpm. Press the START/STOP button. The unit
7
should come up to speed with no vibration and a smooth and quiet sound. Second, set the speed at 5,000 rpm
and run again. If there are unusual vibrations or sounds, stop the unit and contact your distributor or LW Scientific.
Loading and Operation
Spin only balanced loads. Ensure that tubes of similar size and equal weight are placed opposite of each other, or
1
place 3 equal tubes in a triangle as pictured below. Use a water-filled tube as a balance tube if necessary. Proper
balancing will improve sample separation and extend the life of the centrifuge. Spinning out of balance loads may
break test tubes or damage the centrifuge.

Loading and Operation Continued
Ensure that test tubes are supported from the bottom and not hanging by their caps. Use inserts as follows:
2
3ml-4ml tubes (13mm x 75mm)
White Inserts
These support short, skinny tubes
5ml-6ml tubes (13mm x 100mm)
These support tall, skinny tubes
Black Inserts
7ml-15ml tubes(16mm x100mm - 120mm)
Use the openings in the rotor
No Inserts
Note:
Not hanging
by cap
Green Inserts
0.5ml - 2.0ml microtubes
Microtubes ARE designed to hang
by the rim of the tube.
Note:

Set the speed and time as recommended on page 4.
3
Press the START/STOP button to run the cycle. The unit will stop on its own, beep, and open the lid upon completion.

Note: Always ensure rotor is secure before each use.
Care, Maintenance, and Troubleshooting
The Zip-IQ motor is designed to be maintenance-free. With proper care, this centrifuge will provide years of service.
However, if repairs should be needed, please contact LW Scientific.
Use only quality test tubes that are rated for the g-forces utilized. Lower-quality tubes may fracture and allow
1
contents to leak out of tube.
Never force tubes into the rotor. The rotor was designed to hold the most common sized test tubes.
2
Clean with common laboratory disinfectants regularly. Do not allow moisture to seep into the centrifuge and do
3
not immerse the electrical components in any liquid during the cleaning process.
Because of safety issues with high g-forces in a centrifuge, it is recommended that rotors be inspected monthly for
4
wear and fatigue. If there is any indication of wear, the rotor should be removed from service. Contact LW Scientific for return instructions so the rotor can be evaluated by a technician for repair or replacement. After 2 years of
service, it is recommended that rotors be returned to LW Scientific for inspection or replacement.
Following these procedures will ensure safety of lab personnel as well as extend the life of the centrifuge.

Recommended Fluid Speeds and Times
Set the speeds and times as follows, or defer to clinical protocols if different:
Fluid Tube Size Inserts Speeds Times
Blood Large (6ml-15ml) None or Black 5,000rpm 5 minutes
Blood Small (3ml-5ml) White 5,000rpm 6 minutes
Blood Microtubes (0.5ml-2.0ml) Green 5,000rpm 7 minutes
Urine 10ml-15ml urine tubes None 2,000rpm 5 minutes
Fecals 10ml-15ml fecal tubes None 1,700rpm 6 minutes
NOTE: G-Force is based on radius and speed. Using inserts for smaller tubes and microtubes reduces radius therefore
reduces g-force, hence the spin times must be slightly longer in smaller tubes to achieve clear serum separations.
Times and speeds can be adjusted based on visual results and clinical protocols.
