MX12 Micro-Combo Centrifuge
Instruction Manual
Designed, Engineered &
Assembled Proudly in America
Introduction
The LW Scientific MX12 Micro-Combo centrifuge spins microhematocrit (PCV) and/or microtubes in one small unit. The
MX12 Micro-Combo is designed, engineered, and assembled in Atlanta, GA. This all-metal-construction unit is small,
conserving valuable counter space in the lab, but also sturdy and heavy 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 powerful, maintenance-free, brushless motor spins at 12,000 rpm producing serum and PCV results in 3
minutes. The included reader disk allows tubes to be read while still on the rotor. The MX12 Micro-Combo centrifuge is
the smart choice for any clinic or laboratory.

•Two 5-amp 250v Fuses (Pre-installed) LW Scientific packs each MX12 Micro-Combo centrifuge with utmost care. All units undergo a QC check prior to shipping from LW Scientific headquarters in Lawrenceville, GA to ensure proper operation. Examine the outer and inner containers for any visible damage, and retain the packing material. - Page 3 Selecting and Changing Rotors Place the centrifuge on a sturdy, level surface. Verify that there are no loose objects or packing material in the tube chamber. Select a rotor and slide it down over the motor shaft. WARNING: Please use the provided thumbscrew / hex screw that comes with the rotor you are installing, DO NOT use screws for other rotors.

Page 7: Care And Maintenance
Because of safety issues with high g-forces in a centrifuge, it is recommended that rotors be inspected monthly for 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. -
