The Eppendorf Centrifuge 5402 is a classic, high-performance refrigerated microcentrifuge designed for quick-spin applications, pelleting of macromolecules, and temperature-sensitive biological separations. Known for its robust build quality and exceptional reliability, this legacy instrument remains a staple in molecular biology, biochemistry, and clinical laboratories worldwide.
: Modern centrifugation relies on the strict maintenance of center-of-mass alignment. The paper discusses the physics of rotor imbalance—where even a 0.1g variance at 14,000 RPM translates into significant destructive torque. The RCF Equation
Reading the 5402 manual is a time capsule. It includes:
Always inspect the rotor for signs of corrosion or "pitting" before use. eppendorf 5402 manual
Plug the unit directly into a grounded electrical outlet matching the voltage specified on the manufacturer’s ID plate (typically 120V or 230V). Avoid using extension cords. Critical Safety Rules Never override the lid-locking mechanism. Never move the centrifuge while the rotor is spinning.
is a reliable, high-performance, and compact laboratory instrument designed for molecular biology, biochemistry, and clinical applications. Known for its durable construction and precise cooling capabilities, this centrifuge is a mainstay in many research laboratories. This article provides a comprehensive overview of the Eppendorf 5402 manual
If the door is opened during a run, the motor stops automatically. Ending the Run The Eppendorf Centrifuge 5402 is a classic, high-performance
Remove the rotor and inspect it for signs of corrosion, hairline cracks, or pitting.

Routine maintenance extends the life of the 5402 significantly. The paper discusses the physics of rotor imbalance—where
Operating an unbalanced rotor causes severe vibration, triggers an automated shutoff, and can permanently damage the spindle. Step 3: Setting Parameters Close the lid firmly until the safety latch clicks. Adjust the dial to your required duration. Set the Speed dial to the desired rpm or g-force.
A dial to set the target cooling temperature.
Stop the run immediately. Re-balance the tubes and verify the rotor nut is tight. Symmetrical loading was not maintained. Rearrange opposing tubes to match weights perfectly. Chamber not cooling Condenser coils blocked, or refrigerant leak.
The 5402 model features intuitive controls for speed, time, and temperature. Loading the Rotor
