5402 Manual - Eppendorf
For labs that still rely on the 5402, the manual is not just a reference—it’s a survival guide. Without it, ordering replacement rotors (like the discontinued 5402 350.008) is impossible. Without the imbalance calibration procedure, the machine will shut down after every run.
The good news: A dedicated community of lab archivists has preserved the manual in places like the Internet Archive (search "Eppendorf 5402 Instruction Manual") and LabWrench. If you own a physical copy, consider scanning it at 600 dpi and uploading it. You might save a grad student’s experiment—or keep a classic centrifuge spinning for another decade.

The Eppendorf 5402 centrifuge is a popular choice among laboratory professionals due to its reliability, flexibility, and user-friendly interface. It is designed to handle a wide range of centrifugation applications, including microcentrifugation, with a maximum speed of 14,000 rpm and a variety of rotor options for different tube sizes and types. For labs that still rely on the 5402,
The Eppendorf 5402 is pre-digital, so errors are indicated by behavior, not LCD messages.
| Problem | Manual's Likely Cause | Solution | | :--- | :--- | :--- | | Centrifuge won't start | Lid not locked; motor thermal cutout | Check lid knob; wait 30 min for motor cooling | | Violent shaking at startup | Imbalanced load or loose rotor | Re-balance tubes; re-tighten rotor nut | | No deceleration brake | Brake resistor failed (electronics) | Service required (see repair manual) | | Unusual grinding noise | Motor bearing failure or debris in chamber | Stop immediately. Clean chamber. If noise persists, replace bearings | First, a brief history
First, a brief history. The Eppendorf 5402 was introduced as a non-refrigerated, variable-speed benchtop centrifuge designed for spinning microcentrifuge tubes (1.5–2.0 mL) and PCR strips. Unlike its refrigerated sibling (the 5403), the 5402 relies on ambient air cooling.
