Eppendorf 5402 Manual Updated «UPDATED – 2025»

The Eppendorf Centrifuge 5402 is a legacy refrigerated benchtop microcentrifuge known for its reliability in molecular biology applications. While newer models like the Centrifuge 5420 have succeeded it, maintaining the 5402 requires adhering to original technical specifications and updated maintenance standards. Core Technical Specifications Maximum Speed: 14,000 RPM (approx. 16,000 x g). Temperature Range: -4∘Cnegative 4 raised to the composed with power C 40∘C40 raised to the composed with power C , providing stable cooling for sensitive samples.

The Eppendorf 5402 manual is an essential resource for anyone using this pipette. By reading and understanding the manual, users can:

The 5402 is designed for high-speed separation of small sample volumes, typically utilizing 1.5 mL and 2.0 mL Eppendorf tubes . Key technical specifications include: Speed Range: Variable speeds up to 14,000 RPM. Temperature Control: eppendorf 5402 manual updated

Performance: Variable speeds up to 14,000 RPM (approx. 16,000 x g).

While the Eppendorf 5402 is a legacy model (often succeeded by the 5424 and 5430 series), it remains a staple in many laboratories. The "updated" manual typically refers to the later technical documentation releases (often identified by order number 5402 300.310-xx or similar variants issued in the early 2000s) which superseded the original operating instructions, specifically addressing safety interlocks and motor maintenance. The Eppendorf Centrifuge 5402 is a legacy refrigerated

Critical Update: The "Quiet Cycle" Bug

The updated service manual acknowledges a firmware quirk in units manufactured between 1998 and 2002. After 1,000 hours of runtime, the refrigeration unit may enter a "quiet cycle" where it fails to cool but does not trigger an error code. The updated manual provides a workaround: a hard reset via holding the "Temp" and "Start" buttons simultaneously for 10 seconds.

Short summary piece: "Eppendorf 5402 Manual — Updated"

The Eppendorf 5402 is a compact, electronic single-channel pipette widely used for life‑science labs requiring precise low-volume liquid handling (0.5–10 µL, 2–20 µL, 10–100 µL, or 20–200 µL models). An updated manual clarifies operation, maintenance, calibration, troubleshooting, and safety to reduce user error and extend instrument life. 16,000 x g)
