The Eppendorf Centrifuge 5402 remains a classic workhorse in molecular biology, biochemistry, and clinical laboratories worldwide. Renowned for its robust build and dependable refrigerated performance, this microcentrifuge is essential for pelleting nucleic acids, spinning down proteins, and preparing clinical samples.
The Eppendorf 5402 was once a mainstay in laboratories, a robust and reliable refrigerated microcentrifuge designed for the precise processing of temperature-sensitive samples. It was engineered as a versatile "three-in-one" instrument—capable of serving as a high-capacity general-purpose centrifuge, a high-speed unit for cell lysates, and a micro-centrifuge for DNA precipitation. Its adaptability made it a popular choice for a wide array of molecular biology, biotechnology, and clinical diagnostic applications.
The 5402 was built for reliability with a small benchtop footprint:
Proactive maintenance extends the lifespan of the Eppendorf 5402 and prevents costly laboratory downtime. eppendorf 5402 manual updated
The most reliable source currently is , which hosts a 9-page instruction manual covering the 5402, the 5415 C micro-centrifuge, and the F-45-18-11 rotor. This document is the cornerstone for understanding the device. While other lab equipment forums like LabWrench may host user discussions and Q&A for the 5402, they explicitly state that no official manuals are available directly on their site.
The Eppendorf 5402 is a versatile pipette designed for a wide range of laboratory applications. Some of its key features include:
If a tube breaks containing infectious agents, the operator must wait 30 minutes for aerosols to settle before opening the lid. Wear appropriate PPE. Decontaminate with a 1:10 diluted bleach solution or 70% isopropanol, ensuring the contact time does not corrode the aluminum rotor.
Ensure the rotor has fully stopped. Locate the mechanical emergency release cord/pinhole hidden underneath or on the side of the unit. Use a small hex key or pull-string to manually disengage the latch mechanism. Excessive Vibration or Loud Noise Remove the rotor weekly to clean the drive shaft underneath

– Some early manual versions had vague schematics for the refrigerant type (R134a vs. older CFC-based coolants). Updated addendums clarify that the 5402 uses R134a, and they provide corrected voltage tolerances (±10% of 230V for EU models; ±10% of 120V for NA models).
In the event of a total power failure, you can retrieve your samples using the emergency manual lid release. Disconnect the main power plug from the wall.
Press STOP immediately. Wait for standstill. Clean spilled liquids and re-balance tubes using a scale. Condenser coils blocked; lid seal leaking; low refrigerant. The Eppendorf 5402 was once a mainstay in

However, legacy equipment is only as good as the documentation that supports it. Searching for an is not just about finding a PDF; it is about ensuring operator safety, maintaining calibration compliance (ISO 9001/15189), and extending the lifecycle of a precision instrument.
