The Ultimate Eppendorf 5402 Manual and Operator's Guide The Eppendorf Centrifuge 5402 is a classic, high-performance refrigerated microcentrifuge designed for research, clinical, and molecular biology laboratories. Known for its robust build and reliable temperature control, this legacy instrument remains a staple in many labs today. eppendorf 5402 manual
Configures the duration of the run. Setting this dial to the "Hold" or infinity symbol enables continuous operation until manually stopped.
Must be placed on a level, rigid, and resonance-free laboratory bench.
The Eppendorf 5402 primarily uses (fixed-angle, 18-place for 1.5/2.0 mL tubes) and Rotor A-8-11 (for 8-tube PCR strips). The manual provides diagrams showing exactly how to seat the rotor onto the motor shaft. Important rules from this section: Open the lid, check sample weights, redistribute tubes
Locate the small plastic plug or opening underneath or on the side of the unit (depending on the exact manufacturing year batch).
: The most critical rule. You never start a run without ensuring the rotor is perfectly balanced. If you only have one sample, the "balancing tube" (a tube filled with an equal volume of water) becomes your best friend.
Turn the temperature dial to the desired setting. Use the "Fast Cool" function to pre-cool the rotor chamber before spinning sensitive RNA or protein samples. Dimensions: A tabletop unit requiring approximately cm of
