Operating the 5402—as outlined in its classic operating instructions—is a sequence of careful steps that every lab tech learns:
: Websites like ManualsLib ( www.manualslib.com ) or Labomec ( www.labomec.com ) might have the manual you're looking for. You can search using the model number "Eppendorf 5402".
Never operate the centrifuge without a properly balanced load. Even a weight difference of 0.1g between opposite tubes can cause excessive vibration.

Elena smiled. She placed her thumb over the heavy steel latch, counting silently to ten. She pressed the start button again.
: Before the high-speed descent, you must secure the rotor lid . The safety manual warns that even minor scratches on accessories can lead to "severe internal material damage" if they fail at high speeds.
Before powering on the unit, ensure the centrifuge is placed on a level, stable surface. Adequate ventilation is required, especially for the cooling fans located at the rear and sides of the machine. Operating the 5402—as outlined in its classic operating
Ensure the knurled rotor nut is securely tightened before attaching the rotor lid. Troubleshooting Common Issues
Select speed up to 14,000 RPM (increments of 100 RPM). Set Time: Choose a run time from 0 to 99 minutes. Start: Press the "Start" button.
The Eppendorf 5402 is a compact, high-speed refrigerated centrifuge specifically designed for centrifuging small volumes in microcentrifuge tubes (1.5/2.0 mL). It is widely used for cell harvesting, DNA/RNA preparation, and protein separation. Eppendorf 5402 Refrigerated Microcentrifuge Max Speed: 14,000 rpm Max RCF (g-force): 16,400 × g Capacity: 24 positions for 1.5/2.0 mL tubes Temperature Range: -9°C to +40°C Refrigeration: CFC-free coolant Key Feature: Fast cool function ( Even a weight difference of 0
The 5402 could swing between a fixed-angle rotor (F-45-18-11) and a swinging-bucket rotor (A-8-11). The manual contains the master tables showing which plastic or steel adapters fit which tubes—from 0.4 mL microtubes to 1.5/2.0 mL standard tubes. Put a 0.5 mL tube in the wrong adapter, and you risk a rotor imbalance or, worse, a broken tube.
