Wait for complete stop. Use the manual emergency lid release if power is totally lost. Lid latch mechanism failure or microswitch misalignment.
Shut down immediately. Check tube weights and rebalance the rotor symmetrically. Ice buildup or failing compressor.
CFC-free refrigerant (Standard in later production runs) 2. Installation and Safety Setup
To the uninitiated, it looked like a standard piece of technical documentation from a bygone era, complete with meticulously hand-drawn technical diagrams, exploded views of the rotor assembly, and troubleshooting charts that predicted every mechanical failure known to science. But to the scientists who relied on it, the manual was the lab’s ultimate spellbook. eppendorf 5402 manual
Tracks remaining run time. Setting the timer below 1 minute or above 99 minutes typically engages the continuous run mode.
: Adjustable from -9°C to 40°C (-16°F to 104°F), making it ideal for maintaining the integrity of delicate biological samples.
If your samples are temperature-sensitive, set the desired temperature and press the Fast Cool button. Keep the lid closed during this process. Loading the Rotor Wait for complete stop
Wipe down the rotor chamber, rotor, and lid weekly using a mild detergent or a 70% isopropyl alcohol solution. Avoid aggressive chemical cleaners or bleach, which can corrode the aluminum.
Generations of PhD students had come and gone, yet the 5402 remained anchored to the heavy oak workbench in corner bay 4. It had outlived three department chairs, countless software upgrades on the lab computers, and a minor electrical fire in the breakroom.
From various lab forums and service records, certain issues are known to appear on the Eppendorf 5402. Here are some common ones and their potential solutions. Shut down immediately
Turn off power for 5 minutes, restart. If it persists, the tachometer sensor may need replacement. Compressor failure or blocked ventilation grids.
Press the Start button. The speed display will gradually climb to your programmed RPM. Unloading Samples
The Eppendorf 5402 is a high-quality, versatile centrifuge designed for various laboratory applications. As with any complex equipment, understanding its operation, maintenance, and troubleshooting procedures is crucial for optimal performance and longevity. This post aims to provide an in-depth look at the Eppendorf 5402 manual, covering essential aspects of its use and care.
Speed sensor issues. This often requires professional calibration.
Maintain at least 10 cm of free space around all sides for proper cooling air circulation. Do not block the ventilation openings.
