The Eppendorf 5425R Refrigerated Centrifuge is a whisper-quiet microcentrifuge designed for a wide range of molecular and cell biology applications. Featuring an advanced cooling system, it provides precise temperature control, ensuring reliable cooling at 4C even at maximum rotor speed. The fast pre-cooling function reduces wait times, bringing the rotor chamber from 21C to 4C in just 8 minutes. With a broad speed range from 100 RPM to 15,060 RPM, the 5425R is highly versatile, accommodating diverse workflows. This centrifuge supports a comprehensive range of six rotors, expanding its compatibility with various sample types, such as micro test tubes, PCR strips, and spin columns. The included FA-24x2 Fixed Angle Rotor achieves the maximum speed of 15,060 RPM, delivering consistent and efficient performance. Compact, user-friendly, and reliable, the 5425R is an indispensable tool for temperature-sensitive sample processing.
The included FA-24x2 Fixed Angle Rotor reaches a maximum speed of 15,060 RPM. Please confirm this rotor meets your application needs and request a different rotor, if necessary. Available rotors can be found in our Rotor Compatibility Guide.
