Eppendorf aluminum rotors have been optimally crafted to take your centrifuge experience to an all new level. Rotors 18x1.5mL for microcentrifuge 5418 R and 6x50mL rotor for multipurpose centrifuges 5804 R and the 5810 R now have a lid locking mechanism that makes every day routines faster, easier and more enjoyable! The QuickLock™ lid system requires only a quarter of a turn to have certified aerosol-tight containment, providing easy access and safe centrifugation of precious samples. An audible “click” signal clearly indicates that the lid is securely fastened. A low rotor weight of our fixed angle rotors has also been achieved by routing out all metal that is not needed for safety or performance. This allows for easy loading and unloading of the rotor and requires less power consumption during centrifugation. Eppendorf’s advanced rotor design is not only an ergonomic solution for your lab, but also a green one! Each Eppendorf rotor is made with 100% recyclable aluminum.
