Eppendorf, Hauppauge, NY, has launched a new line of aluminum rotors. Rotors 18×1.5mL for microcentrifuge 5418 R and 6x50mL rotor for multipurpose centrifuges 5804 R and the 5810 R now have a lid locking mechanism. The QuickLock lid system requires a quarter turn to have certified aerosol-tight containment. A low rotor weight of the fixed angle rotors has also been achieved by routing out all metal that is not needed for safety or performance. Each Eppendorf rotor is made with 100% recyclable aluminum.
