Eppendorf SPACER(S) 5721411343

This item name appears to describe an Eppendorf spare part called a spacer. Eppendorf manufactures rotor/stacking spacers used with Vacufuge vacuum concentrators and certain centrifuge rotors to enable stacking of fixed-angle rotors, increasing sample throughput. I could not find a manufacturer product page or authorized-distributor listing that matches the exact part number 5721411343; available Eppendorf documentation and distributor listings instead describe rotor spacers (for example, Eppendorf part 022822101) that are explicitly for stacking rotors in Vacufuge models and increasing capacity for 0.5 mL and 1.5/2.0 mL tube rotors.

Key Features:

• Designed for stacking fixed-angle rotors in concentrators/centrifuges (rotor spacer function)
• Compatible example: used with rotors F-45-72-8 (72 × 0.5 mL) and F-45-48-11 (48 × 1.5/2.0 mL) in Vacufuge Plus (manufacturer example part 022822101)
• Increases run capacity (example: stacking can raise capacity to 96 or 144 samples depending on rotor combination)
• Sold individually as an accessory for Eppendorf Vacufuge/rotor systems

Advantages:

• Enables safe stacking of compatible rotors to increase sample throughput per run
• Maximizes equipment utilization and reduces number of runs needed
• Simple accessory replacement—manufacturer-supported spare part for Vacufuge/rotor systems
