Eppendorf SPACER 5721411288

The designation “Eppendorf SPACER 5721411288” refers to an Eppendorf spare part described generically as a spacer. Eppendorf manufactures rotor/stacking spacers for its Vacufuge/concentrator line and for fixed-angle rotors; these spacers are used to stack rotors to increase sample capacity and throughput and are supplied as individual spare/accessory parts. I was unable to find an official Eppendorf product page that explicitly lists part number 5721411288, so the exact SKU-to-application mapping for this number could not be verified against manufacturer documentation.

Key Features:

• Primary function: rotor/stacking spacer to enable stacking of fixed-angle rotors (used with Vacufuge Plus vacuum concentrators).
• Example compatibility (manufacturer example for a rotor spacer): F-45-72-8 and F-45-48-11 rotors (as listed for Eppendorf spacer model 022822101).
• Sold individually as a spare/accessory; intended to increase capacity (stacking can raise capacity to ~96 or 144 samples depending on rotor combination).

Advantages:

• Increases sample throughput by permitting safe stacking of fixed-angle rotors, so more samples can be processed per run.
• Manufacturer-designed spare ensures correct fit and compatibility with specified rotors, supporting safe operation.
• Cost‑effective option to expand concentrator capacity without purchasing additional full rotors or instruments.
