Eppendorf SPACER(B) 5721411344

The Eppendorf SPACER(B) 5721411344 is an OEM replacement spacer accessory used to provide defined spacing or to enable stacking/adaptation in compatible Eppendorf laboratory instruments. Manufacturer product descriptions for Eppendorf spacers include rotor spacers (used with Vacufuge concentrators to allow stacking of fixed‑angle rotors) and spacer bars for biological shakers such as the TTR‑210 (used to accommodate tube racks). Typical use cases are increasing sample throughput by stacking rotors and adapting shaker platforms or tube racks to fit the instrument.

Key Features:

• Function: OEM spacer intended for spacing/adaptation or stacking of components in Eppendorf equipment (spacer bar or rotor spacer function).
• Application examples: Manufacturer lists rotor spacers for Vacufuge concentrators and spacer bars for the TTR‑210 biological shaker.
• Capacity impact: Manufacturer notes that rotor spacers enable stacking of some fixed‑angle rotors, effectively increasing sample capacity (stacking can double capacity for compatible rotors).
• Compatibility examples: Manufacturer documentation references use with Vacufuge plus and fixed‑angle rotors (examples include rotors F‑45‑72‑8 and F‑45‑48‑11).
• Packaging/ordering: Supplied/sold as individual Eppendorf spare/accessory items.

Advantages:

• Increases sample throughput by permitting safe stacking of compatible rotors to run more tubes per run.
• OEM part ensures correct fit and operational safety when used with specified Eppendorf rotors or shaker accessories.
• Enables flexible use of different tube racks or rotor configurations by providing the required spacing or support.
• Simple spare/accessory solution—sold individually so users can add the spacer only where needed.
