Eppendorf BLADE ASSY (R18C, R18C2) 5721850258

Manufacturer listings identify part number 5721850258 as the R18C batch unit (batch‑conversion assembly) for use with the Eppendorf R18C continuous‑flow rotor when installed in a CR22N centrifuge. The batch unit is the accessory required by the manufacturer to operate the R18C rotor in batch mode rather than continuous‑flow mode, enabling conventional closed‑tube or bottle centrifugation with that rotor.

Key Features:

• Manufacturer part number: 5721850258 — listed as R18C Batch unit for CR22N.
• Intended compatibility: R18C continuous‑flow rotor installed on CR22N centrifuge (batch configuration).
• Manufacturer listed quantity: 1 (unit supplied per material number entry).
• Associated rotor performance (R18C): maximum speed 18,000 rpm; maximum RCF 35,100 × g (context for rotor when used with accessory).

Advantages:

• Allows the R18C continuous‑flow rotor to be converted to a batch rotor per manufacturer instructions, enabling batch processing without a separate dedicated rotor.
• Ensures correct, manufacturer‑specified fit and configuration for safe operation of the R18C rotor in batch mode on CR22N instruments.
• Preserves rotor performance and compliance with the CR22N/R18C operating specifications by using the approved accessory.
