Eppendorf WASHER (A) 5720411431

This appears to be an Eppendorf spare-part described generically as a "washer": a small mechanical sealing/spacing component used inside Eppendorf instruments. Manufacturer and authorized distributor listings show Eppendorf washers intended for rotor lids, clevis ends, pipette assemblies and housing fixtures, where they serve as seals or spacing/fastening elements. I was unable to locate a manufacturer-supported product page that exactly matches part number 5720411431; similar Eppendorf washer parts are listed under different internal part numbers (for example 022366823, 022662848).

Key Features:
