Eppendorf CARBON RING 5720850976

Eppendorf offers O‑rings and sealing/closing rings as replacement seals for pipettes, centrifuge lids, bioreactors and other laboratory consumables; these parts provide leak‑tight sealing between mating components to preserve sample integrity and device performance. Manufacturer and authorized distributor listings show rings available in multiple materials (VMQ silicone, NBR, EPDM) and sizes for specific Eppendorf instruments. I could not locate a public Eppendorf product page that explicitly lists the exact part number 5720850976; available documentation therefore describes the family of Eppendorf sealing/O‑ring spare parts rather than that single SKU.

Key Features:

• Materials available: VMQ (vinyl methyl silicone), NBR (nitrile rubber) and EPDM as listed by Eppendorf/authorized distributors
• Intended use: replacement O‑rings/sealing rings for pipettes, centrifuge lids, bioreactors and related Eppendorf equipment
• Multiple sizes and inner/outer diameters offered to match specific models (device‑specific part numbers provided by manufacturer)
• Temperature resistance ranges shown for similar Eppendorf rings (example: VMQ approx. -60°C to +230°C; EPDM examples to roughly -40°F to +250°F on distributor listings)

Advantages:

• Provides a reliable, device‑specific leak‑tight seal to protect samples and maintain instrument performance
• Availability in multiple elastomer materials allows selection for chemical compatibility and temperature needs
• Manufacturer/authorized spare parts ensure fit and compatibility with designated Eppendorf models
• Simple, low‑cost preventive replacement part that helps avoid downtime and maintain calibration/performance
