Eppendorf SEAL ASSY 5720411349

Eppendorf Seal Tubes (catalog series 5720411xxx) are heat-sealable centrifuge tubes designed for high‑speed and ultracentrifugation applications. They can be heat‑welded shut with tube sealers for secure containment of infectious or pathogenic samples and—when used with Eppendorf space caps and xg Boost float spacers—are specified for very high g‑forces. Typical uses include safe transport and ultracentrifugation of biohazardous samples and applications requiring maximum RCF stability.

Key Features:

• Heat‑weldable closure for tube sealers (enables permanent sealing of samples).
• Typical packaging: 50 pieces per pack (packaging varies by tube size).
• Compatibility with Eppendorf space cap and xg Boost float spacers for maximal g‑force application.
• Maximum RCF: up to 1,050,000 × g depending on tube size (RCF varies by specific tube model).

Advantages:

• Allows permanent, heat‑sealed containment of infectious/pathogenic material to reduce contamination risk.
• Engineered to withstand very high centrifugal forces when used with space caps/float spacers, supporting ultracentrifugation workflows.
• Sold in laboratory-ready packs (typically 50 pcs), simplifying inventory and replacement for routine centrifugation use.
