Eppendorf 7PC tube (B) 5720411045

The Eppendorf 7PC Tube (B) 5720411045 is a 7 mL polycarbonate centrifuge tube with a Type B snap cap for high-speed ultracentrifugation and sample handling.

Key Features:

• Nominal volume: 7 mL—provides moderate sample capacity for microcentrifugation applications
• Material: polycarbonate (PC)—offers high mechanical strength and optical clarity
• Dimensions: φ1.6 cm × 5.2 cm (diameter × height)—fits standard microcentrifuge rotor bores without adapters
• Maximum speed: 50,000 rpm—enables ultracentrifugation protocols requiring high rotational speeds
• Maximum relative centrifugal force: 253,000 × g—supports efficient separation of subcellular components
• Cap style: Type B snap cap—provides reliable sealing during high-speed centrifugation
• Packaging: 50 tubes per set—ensures sufficient quantity for high-throughput workflows

Advantages:

• 7 mL capacity accommodates routine sample processing and pelleting of moderate volumes
• Polycarbonate construction withstands high g-forces without cracking and allows clear visualization
• Compact φ1.6 cm × 5.2 cm footprint maximizes rotor capacity for multiple tubes
• Rated for 253,000 × g enables pelleting of organelles and macromolecules in ultracentrifugation
• Snap-cap design maintains seal integrity even at 50,000 rpm
• Pack of 50 reduces restocking frequency in busy labs
• Optical clarity of PC facilitates visual inspection of samples and pellet formation
• Consistent lot packaging supports reproducibility across experiments
