Eppendorf 5425 R Refrigerated Centrifuge

Eppendorf 5425 R Refrigerated Centrifuge

Enhance your lab's sample processing with this used Eppendorf Centrifuge 5425 R, a premium refrigerated microcentrifuge featuring two aerosol-tight rotors.

The Eppendorf 5425 R is renowned for its whisper-quiet operation, fast cooling capabilities, and ability to maintain a constant 4°C even at maximum speeds. Designed to protect your temperature-sensitive samples, this unit features an intuitive digital display and push-button controls for easy parameter adjustments. This specific package offers exceptional versatility, coming fully equipped with two aerosol-tight rotors: the FA-24x2 for standard 1.5/2.0 mL tubes, and the FA-10x5 for larger 5.0 mL tubes.

Benefits & Features
- Aerosol-Tight QuickLock® Lids: Both rotors use QuickLock lids that lock securely with just a quarter-turn, saving time and reducing repetitive wrist strain. They are certified aerosol-tight for safe handling of hazardous or infectious samples.
- Advanced Refrigeration System: Features fast pre-cooling (~8 minutes) and vibration-reducing compressor technology to protect sensitive RNA, DNA, protein, and live-cell samples.
- Automatic Lid Opening: The lid automatically pops open at the end of a run to prevent sample warming and allow immediate access.
- OptiBowl® Design: Engineered for quiet operation even when run without a rotor lid.
- Soft-Touch One-Finger Closure: Ergonomic lid closing does not require heavy pushing or slamming.
- Short-Spin Function: Dedicated short-run key operates without needing to be held down continuously.
