Benchtop Centrifuges

ROTINA 420

Versatile Benchtop Centrifugation: Designed for routine clinical, research, and industrial applications with capacity for 4 × 100 mL tubes and a variety of rotor options.
Powerful Separation Performance: Achieves speeds up to 4,000 rpm with a maximum RCF up to 3,798 × g, enabling efficient separation across a wide range of sample types.
Flexible Rotor System: Supports a range of interchangeable rotors and adapter kits for tubes, bottles, and specialty formats, adding workflow flexibility to meet diverse laboratory needs.
Intuitive Digital Controls: User‑friendly keypad and display with programmable run times, adjustable speed control, and impulse (short‑spin) function for straightforward operation.
Quiet, Durable Drive: Brushless motor and reinforced chamber ensure quiet operation (≤ 58 dB(A)) and long‑lasting performance with minimal maintenance.
Advanced Safety Features: Equipped with automatic rotor recognition, imbalance detection with automatic shut‑off, motorized lid lock with emergency release, and robust housing for reliable centrifugation.
Optional Refrigeration (420 R): The Rotina 420 R model adds refrigerated operation (+4 °C to +40 °C) to protect temperature‑sensitive samples during centrifugation.
