• Wide temperature range -20°C to 40°C with PID temperature control and ±1°C accuracy
• Speeds up to 21,000 rpm and maximum RCF up to 31,554 × g
• Heavy-duty steel housing with impact-resistant coating and corrosion-resistant 304 stainless steel chamber
• High-strength aluminum alloy rotors with precision balancing; many rotors and adapters available
• Autoclavable rotors and buckets for contamination-free operation
• Safety features: imbalance detection with automatic shutdown, automatic lid locking, over-speed protection, controlled braking, emergency lid release
• Low noise operation (≤58 dB(A)) and energy-efficient, CFC-free refrigeration
• Up to 30 program memory settings, last-run recall, adjustable acceleration/deceleration (1–10 rates)

Applications

• Temperature-controlled separation of biological samples including DNA, RNA, proteins, and cells
• Clinical diagnostics and hospital workflows requiring high-capacity refrigerated centrifugation
• Pharmaceutical and biotechnology sample preparation under controlled thermal conditions
• Molecular biology and biochemical research with high-speed precision separation
