Z446 and Z446-K Universal High-Capacity Centrifuge Series: Maximum Capacity, Precision, and Versatility

The Z446 and Z446-K centrifuge models are built to handle high-capacity workloads, accommodating up to 4 x 750 ml tubes, making them the largest benchtop models in the Hermle-Benchmark range. The Z446-K model includes advanced CFC-free refrigeration for precise temperature control, ideal for sensitive applications. These centrifuges feature a robust swing-out rotor that withstands centrifugal forces up to 4,000 x g, supporting heavy loads with stability and precision.

Key Features:

• User-Friendly Interface: The Z446 series is equipped with an intuitive, touch-operated control panel, featuring a large LCD display. Users can easily program and store up to 99 runs with adjustable speed and RCF in increments of 10, providing precise control over each run.
• Advanced Safety Features: With RFID-based rotor identification for overspeed protection, active imbalance detection, and a motor-driven lid lock, the Z446 series ensures safe and reliable operation. An audible signal alerts users at the end of each run.
• High-Speed, Low-Noise Operation: These centrifuges achieve speeds up to 16,000 rpm with an RCF of 26,238 x g while maintaining noise levels below 65 dBA, providing a quieter environment for laboratory staff.
• Temperature Control (Z446-K): The Z446-K model features temperature control between -20°C and 40°C, with pre-cooling and standstill cooling capabilities. This ensures temperature-sensitive samples remain stable throughout the centrifugation process.
• Wide Range of Rotors and Accessories: The Z446 series supports a broad selection of rotors, including swing-out and angle rotors, with options for various tube sizes, microplates, and specialized applications. Accessories such as hermetically sealable lids and stacking adapters for microplates enhance the centrifuge’s versatility and functionality.
