Hermle Z446-K Refrigerated Centrifuge with Swing Out Rotor delivers high-capacity performance and advanced safety features in a compact benchtop design. With aircraft-grade premium alloy construction, this centrifuge supports up to 4 x 750ml, handling demanding workloads while maintaining stability under high centrifugal forces. The included swing-out rotor accommodates up to 28 x 50ml or 68 x 15ml tubes.
The intuitive control panel includes a backlit LCD screen that displays real-time rotor information and operational status. Automatic rotor recognition prevents overspeed by converting RPM to RCF, matching the capabilities of the installed rotor. Acceleration and deceleration rates are fully adjustable, along with customizable alarm tones. The unit stores frequently used programs for fast recall and repeatability.
Tool-assisted rotor exchange takes less than a minute using the included rotor wrench. Pre-cooling and a wide temperature range from -20°C to +40°C ensure optimal sample protection. Let us know the tubes you plan to use, and we can help you select the best rotors and accessories for your workflow.
