Hermle Z446-K Refrigerated High Capacity Universal Centrifuge

The Z446-K is the refrigerated version of the Z446, designed to meet the needs of laboratories that require temperature control in their centrifugation processes. It offers all the features of the Z446 but includes a powerful refrigeration system capable of cooling samples from -20°C to 40°C. This feature is ideal for temperature-sensitive samples, providing more versatility in applications such as DNA, RNA, and protein work, where temperature control is crucial. The Z446-K also reaches a maximum speed of 16,000 rpm and an RCF of 26,328 xg, maintaining high performance while offering cooling capabilities.

The centrifuge’s construction includes a CFC-free refrigeration system that aligns with modern environmental standards. Like its counterpart, it features a large LCD display, easy-to-use control panel, and the capacity to store up to 99 programmable runs. Its enhanced safety features include an automatic rotor identification system with overspeed protection and active imbalance identification, ensuring secure and reliable operations.
