These centrifuges offer a flexible rotor program with a modular adapter system which can accommodate a high variety of tube lengths. Ergonomic access height gives comfortable rotor loading. Low noise level. Motorized lid lock. Reliable cooling at maximum speed*. Imbalance detector. Automatic rotor recognition logs rotor performance parameters and prevents these being exceeded. Optional user setting by speed, rcf or radius correction values. Values can be changed during centrifugation. Temperature setting from -9°C to +40°C*. Standby cooling*. Selectable programme memory for up to 34 individual user programmes. Short-spin function, speed can be preselected. Fast-cool function* for rapid cooling of the centrifuge chamber. 10 gentle acceleration and braking profiles for sensitive sample material. This centrifuges are in vitro diagnostic medical devices as defined by Directive 98/79 / EC of the European Parliament and of the Council of 27 October 1998.
