Thermo Scientific* Sorvall Stratos Centrifuges are flexible, quick, compact, and are used for reliable separations. There are two models available: standard and continuous-flow. Both models feature refrigeration as well as innovative technologies that get rid of imbalances and ensure reliable results. Refrigeration system is free from CFC which is perfect for samples that are temperature-sensitive. A wide array of accessory biocontainment rotors improve the versatility of the instrument. Furthermore, patented spindle drive technology provides quick acceleration and braking and extends the life of the instrument. It also operates quietly. Improved safety is provided by its dual lid-locking feature. The system can detect the loss of sample during braking. It can also identify if the rotor is installed incorrectly in order to protect the drive. It identifies speeds that go over the limit and signals the maximum permitted rotor value. Sample preparation can be swiftly done through eye balancing of the tubes. The controls are also smart and intuitive. It is easy to navigate through the control panel.
