A versatile and high-performance solution for your centrifugation needs: the Sigma 2-5
The Sigma 2-5 centrifuge is a compact laboratory device designed to meet the highest demands for processing small and medium sample volumes. Its intelligent design and high versatility make it the preferred choice for many research, medical biology and industrial analysis laboratories. Thanks to its brushless motor, the Sigma 2-5 ensures reliable operation while guaranteeing simplified maintenance and reduced operating costs.
The Sigma 2-5 has a wide range of interchangeable rotors that greatly increase its versatility. It can accommodate swing-out rotors suitable for large-capacity tubes up to 120 ml, as well as fixed-angle rotors for centrifuging up to 30 x 15 ml tubes in two rows. This flexibility makes it ideal for a wide range of applications, from cell sample preparation and clarification of bacterial suspensions to specific separation protocols in biochemistry and haematology.
Its impressive speed range from 100 rpm to 4,000 rpm allows both gentle centrifugation at low centrifugal force and fast separations requiring high acceleration. To ensure safety and ease of use, the centrifuge is equipped with a double safety lid lock, preventing accidental opening during operation. In addition, an imbalance detection device immediately stops the device in the event of a fault, protecting both the user and the equipment.
The Sigma 2-5's control panel is ergonomic and intuitive. It features a clear LCD display showing the rotation speed, remaining time and relative centrifugal force (RCF) in real time, an essential parameter for ensuring the reproducibility of experiments. The operating time can be programmed for up to 30 minutes or in continuous mode, offering great flexibility depending on the protocol requirements. The "Short run" function, which allows one-off centrifugation with a second-by-second cycle display, is particularly useful for quick adjustments or checks.
Among its many features, the Sigma 2-5 stands out for its "Soft start" and "Soft stop" modes, which ensure a gradual start and stop. These functions are essential for avoiding disruption of fragile sediments during critical centrifugation phases, thus guaranteeing the quality of separations. The low noise level of the device, limited to approximately 57 dB(A) even at maximum speed, contributes to a more pleasant and less stressful working environment for operators.
The stainless steel centrifuge chamber is designed to withstand chemicals and is easy to clean, an essential feature for maintaining a high level of hygiene and preventing cross-contamination between samples.
The Sigma 2-5 is the smart choice for laboratories looking for an efficient, versatile and durable device. Its robust design and wide range of accessories and rotor options make it an indispensable tool for both everyday use and more specialised applications.
