The 12156 fixed-angle rotor from Sigma Laboratory Centrifuges: a high-performance, safe solution for demanding applications
The 12156 fixed-angle rotor is an essential component for laboratories requiring speed, reliability and performance in their centrifugation procedures. Designed to work with Sigma 3-16L and 3-16KL benchtop centrifuges, this rotor demonstrates the German engineering quality that characterises the Sigma Laboratory Centrifuges brand. Its capacity to hold 8 x 50 ml round-bottom tubes makes it perfectly suited to the needs of hospital, industrial, academic and biomedical research laboratories.
This rotor stands out in particular for its robust and precise design, which allows it to reach a maximum speed of 10,000 rpm, generating a maximum relative centrifugal force (RCF) of 10,733 x g. This separation power guarantees fast and reliable results, even for the most complex samples. The 12156 rotor is made from high-quality, corrosion-resistant materials that are perfectly suited to the mechanical and thermal stresses of high-speed centrifugation.
Its fixed angle of 25° allows for efficient sedimentation of samples while minimising stress on the tube walls. This is particularly useful for preserving the integrity of delicate or sensitive samples. The rotor comes with a hermetically sealed aluminium lid (ref. 17840), ensuring increased safety by preventing leaks or cross-contamination during the centrifugation cycle.
In addition to its mechanical performance, the 12156 rotor fits perfectly into modern workflows. It is compatible with several types of tubes from 15 ml to 50 ml, including those made of polypropylene, polycarbonate and other high-strength plastics. Adapters are available to ensure a perfect fit for the tubes, increasing the versatility of the device while maintaining balance and safety during cycles.
This model is ideal for protocols requiring the separation of cells, DNA, plasma or fine particles. Its ergonomic design makes it easy to install and remove the rotor, reducing the risk of injury to the operator while optimising process efficiency. In addition, the rotor is fully compatible with the integrated safety features of Sigma centrifuges, including automatic rotor identification and motorised lid locking.
The durability of this rotor is enhanced by its ability to withstand aggressive chemicals, thanks in particular to the option of adding a Cleanroom coating. This special treatment, available on request, provides additional protection against corrosive products while facilitating cleaning and maintenance of the equipment.
The 12156 fixed-angle rotor is a reliable and high-performance choice for any organisation that values quality, precision and safety in its centrifugation operations. It embodies Sigma Laboratory Centrifuges' commitment to innovation, reliability and longevity in laboratory equipment.
