Sigma 12154 Rotor: Precision and Performance for 2 ml Tubes
Designed to meet the rigorous requirements of modern laboratories, the Sigma 12154 fixed-angle rotor fits perfectly with the Sigma 3-16L and 3-16KL benchtop centrifuges. This rotor is specially designed to hold up to 24 2 ml tubes, offering ideal capacity for daily centrifugation protocols in molecular biology, microbiology, clinical analysis and pharmaceutical preparations.
This model delivers a maximum speed of 15,300 rpm, enabling it to achieve an exceptional centrifugal force factor (FCR) of 21,460 x g. Thanks to a 45° angle, the orientation of the tubes promotes efficient separation of components while limiting mechanical stress on sensitive samples. This configuration ensures rapid and homogeneous sedimentation, which is essential in high-precision analytical processes.
The 12154 rotor is compatible with a wide variety of laboratory tubes, including polypropylene (PP), polyethylene (PE) and even paediatric tubes. For each type of tube, Sigma offers dedicated adapters (such as references 13021, 13000, 13002 or 13074), ensuring a secure and stable hold throughout the centrifugation process. The diversity of materials supported allows users to work with a wide range of samples, whether biological, chemical or environmental.
In terms of safety and ergonomics, the rotor is compatible with an aluminium lid that closes tightly to prevent leaks or cross-contamination. This lid also ensures optimal thermal resistance at full speed, with a minimum temperature of less than 4°C under operating conditions, making it compatible with the cooling requirements of the Sigma 3-16KL refrigerated version.
The entire structure is designed for easy cleaning and corrosion resistance, ensuring a long service life even in intensive working environments.
The Sigma 12154 rotor therefore stands out for its high performance, reliability and compatibility with a wide range of samples and applications. It is the optimal choice for users looking for an efficient and reliable centrifugation tool in research, teaching or hospital laboratories.
