Thermo Scientific T-1250 fixed angle rotor: power, reliability and precision for scientific research
The Thermo Scientific T-1250 rotor is a state-of-the-art piece of equipment designed for the most demanding ultracentrifugation applications. Made from forged titanium, this rotor combines mechanical strength, excellent corrosion resistance and long-lasting performance. It is equipped with twelve tubular compartments inclined at a fixed angle of 24°, allowing efficient sample separation in a wide range of analytical protocols. This design optimises the distribution of centrifugal forces, reducing the risk of tube deformation and ensuring accurate sedimentation.
With a maximum speed of 50,000 rpm, the T-1250 is capable of generating a relative centrifugal force (RCF) of up to 301,032 x g. This performance significantly reduces sedimentation times while ensuring sample integrity. The rotor has a total nominal capacity of 420 ml, with each compartment holding up to 35 ml. This makes it particularly suitable for intermediate volumes, typical of applications in molecular biology, biochemistry or virus and macromolecule purification.
Safety is at the heart of the T-1250's design. Two O-rings ensure a hermetic seal, preventing any leakage of biological or chemical materials. An overspeed protection disc with black, reflective segments is positioned under the rotor, ensuring strict compliance with operating limits and preventing mechanical failure. In addition, a secure locking mechanism keeps the lid in place during the ultracentrifugation cycle.
To extend the service life of the rotor and ensure safe operation, regular maintenance is recommended. It is important to clean the rotor after each use with mild detergents, avoid exposure to incompatible chemicals, and always balance the loads before a cycle. The ability to monitor cycles via the supplied rotor log allows you to comply with recommendations for removal after 5,000 cycles of use for safety reasons.
With its robust design, high performance and specialised accessories, the T-1250 rotor is an indispensable tool in research laboratories that demand precision, reliability and safety in their ultracentrifugation protocols.
