Centrifuge: SIGMA 4-5KRL (max capacity 140 blood collection tubes / 16 microtiter plates, max. RCF 4,470xg)
SIGMA 4-5KRL Centrifuge, max capacity 140 blood collection tubes / 16 microtiter plates
The innovative Sigma 4‑5KRL is specifically designed for integration into laboratory automation systems (total lab automation). This refrigerated centrifuge is designed for robot loading and unloading, as well as control over the integrated serial interface. It is ideal for a very high volume of specimen tubes for clinical in vitro diagnostics (IVD) and for use with microtiter plates and custom tubes and flasks. Its compact construction facilitate easy integration into workflows, thereby making a significant contribution to higher efficiency in the lab.
What makes the Sigma 4‑5KRL robot centrifuge so attractive
The patented bucket lifting device is one of its unique features. This innovative bucket levelling function ensures that after each centrifugation run, the buckets return to a horizontally and vertically reproducible position at the loading/unloading location. This innovation decisively boosts process reliability.
The Sigma 4‑5KRL features impressively low process downtimes. For example, lid opening and closing takes less than 2 seconds, and the rotor indexing time is just 8 seconds. Combined with the innovative bucket levelling function for precise positioning of the buckets, this enables quick loading and unloading of the centrifuge, helping to boost throughput.
The low-profile centrifuge lid allows the Sigma 4‑5KRL to be placed directly beneath the work platform, enabling minimisation of the robot Z axis length.
The powerful drive of the Sigma 4‑5KRL ensures short braking and acceleration times of just 23 and 24 seconds, respectively. Smooth running allows reproducible centrifugation results to be achieved.
