High performance, low noise and high capacity

The main strength of the Sigma 4-5L centrifuge is its high throughput capacity, which is a key factor for hospital use. Other advantages of this laboratory centrifuge include high motor torque for fast acceleration, minimal temperature rise and low operating noise level.

The Sigma 4-5L combines unusually high performance with quiet operation. Automatic lid opening and one-button control make things even easier for users, and the stainless steel rotor chamber is especially easy to clean.


The extensive range of accessories is impressive. Along with tubes and flasks from 1.5 to 750 ml, it includes buckets to hold microtiter and deepwell plates. With RCF values up to 4,643 x g, the Sigma 4‑5L is also well suited to centrifuging gel tubes. The maximum capacity per run of blood collection tubes for clinical in vitro diagnostics (IVD) is outstanding. For instance, it can hold up to 144 blood collection tubes with 13 mm diameter or 100 blood collection tubes with 16 mm diameter from all known manufacturers. This means the Sigma 4‑5L offers up to 25% more capacity that comparable units in its class.

The Sigma 4‑5L is also available as refrigerated centrifuge and as an IVD model.
