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.
