Refrigerated Centrifuge: SIGMA 3-18KS (max capacity 4 x 400 ml, max. RCF 30,070xg)
SIGMA 3-18KS Centrifuges, max capacity 4 x 400 mL
The Sigma 3‑18KS is the perfect choice for everyone who sets very high requirements for refrigerated benchtop centrifuges and is looking for a broad range of operating options. The centrifuge enables RCF values of more than 30,000 x g and is very convenient in use thanks to the patented Spincontrol S one-knob control and automatic lid lock. Combined with the extensive range of rotors and accessories, this all-purpose centrifuge sets standards for versatility and performance.
What makes the Sigma 3‑18KS all-purpose centrifuge so attractive
The Sigma 3‑18KS makes work processes in laboratory operation more efficient, safer and more convenient. The benchtop centrifuge has an extraordinary capacity with a maximum of 4 x 400 ml. The Sigma 3‑18KS is nicely complemented by a large selection of fixed-angle and swing-out rotors, buckets and adapters, including many biosafe configurations. Particularly thanks to the ability to use fixed-angle rotors with high RCF, the centrifuge covers a distinctly broader spectrum of applications compared to competitive units.
