New Sigma 3-18KT Centrifuge Reaches up to 31 655 × g and Takes Over from the 3-18KS
The new Sigma 3-18KT refrigerated benchtop centrifuge reaches up to 31 655 × g with selected fixed-angle rotors and can hold samples at 4 °C at maximum speed with every rotor. It follows the Sigma 3-18KS, which goes out of production at the end of December 2026. We accept the last orders for the 3-18KS until 8 December 2026.

Choose the 3-18KT If Your Method Needs More Than 25 559 × g
Two models follow the 3-18KS: the 3-18KT and the 3-17KT. The 3-17KT reaches up to 25 559 × g, so if you run your samples above that force, the 3-18KT is your model.
What Changes Compared with the 3-18KS
The 3-18KT replaces the one-knob control with a touchscreen and lets you export run data to a USB stick. A new fixed-angle rotor, the FA-8x50-V, holds eight 50 mL conical tubes instead of six and reaches 11 828 × g.
