Perfect for small labs, classrooms, or home science enthusiasts, this CALU LUKY benchtop centrifuge is a compact and affordable workhorse. It holds up to six 20ml tubes (tubes included) and spins them at a maximum speed of 4000 RPM, generating a relative centrifugal force of 1790 x g. That's great for low-speed separations like pelleting cells, separating plasma from blood, or other basic lab protocols. The controls are simple: a dial for speed (0-4000 RPM) and a timer that can be set from 0 to 60 minutes or set to run continuously. It runs on standard 110V power, is relatively quiet, and has a small footprint for any tabletop. It's ideal for educational settings, small medical or research labs, or hobbyists working with biology or chemistry samples. Just make sure your samples are balanced! Always follow safe centrifuge practices. This is a basic, no-frills machine that gets the job done for a wide range of low-speed applications.
