The Good
Basic microcentrifuge, can hold different rotors (sold separately) for different sized tubes
The Bad
1.5 mL rotor is only specific for 1.5 mL tubes, not super quiet, has control knob/dial instead of digital display
The Bottom Line
This is a good standard microcentrifuge that is fairly cheap. Control knobs are kind of outdated and the speed can only be set in RPM. 1.5 mL rotor will not hold other tubes of similar size, including 2mL tubes and certain spin columns (ours would not hold the Qiagen RNeasy mini columns).
