No Documents
The Beckman J2-MI Centrifuge is a refrigerated floor-model system designed for general laboratory use.
Engineered to protect both sample and rotor, the J2-MI centrifuge offers automatic rotor deceleration in situations where abnormalities are detected. An alert message will be displayed to signal the condition. This allows the user to diagnose the problem and restart the run.
Other notable features of the Beckman J2-MI refrigerated centrifuge include reliable touch switches, 10 program memories, automatic temperature control, and automatic maximum speed limits.
