Bio-Rad Profinia™ Protein Purification Instrument - Manual (Page 95)

Important: When the Profinia system is used in a cold environment, it is best to leave
instrument power on; the slight amount of heat generated helps control condensation. The
UV lamp automatically turns off one hour after the last separation run, and turns back on
when instrument operation resumes. If the instrument will be stored long term in a cold
environment, it is acceptable to turn the power off. When the instrument is removed from a
cold environment, the unit must be equilibrated to room temperature. This prevents
condensation from forming which could possibly be damaging to internal components.
