To All Today Physical Facilities will be shutting down all electricity to POTR, from 5:30pm to 9:30pm. So we will turn off all HPLC systems before 5:00 pm. If you plan on running samples, please complete it by 4:30 pm. We will turn on the HPLC system on Monday (3/21/2016). Also please unplug electricity from your computer and all important equipment from outlet before 5:00pm. Thanks HPLC Recharge Center
