Laura’s Notebook: Weekend Updage with L. Spencer

Ups and downs this weekend!

Friday, 10:00am: asked PSRF to, in preparation for them lowering the heated line to 14degC, close the ambient line and turn off the mixing valve. I was alerted that they weren’t reducing T until Monday, so I thus directed them to instead, simply increase the mixing valve set point to 16degC (to maintain 18degC in culture tanks over the weekend). They kindly obliged, however an error was made with re-opening the ambient line (likely due to a broken valve handle, which makes it difficult to know whether the line is open, closed, or somewhere in-between).
