I put the corresponding solvent into the metal bins labeled (SG + DI) (simple green (30:1) and DI water), DI (DI water), and Iso (isopropanol) and placed all 3 bins in the sonicator at once. The bins fit nicely into it. There was no visible degradation to the bins after this procedure. I then emptied them.

I noticed the sonicator temperature rose as soon as I turned it on. Considering this rapid change, I think this is an error with the sensor.

I also cleaned the 50 mL and 1 L beaker with simple green and then DI water.

I think the chemistry room is ready to use!
