How did I destroy $3000 worth of medication?

My new mini refrigerator wasn’t cool enough so I turned the dial up….when I went to mix a new batch the sterile water was slushy and almost frozen, not a huge deal, unthaw it and put it back in….well I fell asleep on the couch for a few hours. No bueno, a few days without and I am getting all the aches and pains back again…
