After initially pouring 9:1 H2SO4:H2O2 bath, self heats to around 85 C, then steadily drops down to 70 even with the heater turned on.

Message-ID: I got a call from work control this evening at 6:30 p.m. about a Lab Leak Detector alarm. The TraceTek is showing a reading of 14 that places in in fingerwall 2 behind wbgen2. Sure enough, there is liquid on the floor (roughly 100-300 ml). I didn't check the pH of it. The only source of dripping that I can see is on DI water valve number 3 underneath the bench on the shelf on the right. That leakage rate, however, doesn't seem high enough to explain everything. Thanks, John
