Dear wetbench users
There should be two lines for NH4OH bottles and one for TMAH bottles in the pass-through cabinet.
However, right now, there are one line for NH4OH and two for TMAH.
which means that TMAH bottles are sitting in the line for NH4OH ones.
I think that the staff made mistake when he filled the pass-through cabinet.
So... please watch out and check whenever it is the right chemical bottle for you before any experiment.
