Subject: [wbgen-ctb] TMAH and NH4OH bottles are mixed in the pass-through
	cabinet
Message-ID: <1664601967.1586187.1361207616528.JavaMail.root@stanford.edu>

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.


Best,

Sangmoo

Sangmoo:

Thanks for reporting this.  I believe that I've found and resolved the 
problem:  while the center row was labeled Ammonium Hydroxide inside the 
lab, there was no label on the outside of the passthrough cart where the 
staff fills is.  As a result, I expect that it was up to the discretion 
of the staff member doing the restocking.  I've now labeled that row 
Ammonium Hydroxide and made sure that there is only Ammonium Hydroxide 
in that row.

I did notice one other funny thing in the TMAH row:  there were three 
bottles of TMAH in that row each with only about a liter remaining in 
them.  Is there a good reason why folks are not using the remaining TMAH 
in a bottle before opening a new one?  I believe that is the practice 
and expectation elsewhere in the lab.

In any event, I now believe that you should reliably expect to see two 
rows of NH4OH in the pass through and only one of TMAH.

Thanks again,

John
