CBG fishy smell


For me the problem is the fishy smell.  We recycled Propar for 3 years
before we got the CBG formalin/xylene recycler.  During that time we had
spilled over 4 liters of Propar.  What a mess.  We left the room and it was
cleaned up.  No one complained of a headache or nausea.  Then we got the CBG
recycler.  Five of us in the lab have complained and filled out forms
stating that we became nauseated or had a headache from the fishy odor of
the propar.  Now we cannot have the propar outside the hood.  The fishy
smell stays on the coverslipped slides and permeates the paraffin in the
blocks. I personally have a problem with them.  I have asked for an MSDS on
that fishy odor.  We also have treated the Propar with acetic acid and the
smell is less but not gone.  My question has been if you keep adding acetic
acid over time won't it build up and cause problems?  I've been having
problems with my GMS and it may or may not be related.

So far, I've heard nothing but good thing about the CBG formalin, alcohol,
xylene recycler. Can anyone give me any cons, beside the fishy smell?

Any suggestion is very helpful

Bruce, The fishy smell is not a problem. It's treatable. Just a minor

We demo-ed both the CBG recyclers and a formalin recycler from Creative
Solutions.  We purchased an alcohol/xylene recycler from CBG but purchased
formalin recycler from Creative Waste.  Both systems have their advantages
disadvantages, but we found the system from Creative Waste to be much more
simple to use and it just fit into our work routine better.  

The formalin system from Creative Waste is not a distillation system.  It
gravity and a system of filters to recycle the formalin.  You get the same
concentration and volume back as you put in.  You do not need to rebuffer
formalin.  We do not recycle really dirty formalin - we dispose of this
but you get waste with the CBG recycler, too.  I know this system sounds too
good to be true, but it has worked for us.  I also checked with other labs
have been using the system for several years and they are happy with it.  I
think it is worth checking out (and I am not affiliated with the company).

Their number is (888) 795-8300.

Works great for me with the richard allen blend reagent grade alc. We use
histoclear as our clearing agent and also get the fishy smell, more of a
burning smell for us though.
