[Histonet] xylene in an unventilated area

[Gervaip <@t> aol.com]

I just recently did a lot of research into the different hoods.  I  decided 
the down draft was not going to work for us since we like to place  
absorbant towels down to catch the xylene while coverslipping.  I decided  to 
purchase one that a high CFM (Air flow rate), low decibles and a monitor on  the 
filter to let one know when the filter was saturated and needed to be  
changed.  And I wanted the sash that comes down in front of your face to be  
glass, so that we could clean it periodically with xylene to get splashes of  
mounting media off.  For the money PurAir was very good...   body  was plastic 
and the clear part that is lowered while in use was plastic.   It had good 
CFM, good decible level and a monitor for filter  saturation.    The 
LabConco is stainless steel and glass, with  good CFM, decible level and a monitor 
for filter saturation.  
The problem with the little Shandon is that the CFM is about  30 at max 
when the sash is lowered.  Newer ones, such as the PurAir  and Labconco have 
about 120+ CFM.  And the Shandon has no monitor for  filter saturation.  The 
PurAir had the footprint needed for cytology, which  is very small in my 
area.  
There is another company that was good, but my brain cells cannot recall  
the info.  If anyone wants more info, please e-mail me.

Try to get a  fume hood; it could be one movible over the counter, but 
needs to have a good  charcoal filter.

Hello   all.   Cytology was told that the xylene substitute the= y  were
using  for their Surepath paps was causing  staining/artifact issues.&   
nbsp;  They   want  to  switch to using xylene in their area, but it  is
unventil=  ated.  Because of various  reasons, their process can not be
moved.&nbs= p; They  are asking me for advice about what to do for  fume
control.  I= was wondering if a good downdraft  unit would be enough to
handle  the   xylen=  e  fumes.   They will have maybe 400 mL of  xylene
uncovered  while  covers= lipping their  paps.  Does anyone else have a
similar   set  up?  The= y share their area with micro and core lab  and
others  are  complaining about= fumes even  though they have borrowed a
mini-hood from us.   Badge resu= lts are still pending.
