I know that the fumes can be toxic, but it is difficult to deal with completely. We have all of our spin coaters under a canopy exhaust that captures a lot of the fumes, but you can still smell it. Do others put the coaters in a fume hood? Perhaps use respirators? Or is it not that big of a concern if you capture most of it?<o:p></o:p></p><p>Thanks,<o:p></o:p></p><p>Nathanael<o:p></o:p></p><div><div><p class=MsoNormal><o:p> </o:p></p></div><div><div class=MsoNormal align=center style='text-align:center'><hr size=2 width="100%" align=center></div><p class=MsoNormal><strong><span style='font-family:"Arial",sans-serif'>Nathanael Sieb</span></strong><br><span style='font-size:10.0pt;font-family:"Arial",sans-serif'>Director of Operations and Administration</span><br><br><o:p></o:p></p><p class=headerfooter style='margin:0in;margin-bottom:.0001pt;line-height:110%'><span style='font-family:"Arial",sans-serif;color:#014B8A'>4D LABS, Simon Fraser University 8888 University Drive, Burnaby, B.C.
