<p class="MsoNormal"><span style="font-size:11.0pt">-Do not disassemble the distillation apparatus into more than 4 pieces (bucket with pump, heating mantle with distillation head, condenser with tubing, and receiving flask with vacuum take off). See the SOP
for more info. The goal is to minimize how much gets taken apart so that it’s easier to put it back together again. Tubs should not be necessary, as everything can stay clamped to its ring stand.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">-Connections should be complete. There was a setup this afternoon on which the ground glass joints were not fully inserted into each other.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">-Ideally, the pump and heating mantle should be plugged in and turned on about 5-10 minutes before the lab session starts.<o:p></o:p></span></p>
