<p class="MsoNormal"><span style="font-family:"Buckeye Sans 2";color:#212121">The distillation apparatus needs to be unplugged when not in use. Ideally, the water pump and heating mantle should be plugged in and turned on about 10-15 minutes before the lab
session starts. The apparatus needs to be checked at least every 30 minutes by someone from the lab support window. Set a timer for 30 minutes to remind yourselves.

flask (still pot) properly. You must watch this video prior to the start of CPC.
</span><span style="font-family:"Buckeye Sans 2";color:red">Remember that both tubes (from the condenser and to the condenser) should be inside the bucket</span><span style="font-family:"Buckeye Sans 2";color:#212121">.</span></p>

<p class="MsoNormal"><span style="font-family:"Buckeye Sans 2";color:#212121">If you need to stop heating the flask for any reason, turn the heating mantle off and lower it away from the flask. This is why we set them up so high- it makes it easy to kill the
heat quickly.</span></p>
