  • dude,where is your lab gown?

  • Believe me, we did try a lab coat, but the studio lights were so intense that our instructor shone like a fluorescent bulb, ruining the whole frame. We tried *three* different shirts until we decided to go with this very unprofessional-looking shirt, which worked the best with the lights.

    I had no idea what the hell was going on.

  • so the impurities remain dissolved in the solvent? what type of organic solvent should we use if the compound we want is not water soluble and should be harmless if consumed?

  • What was the substance used in the video ?pliz

  • LOL for my recrystallization lab, started out with .46g, ended up with 0.04g. Worst part was I needed it for the next lab xD. I cannot express my hatred for ochem lol

  • Vacuum drying in a steam bath is the best way to crash out solids. Especially in a sibata.

  • Thank you it was really useful

  • I think you have something wrong at the end of the video. You have written "(...) the solvent may recrystallize (...)", but it is not the solvent that recrystallizes.

    Kind regards,

    E.

  • @scivislab thats because of the black background you are using. Its all about quantum wave mechanics bro... its all about quantum wave mechanics.

  • Your videos are the most helpful I've found, thank you!!
