Schlenk techniques are very interesting. We have a couple of manifolds in my lab but we don't work with anything quite so sensitive so we mainly use them for high vacuum to get rid of trace solvents for NMR samples, or flame drying reaction flasks. I do appreciate the guide though, as I'm sure I will need to know how to perform these techniques some day.
11:45 I recommend to draw some inert gas after you measured the right amount of reagent to be sure that the cannula is empty if you do not want to see the purple-ish sparkles of tBuLi-solutions. And when pushing, hold the cannula fitting to the tight to the syringe or if available, use a Luer-lock-system. We had an accident in my lab some time ago where for what ever reason, it did not hold and someone sprayed some nBuLi-solutions.
Wow! This was an incredibly informative tutorial on advanced techniques of schlenk lines! Based on your experience with inert solvents, do you have any interest in making a video about degassing solvents for synthetic chemistry?
Thanks! I definitely plan on making more videos in the future! In the meantime, feel free to contact me directly if you want further information or illustrated guides/SOPs for specific techniques!
From my experience the simplest and safest method to effectively degase solvents is to bubble Argon or Nitrogen through the solvent with the aid of a needle for 15 to 30 min. This is good enough for probably more than 90% of organic chemistry. Even worked for me in reactions with a sensitive catalyst with very low loadings

Excelente video!!!! Muchas gracias!!!
Explanation is good

Hahaha thanks Worm!
could not post it before I started my project?! 😂😂 anyways keep the good job; you got a new subscriber
Does anyone know the software to draw the equipment the presenter uses?
Wow this was incredibly boring!👎
