Sam LevineQuestion for people who maybe do fab and/or electronics work (or anyone else). Are your "desiccator cabinets" air tight in a similar way that chemical ones are? They get called by the same term and also marked as "static dissipative". By air tight I mean I can put in a color changing desiccant and it shouldn't change color for months at a minimum if I don't open the door. Pictures don't make it clear if there is a gasket that would give this sort of seal or not.<a href="https://neuromatch.social/tags/Chemistry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Chemistry</a> <a href="https://neuromatch.social/tags/ChemiVerse" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ChemiVerse</a>

Sam LevineDoes anyone have experience working with a vacuum/inert gas manifold that doesn't have an outlet for an oil bubbler on the inert gas side? Both vacuum & gas sides just have a single hose barb and a sealed end. It looks like the previous user might have just opened up one of the ports and connected it to a bubbler, but is there a better method? Is there some technique I'm not familiar with that uses this setup? Maybe splicing in the bubbler before the line (though that seems weird...it's usually at the end to force gas to keep flowing so you don't have any "dead" space)?It looks like it's one of these: <a href="https://chemglass.com/vacuum-manifolds-inert-gas-glass-stopcocks" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://chemglass.com/vacuum-manifolds-inert-gas-glass-stopcocks</a><a href="https://neuromatch.social/tags/Chemistry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Chemistry</a> <a href="https://neuromatch.social/tags/ChemiVerse" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ChemiVerse</a>

Sam LevineI have no idea how competitive this is (maybe they only get 10 applicants? maybe they get 10,000?) but it might be worth having grad students apply since it looks like the initial application is only a total of 375 words.

Sam LevineYesterday Me: cleaves Boc group to make a primary in methanolic HCl Also me: forgets that there is a ketone in the compoundToday: I looked at the TLC and went "uh oh". Clean-ish conversion to a single much higher Rf spot (I was thinking if I got imine formation it would just be a polymeric mess). So I drew some stuff in chemdraw and lo-and-behold it's possible to make a 15 member macrocycle if I draw an intra molecular imine bond. Dammit. Odds of my breaking that to rescue the 95 mg of material in here without also cleaving one of the multiple amide bonds doesn't look good (10 min with 2 M aqueous HCl at room temp certainly didn't do it). NMR is a bit messy, but the chemical shift for the 1H that might tell me what happened (I didn't put enough in the tube to resolve the 13C carbonyls, whoops) looks more like imine adjacent than amine adjacent.Might just have to put more sample in the NMR tube to prove I screwed up?<a href="https://neuromatch.social/tags/Chemistry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Chemistry</a> <a href="https://neuromatch.social/tags/ChemiVerse" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ChemiVerse</a>

Sam LevineOne of the best bits in the talk was him mentioning "oh this chiral pseudoephenamine gives better results than the pseudoephedrine and it's not a regulated compound".

Sam LevineAnyone with a lab balance for larger things (the type you usually weigh 100s of grams on) have a max weight recommendation?

Sam LevineYou know stuff is getting real on the moving front when the shelving I told my supervisor I never, ever wanted to have to take apart is coming out.I'm sort of inordinately proud of these. The dimensions of the foot wells where we wanted shelves were such that if you removed the back panel of the well you could put the rear posts behind the lower lip and the front posts just in front of the opening and maximize your shelf space.
