Start off the day making a basic prototype? Sure. Why not?

Not only did I get complimented on my dress, I also got complimented on my veins this a.m. 🤣🤣 #labwork
Spent all afternoon making a super detailed plan for our Synchrotron experiment, which is great, except you just know the plan will deviate almost immediately! I can't imagine the chaos if you didn't go in with some kind of a plan though...
Heute habe ich mal eine nicht ganz kleine Schuhkiste, vollgestopft mit alten Bildern aller Formate und Negativen aus Jahrzehnten, ausgeräumt. Lose Albumfotos, alte Zeitungsabzüge, auch ein paar meiner Prints aus den ersten Labortagen in SW und 4C. Das alles will noch genau sortiert und gescannt werden. Nicht ganz wenig Arbeit.
Hier ein Barytprint aus den frühen 80ern, den ich noch immer vorzeigbar finde.

Hier mal eine der wenigen (Pseudo-)Solarisationen, die ich gemacht habe.

I've said this a few times now, but, pending disaster, today is my last day of labwork for this postdoc! I've got 4 mm of sample to mill (40 samples!). This speleothem grew during the early Holocene before stopping, and starting again in the 1930s. I'm very excited to see the stable isotope data approaching this hiatus!
The listening entertainment for the day is the Hobbit, as read by Andy Serkis. Libraries are the best 💚
I take bets if this abomination works in a Sysmex blood analyser. The normal racks don't give enough clearance for a type of test tubes, so...

First day working in the lab as crippled. Super frustrating and despiriting.. partially because I had to evacuate the building urgently using stirs… but I made it through 💪💪💪 #AcademicChatter #labwork #crippled
Re: last week's problem with the sonicator heating up.
Another lab had a recirculating chiller that they had never used and are willing to let me borrow it and fill it with water.
I only ended up with significant amounts of water where water shouldn't be twice while getting it going!
*Meanwhile in R&D "Hmm....this should work well."*
Commission I got from Foxenawolf of my Overlord minion having decided to get something heated up using some cooking tools.

Species of the rove beetles remotely-related genus Ptomaphagus (Staphylinioidea Leiodidae) are everywhere in gardens as well as in forests. This genus is easily identified. Their pronotum and elytra are both decorated with an unusual wavy pattern of transverse ridges. This one is a female from my forest floor (23.-V-2019). Alas, identifying females with certainty is tricky.
Dermestidae beetles taste for ravaging libraries, museums and wardrobes made them quite unpopular.
At the origin, they lived unnoticed in nature. This Dermestes undulatus Brahm was observed under my forest cover on 1. October 2019
Its antennae end into a 4 segmented club, made out of segments 8 to 11. But 8 is so tiny and well hidden under 9, that its existence is indicated by only a few bristles.
When you're multiplexing reactions and 5/6 work, but you have to do aqueous work-ups on all of them (including 6 to recover starting material) :blobHelp:
I put serious thought into whether the system would work with SPE before deciding that it seemed unlikely (and most likely give me something I had to do an aqueous work-up on anyway, just on a larger volume).
Got in my head about how much pressure I was exerting while cutting TLC plates and managed to botch some. Maybe a 1.5% loss of usable plates (~4/260), but I'm usually at 0% loss.
*sigh*
Going to be one of those days isn't it?
I'm always sort of amused with myself when I feel the need to leave a caution sign on the hood.
Current sign:
Caution
Hot plate is very hot & pressure vessel is in use.
I wouldn't usually bother for this sort of set-up, but it's at 150C and I plan to leave it all weekend. And one of the reagents boils at 70C. I 100% don't want anyone thinking they can borrow something in the hood without being careful.
Anyone have experience with large (96 well plate or 50 mL tube) homogenizers?
Biospec (my first choice, ~ $6,000) can't do what I want (longer than 5 minute runs) and the other options are *far* more expensive (the Benchmark BeadBlaster is ~ $10,000 unless the academic discount is significant...).
When it's 6PM on a Friday and you realize the major compound isolated was not only not the desired product (already knew that from TLC), but seems to be a weird hybrid of the substrate and the reagent by NMR (as in looks like one compound by integration, but chemically that doesn't make sense). 🙃
Also, not helping figure out why I'm getting 15-20% yields at best when the literature reports are ~80%. :meowTableFlip:
What I was not anticipating today: setting up 2 reactions only to walk over to the instrument and find that something had gone wrong. And then watching a reagent decompose while frantically dissolving samples in a not ideal solvent to transfer tubes so I could use a another (not as efficient) piece of equipment.
Hopefully at least the starting material (2 steps from commercial) can be recovered if these fail. Though the decomposing reagent isn't cheap.
sometimes things go wrong..
