This is actually a really useful piece of equipment: it allows the collection of many fractions during vacuum distillation without having to bring the whole apparatus back to atmospheric pressure. Normally you are limited to 3-4 fractions if you're using a cow receiver, but not with this!

That is gorgeous, Heptylene. Nice acquisition.

Heptylene congrat. Recently I managed to buy Anschütz-Thiele receiver too :)

here nicely explained how does it work:

If there is a heaven, it seems not to be materially based. Does chemistry exist there and if yes, how does it look like? Are there good souls well supplied with laboratory equipment, glass, chemicals and information?

Some GL45 reagent bottles. I really like these! Although they are not exactly cheap, they are of high quality. There are red cap versions, which have a PTFE liner. The PTFE lined ones are even more expensive. Do you think that the blue cap bottles will suffice for most situations? When would you prefer the red caps over the blue caps?

You cant see it but theres also a top shelf with a lot of tiny vial sized bottles. I actually got this little cupboard specifically for this so i think its a pretty good start.




I am a big fan of the old fashioned Apothecary bottles. Adrian ('Plasticraincoat1' or 'Adrian's Chemistry Laboratory' on youtube) has a lot of the old fashioned bottles in his lab

I was browsing online for gifts for other people, and then couldn't resist buying myself a couple cheap nickel crucibles from AliX. I'm hoping to hydrolyze piperine to the acid without a twelve-hour reflux (higher temp, ethylene glycol, KOH).

When storing something like bromine or low boiling stuff like ethyl ether or bromoethane

Here without looking for them I found these Anschutz-Thiele receivers with good price and various joints sizes:

I have been after some cheap SS 1/4" VCR hi vacuum/pressure gas fittings for some time. I finally won an auction on a job lot of used ones for £12.50. They arrived today. I did not win 55mm diameter vacuum valve that i also needed. That sold for more than £100.
