2 thiele tubes, capillary tubes, and shitload (~40) of those small amber storage bottles.
Thiele tubes and capillary bought from Nashinglass on ebay - I have to admit that the package was very well packed and secured

Is that 25, 50 or 100ml bottles?
That was a good price for 40 of those bottles.
That type is very good, autoclavable, can handle up to 140°C and holds most chemicals including acids like HCL.
They usually are little more expensive compared to other flasks.

Each is 100ml. The price was a bit surprising so I've made a small order first and after checking if everything is all right I ordered rest of them.
I was looking for this type and volume - it is ideal for my small scale experiments purposes.

I received some items from Laboy in China today, and I can say that it is fairly high quality glassware. Recommended from that aspect.
The internal aspect of order was well packed, and the exception is that they utilise incredibly flimsy cardboard for their outer packing, so buyer
beware if they are looking at purchasing some of the more delicate pieces from this place. No pieces were broken, but I don't know how.

I picked up an auger funnel, a backup 90mm 1L pore plate funnel (which is very high quality and rings like a bell), and some microscale odds and ends.
I don't actually need a new pore plate funnel, but my current one is one of my most heavily used pieces of glassware, and I don't want to have to wait
for months if I break it.

Not only have I never seen a pressure equalised auger funnel,
I never knew that they existed.
Please video the use of it.

I'll see what I can do. I don't actually have a purpose for it yet, but I'm sure I'll come up with one.

Distillation head for taking off reflux at desired ratio, received just today. 1 good supplier was able to obtain it for me, it was freshly made in
lab glass factory. 29/32 ground glass joints for attaching flasks and 14/23 for thermometer (dimensions used widely in my country).

That is a nice one. Out of curiosity - how much cost such a piece of glassware made on demand?

Hi outer_limits, the reseller asked for 8500 CZK which is approx 320 EUR. If I had contacts directly in glassware factory the price would be lower,
but I was really very happy that this reseller was able to obtain this rare piece of glass for me. He has been waiting for 3 months using an official
way without any sign of result, so then he asked directly the glass worker (good old contact) then he got the glass immediately. I would pay even
more, glass is always much more valuable than money  I believe that the most
difficult part in creating the piece was to create the loop. Connecting 2 ends of glass to create 1 connection is not so difficult, but creating 2
connections simultaneously (connecting 4 ends) is a masterpiece (I cannot imagine how to do it using only 2 hands, perhaps it required 2 workers to do
it synchronously).

The glassware I ordered from Aliexpress arrived a few days ago. Deschem's famous foam coffin works like a charm every time. Also ordered a few glass
beakers and graduated cylinders to start off my home chemistry glassware set.
 
Collected Elements:
C Al Ti Fe Ni Cu Zn Ag I Gd Au
Current Reagents on hand (Excluding common household reagents):
NaOH 10 M HCl 29% H2O2 MgSO4 CaCl2
Current Organic compounds on hand:
Acetone Toluene Xylene Isopropanol Methanol
Successfully Synthesized Compounds:
CuCl2 CuO Cu2O MgCl2 Mg(OH)2 Na2CO3
Attempted Syntheses:
Sodium Aluminate (precise formula varies) - Wasn't white as expected, was tan, impurities?
FeCl3 and FeCl2-Color was right but smelled horrible when it should be odorless
Acetic acid from vinegar: No Phase separation occured when salting out

Reading this I remember using following setup for reflux with items I had on hand:
- Packed column with raschigs
- Claisen head with thermometer on straight end and reflux condenser on bend
- Take-off valve with ground joints
With this I had total control of reflux, the condensate pooled in the takeoff valve and rest poured back to the column.
This could also be done with clevenger or dean-stark, especially with the smaller volume ones which a smaller cuts could be made.

Most recent deschem order. The foam sarcophagus worked well, as always
My old condenser column broke and I needed more round bottom flasks, so I decided to get a whole distillation apparatus, as it was cheaper than a
Liebig condenser and two flasks. Plus I got some 500ml beakers, because I didn't have anything over 350ml

I was unable to fractionate some of my small-scales synthesis with usual full-scale separate Vigreux column and Claisen head. Feeling of unfinished
jobs is devastational - my fridge contains several bottles of crude, not purified products. So, today eventually I've got this.

OK so it's nothing big, but the number of times I've decided I'm going to try extracting limonene only to remember that my only stillhead is my
vigreux is getting a bit silly so I'm glad this showed up.

Their website looks nice, where are they located? Their prices look like they sell Chinese glass with a markup. Do you know if they have their own
warehouse or are they drop shipping?

Anschütz-Thiele receiver/fraction cutter
I just got an Anschütz-Thiele receiver, which is the german version of the Perkin triangle. I've been trying to find one for some time now since they
cost an arm when new. Thankfully, ebay exists and an opportunity finally presented itself
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!
