ynaan is one of Yee Chen's eBay aliases. They tried to pull the same 50% refund crap with me on my receiver despite stating that they pay return shipping on their auctions. There is no rational reason to agree to a 50% refund from them; just have eBay collect the entire amount for you.

Deschem's packaging is the best. I have never gotten a broken item from them either. The quality of their items varies; some are very high quality and some are not, but their items seem to be always functional.

Laboy is known for quality... I think they are better than Pyrex.

I need to replace my fritted buchner, I'm stuck using a ceramic one now without inbuilt vac takeoff, Accidentally knocked it and shattered it. Although the frit is intact at least, so I'll reuse it either with a ceramic funnel hacked onto a ground glass joint, build an enamelled funnel or use the frit for a salt bridge in an electrolytic cell of some kind.

Bought a fair bit of new stuff though:

A couple of lengths of fused quartz tubing, pressure-equalized addition funnel, 100-pack of melting point capillary tubes, 2x drying tubes,
and a spare soxhlet. Actually a matched set of soxhlet and allihn condenser for it, I already had a soxhlet, but needed to pick up a condenser since the joint size is larger than any of mine. Figured I may as well get the set, since it was no more than I'd expect to have paid for the allihn to use with the soxhlet I have already, and get a second soxhlet for essentially free, bought a powder addition funnel also, and a dreschel bottle.

Total cost? about £90 inc. shipping for the one or maybe two items that charged any.

Is this a powder addition funnel with an auger?

Dreschel bottles are pretty cool. I have two. Usually, I use one as a suckback trap and the other one for gassing, but I'd like to have at least four.

Oh and quartz tubes are awesome.

Six bucks at University Surplus!

Another $25 on a couple boxes of flasks and reagent bottles, too.

Now I gotta jigger a condenser...

I like the Klein bottle approach. i have not seen this configuration before.
Nice acquisition.

It's a pretty standard Soxhlet.

If you get an adapter for it, you can use it with a condenser that you already own.

That's the idea. Since you can get one of these, with a condenser, for not much, I'm looking for a good deal on an adapter, as well.

I got one from Nanshin rather inexpensively, and it works perfectly fine. Laboy makes bushings that look really nice, but I haven't tried them.

I have no idea if Dr. Bob would have one or not, but he has some good deals on lightly used name brand equipment.

I just bought a big 50 mL 3-neck flask in 14/10 with threaded joints and PTFE septa for my microscale setup. I also got a distillation adapter and a 25 mL flask.

I really need to find some long needles, preferably ones that will stand up to corrosives and aren't too expensive. I definitely don't want to buy expensive ones that won't stand up to corrosives.

Well I've no need to buy an adapter, since I already wanted the condenser, the fact that it was sold as a matched set with a soxhlet, for much the same price range that it'd have cost me for the condenser alone just means I essentially got a free second soxhlet as a bonus.

Something arrived for me today that I'd actually forgotten about, a mini-scale pear shaped flask (50ml I think although I'd have to check, with a sidearm, a central column with a female joint at the top and a sideways-oriented joint for taking a condenser, the column itself has a section of its length as a vigreaux column.), the pressure equalized addition funnel, and 100x capillary tubes for MP determination.

I got a 105 degree takeoff adapter for my 14/10 microscale kit. Now I can do a fractional distillation without a Hickman distillation head.

I also got a 25 mL flask (in 14/10) and the big, bad 50 mL 3-neck flask. Rawr.

I got my 1L filter funnel! Quality is so-so, with tiny bubbles visible at the joints, but I think it will function just fine.

Looks nice.

A useful warm-up exercise could be drain unblocker sulphuric acid (338oC max)
The brand that I used (Hexeal, amazon, uk) cleared up by just boiling,
but a small quantity of distilled azeotropic H2SO4 would be handy.
(boiling without condensing caused choking fog :(

It's not quite flawless (it has a tiny indentation that like a tool mark on top of the distillation arm) but it is free of bubbles and rings like a bell. I am sure it is quite functional, and I'm planning to distill some sulfuric acid with it in the near future. Aluminum bromide looks like fun too.

(Oh and I'm planning on giving away a similar flask to whoever wins the oxalyl chloride challenge.)

After more than two years of use, my beaker set had become quite badly scratched, and two of them were broken. Also, my 15 year-old 100 mL graduated cylinder cracked at the top, making it dangerous to use and prone to spills. It's been through literally hundreds of reactions, but it's time for it to retire. So I ordered a new beaker set and a new graduated cylinder.

Was this from eBay? I have been looking at one on there recently. A quartz distillation flask would be nice to have for destructive distillations, or other high-boiling liquids.

As a matter of fact, it was. They had some more listed for sale. If you message Elaine (their eBay salesperson), she'll probably list some more. Which reminds me, I've been meaning to order some ground quartz tubes....

My new (old) condenser arrived on Friday, sadly I was away for the weekend and I couldn't see it until today.

Chemglass.jpeg - 328kB Chemglass2.jpeg - 304kB

Chemglass dimroth condenser, I think 250mm but I'm not sure how they measure it. No scratches, chips, cracks, or any imperfections that I can see. It's also completely clean, zero residue. Not bad for $37:P.

I also got my first glass frit, which goes well with my new water aspirator!

Now off to the hardware store so I can connect my aspirator...

Cool stuff. If you have a Dimroth condenser, you hardly even need a Liebig.

Just had to replace my largest sep funnel, after some piece of shit (for the second time) trashed my project. Still, it'll be him thats paying for it, since I owe him some money, and now he just isn't going to get it, and god help him should he even think about whingeing.

Got a pair of vacuum adapters of the short kind, more or less a 24/40 (which most of my glassware is) stopper, leading to a stopcock and hose attachment last night. Plus, grabbed a liter each of MeCN and toluene while I was at it.

Bought a few flasks as well, the one I remember (might have been two, can't remember for sure) being a 2- or 3-neck 500ml RBF.

Plus the above. (no, the drying agent wasn't in the drying tube, of which I bought two) when it came, and the plastic hose and hose clamps were not attached to the glass U-tube either, it was me that attached the lengths of hose.
