500 mL, Deschem.

The quality does not appear to be extremely high in person, but I am sure they are quite functional. There's just enough room to fit small stirbars underneath the perforated gas outlets.

I am now the proud owner of a 500mL soxhlet and condenser. :)

Bit of a scary moment though. Package was not very secure. Just a cardboard box with a thin foam wrap. I opened carefully and heard the telltale clink and rattle of broken glass. Turns out everything was intact but there were fragments of glass tubing inside the soxhlet.

It is not very high quality. But I got it for under 20USD so I am not complaining. I bet it makes great coffee.

It was this one
http://www.ebay.com.au/itm/262767471069
But I paid a different price. From memory it was about $27AUD.

There are numerous sellers selling the same one so shop around a bit.

I've been thinking about getting one of those. I think elec-mall is the cheapest one willing to ship to me, but lovelyhome2015 has a better reputation. SacredLotus.com has a huge list of herbs used in traditional Chinese medicine. I bet it's possible to do some interesting chemistry with some of them.

If you catch Nurdrage's latest offering he doubles the yield of a Fischer esterification by swapping the reflux condenser for a soxhlet filled with 3A molecular sieves. That removes the water that is produced and pushes the equilibrium to the right. So it is not just extractions that they are useful for.

I figured that at that price it was a good addition to my glassware collection. It might not be used that often but handy to have around.

This is not technically glassware... but I got some tubing and a stirrer today. It is only a one-speed stirrer (although I suspect I can use a controller to change that), but it was dirt cheap, and unlike my other stirrer, it is in good working order.

That is a super cool idea. I think they are used a lot in natural products research but have limited application elsewhere... still, I definitely want one.

2. Beaker set 1000ml, 500ml 2: 250ml & 4: 100ml

3. Small morter and pestle

New mercury thermometer.

I am waiting on some thermometer wells so I can hopefully start using a thermocouple instead.

the tubing looks like the cheap latex tubing that comes with eBay Chinese kits
if it is, it's awful stuff;
too little water pressure and it collapses/kinks
a little more pressure and the tubing balloons !




When doing chemistry, don't forget basic physics.

It's very similar to that tubing but doesn't seem to collapse or kink as easily. I usually like to use PVC, but I needed something that would accommodate multiple hose barb sizes. While this tubing was expensive, I didn't see anything else that would work in my apparatus.

Got a couple more things to add to the Collection- a 300mm air condenser, A 300mm fractioning column and a 300ml porcelain crucible. Also had 300g of 3A molecular sieves arrive yesterday. Seems like 300 is the going trend lately.

The mercury thermometer? That came from the USA. It was expensive, and they are hard to ship. Several vendors in China sell similar ones for a fraction of the cost. I have not personally tried buying one of these.

There are several videos on YouTube of people using similar thermometer wells with thermocouples, so I am pretty sure it's possible to get that thermometer well to work with a thermocouple, but I haven't tried it yet. It has a 182 mm overall length with the thermometer well being perhaps 100 mm. I will say that it is too long for a distillation adapter but is the perfect size for a 500 mL flask. I think it would work well with a 1000 mL flask and possibly even a 2000 mL flask too, but it is a too small for a 3000 mL flask unless it is more than half full.

Just arrived!

1 L flatbottom 2 neck
350 mL #3 frit
thermometer well

all 24 40

Likely my last new ST buy for a while, though I'm always looking for cheap used.

I have a new (to me) 14/10 kit. It could use a few more adapters and flasks, and it could definitely stand a good cleaning, but it looks like the basics are here. I probably shouldn't have this thing so close to my toothbrush....

I also got this. The quality appears to be excellent.

Oddly enough the thing that stands out in your mini kit is the nice spatula. I guess I am not particularly attracted to 14/10 scale.
But that is a nice looking reflux condenser. Something that can cope with a decent heat transfer rate is good to have.
For example...

It's a Reacware condenser.

The spatula is all right. I have a slightly larger one that is round on one end and flat on the other. It's had limited exposure to some extremely corrosive and oxidizing environments and has never shown the slightest trace of rust, though it does have a visible passivating layer that makes it a little less shiny than its original milled finish, similar to the spatula above. I think they are 316 steel.
