I jsut ordered 20 grams of 2,2-bipyridyl. It is a nice coordinating agent and I intend to use this for experiments with ruthenium. Ru(bypy) complexes seem to have very interesting optical properties and I would like to see this into action myself.

Of course it is Rx, but the other claims are bullshit.

no chemical order. but i finally got some proper soft silicone hose, so I don't risk breaking my hose adapters whenever I pull it off.
4mx8mmID and 4mx10mmID set me back 43EUR! big bad ripoff!

Ugh... I can't tell you how much I long for soft rubber hoses. The PE (I believe) hoses most hardware stores carry are absolute shit. If they're not the perfect diameter they won't seal properly around the connections, and they're so DAMN stiff that they will tip over my condensers if they're not clamped to hell and back. I hate them! I got some PVC hoses that were only a little bit better, but still a huge improvement. I got a tip from one of my farmer friends to check out milk hoses. They're supposed to be natural rubber. So that's worth checking out for other people, too ;)

Once I went to a local store that deals primarily in hoses. They claim to be hose experts and they deliver a lot of speciality hoses to the industry. They had teflon lined, reinforced hoses of all imaginable diameters, hoses for foodstuffs, gasoline, acids, everything! But they didn't have any perfectly normal, ordinary rubber hoses. Not anything close to it :P

Is there a specific reason why melatonin is very watched? Here in Canada all pharmacies sell melatonin tablets off the shelf, same with natural food stores... No purchase limits or anything.

have you tried the hardware store? they will ususally carry natural latex tubing (usually 3/8") and its about 7 USD. one bad thing about is that it will rot quite readily if left out in the sun, or just outside in general....

hose

I suggest to buy from the one selling: 25FEET-xx/xx''-LATEX RUBBER TUBING-SURGICAL GRADE-NEW
25 ft would cost less than 20USD. and he has many different sizes.

Any idea why silicone would be so expensive?

PS:just to make you jealous, the rubber shop where I bought the hose also has lots of plastic beakers :)

I bid on an eBay auction in a knee-jerk fashion, and won a chemical I have no real use for... Lithium Lanthanum Titanate.

Any idea what I can do with it?

*Happy moment*

Being home by my dad's for the holidays, he dragged me off to a second-hand store. 'Nothing to see here,' I thought.

Until I saw a 5L buchner flask.

It's Pyrex brand, very good condition. No scrathes. The hose barb has previously been nicked and fire polished, that much is clear, but that's also the only thing.


And I got it for about 15€.

Nice, do you have any plans for experimentation with the metals (or are they just element samples?)?

Element samples, unfortunately. I don't have use for strontium or zirconium compounds at the moment...
Maybe in the future.

I am not sure for the best place for someone to get pyridine. I work at a university lab, which allows me to buy from alfa and sigma, (I got this one from alfa) which I understand is pretty hard to do if you don't work at a university

From eBay:

Reagent grade 48% HF in special UN-qualified bottle. Packaging and shipping is not cheap (appr. EUR 25), but with HF you'd better do things the right way. I want to use this for experiment with coordination chemistry.

What kind of test tubes can best be used for experiments with this? Can I use little plastic tubes as used in some cheap chemistry sets? Normally I consider those plastic test tubes like garbage, but they might actually be useful in experiments with HF. I do not want to spoil my glass with this. For fun, I'll sacrifice one test tube though by pouring in 2 ml or so of the 48% HF and filming this, until the liquid falls through the bottom of the test tube.
