Chemistry sets
« on: November 07, 2005, 10:17:17 PM »
I was wondering if anyone knows of good chemistry sets.  I never got one when I was little.  :'(  I really want to practice my chemistry with hands on stuff.  I am a visual learner.

Chemistry sets these days suck ass, I have had a couple, the best you get is a few tiny bottles of easily obtainable things such as copper sulfate, sodium carbonate etc.

Best thing I ever got was a bottle of phenolpthalein indicator, which I occasionally use, but even then its OTC.

A few years ago you might have got nitric acid, sulfur, hell, even a few oxidising agents like permanganate, chlorates etc, or metal powders (cough cough flashpowder cough cough ;D)

But nope, I have never even got any useful solvents in a chemistry set, its all plastic test tubes and useless shite.

As for chemicals, ebay is your friend, and when you get seriously into the hobby side of things, you make most of your own chemicals.

Hey thanks for the response.  That will save me some money.  Should I just buy stuff like beakers, Ernmeyler Flask, and chemicals as needed.  And as I am able to use them.

I am curious.
What is wrong with this chemistry set?

You could almost certainly buy several  hundredfold the amounts of those chemicals, AND some decent glassware for the price they want for that set off ebay.

Chemistry sets are typically aimed at young kids, and paid for by rich parents, who don't realise that for their money they could put together a FAR superior set of their own.

Stuff like erlenmayer flasks, RBFs, and a basic set of distillation glassware can usually be got for pretty cheap online, from ebay and the likes.

As for chemicals, same, ebay is good, and there are loads of other sources for things, if you get inventive as to sourcing, and for the things you cant buy, you can usually synthesize them youself :)

I am going to try to critically analyze this question and see if there is a different answer than posted above. I have copied below the contents of the link I posted previously for those who are link challenged. Also note that I do not have direct experience with the chemistry kit mentioned or have anything to gain by recommending it .My analysis may not apply to someone living outside the USA.

It is unclear to me from previous post why this kit was not acceptable to previous persons posting here. I will guess that there are two possibilities. One – you can get a better deal by purchasing the components separately. Two – the components are not worthy of what a kit should have to be beneficial.

Analysis of Reason One -
Let us say (rashly) that the kit cost $160USD when you include shipping and handling. Now, if we take all the components and sum up the cost of procuring them, I intuitively estimate that the cost would be greater. Also, we would have to factor in the convenience of buying all at once rather than piecemeal shopping.

Analysis of Reason Two –
If we assume that the manual provided is reasonably good and the description of kit (below) is accurate, the kit appears to be fun to do and educational. Granted, it would be nice to have other equipment, but that would be costly. I can not believe that a distillation apparatus are inexpensive. This kit is intended to do stuff at the test tube level, but you can do lots of good stuff at that level.

Conclusion –

The previously stated opinion that kits are generally not a worthwhile purchase does not apply to this kit.

Caveats –
I have assumed from the picture of the kit that it is not junky.
I have assumed the manual is reasonably good based on the description.
I assume the company providing this product is reputable.

Have a look for the C3000 instead of the C2000. It contains much more chemicals and more glassware. I purchased that one off eBay for EUR 108 (that's appr. US $130). I do not totally agree with limpet chicken. The C3000 is a nice chemistry set, which is a good basis to start with. Of course, it does not allow you to do all kinds of synths, but it does allow you to do many nice experments. Especially if you add chemicals yourself and a few other glassware items, then you can do MANY MANY experiments, also the more exotic (and sometimes dangerous) ones.

That price you mention is quite high. I think I pay a much lower price, because I purchased it directly in Germany (Kosmos C3000 is a german product) with german manuals and so on. Over here in the Netherlands, it is easy to obtain material from Germany and for you it has to be shipped overseas and with all those freaky hazmat regulations the price quickly rises.

My experiences with the box are good. The only disadvantage is its plastic pipette (I like a glass one much better) and some of the chems are only added at low quantities, while others are present in double amounts. But as I stated before, if you add your own chems and some additional simple glassware, then you have an ideal setup for many nice experiments.
