Microscale Kits
I'm considering buying a micro scale kit at some point, and I'm wondering if anyone can comment on their experiences with them. I've found this one:
http://www.safetyemporium.com/ILPI_Site/WebPagesUS/detail.ht... It looks suspiciously identical, aside from the branding, to the Sigma Aldrich
branded ones the lab tech at university showed me the other day, right down to the packaging.
One thing I'm wondering in regard to using such a kit is how important it would be to have a highly accurate lab balance. I don't have one yet, and
likely won't for some time due to their cost, but am instead considering my options in purchasing a cheaper one. It's hard to know, even after reading
through a number of threads on the topic, if I'd be better served by getting a cheap one from ebay that purports a resolution of 0.001g, or to opt for
a 0.01g resolution, albeit likely to also be a cheap ebay purchase.

It does look like the Sigma kit. I have had 2 of the Sigma kits for several years. I believe Sigma does sell to resellers so it may very well be the
same kit.
Re the balance: you'll likely get varied opinions. I use a 0.01 balance with no substantial issues. I think I paid about $ 100 for it about 5 years
ago.

Thanks for the reply. I had actually wondered if Sigma just rebadged the glassware... Or do they make their own, or at least have an exclusive
supplier? Regardless, it seems a very nice kit.

The kit I believe is made by chemglass. I have one of their catalogues in a box under my bed lol... "Minum-ware" was one of their trademarks, but I
believe Sigma are resellers for them.

You can build by yourself a very effective and super cost-effective scale very cheaply. Look at rhodium archives...

this thread has nothing to do with measuring mass..microscale means carrying out reactions with microscopic amounts of reagents, like a few
mg (i.e. qualitatively but not preparatorily useful in most cases, but cheaper than normal scale).

haven't even heard about such a kits before(the smallest flasks are 25ml I think I have seen in reality and I should have somewhere), but I'll check
what wikipedia or Britannica says about the kits. Thanks for letting me know. 
This kit can be printed out in 3D fashion also, there is nothing difficult...but it's cheaper to buy of course the kit than printer, but in the long
run....
but if somebody needs a good 0.00001 scale for example, than look at Rhodium.
