hey not trying to be a jerk, but every one doesn't have to open their own thread about each set of glassware... the topics can be stacked on the same
thread. there is currently an active thread (started this month even) still up on today's posts. that obviously means it's actively being used and
viewed. just because you are asking feedback on THIS set, doesn't mean you couldn't pop it right on in there and still get answers. be sure to read
the site guidelines about posting. not sure if this violates any rules per se, but it will more than likely get merged with others and that is work
for mods they don't really need to be putting in.
here are the posting guidelines
https://www.sciencemadness.org/whisper/viewthread.php?tid=19...
BTW welcome to science madness. it's a great site with lots of info so have fun, but lets keep it easy on the mod's as far as managing extra threads.
*** moderators: if this thread gets merged into an existing thread, feel free to delete this ***

I've spoken with a few people here who have parents with serious issues towards eBay, why is this? Terrible experiences?
Anyhow, it's hard to say if the hotplate is good and/or how long it will be good for. The absolute best is to try and find a used brand name plate
such as IKA, PMC, Corning to mention a few. I managed to get a nice digital corning for 230$, off eBay though...

If people have an issue with ebay it's because they've got burned. About half the used stuff I've gotten from ebay was junk. When they say "powers up"
that's about all it does.
Also my daughter bought and paid for a cello and never received it.

I have access to a great stove top hotplate, right in my lab, and a small hotplate as well.

Keep in mind that the temp display doesn't mean much unless you have a probe that adjusts the heat to reach a specific temp in your reaction vessel.

with corning: very well made and usually priced out of reach. you can even find RBF heating blocks for the Silicogex stirplates unlike corning. Check
what voltage it runs on though.

If there's going to be a lot of stirring and heating of say liter flasks, a mantle with built in stirrer is nifty. The jointed glassware maxim applies
to overhead stirring: totally worth it.

IME anything with a motor/rotates in a lab is either rarely brand new in a dusty box (this typically applies to ASTM-related glassware) or most
typically on it's last legs when it comes up for auction. Something nice tends to wind up in another lab somehow. Schools on ebay are the best bet.
It almost goes without saying that the ebay/paypal machine is the devil. It's worse for the sellers. Some of this burning is from ebay policies and
the complaint staff's various interpretations of them. I'm shut out by refusing to hand them open access to a bank account (health care is also going
this way if you've been to the hospital lately) or third credit card, after reaching ebay lifetime payment to just under the credit limit of the
cards.

I wouldn't be using 1L flasks much.
http://www.amazon.com/Scilogex-86143101-MS-H280-Pro-BlueSpin...
Here I found a not to overpriced scilogex hotplate.
http://www.amazon.com/Corning-Life-Sciences-Scholar-Plate/dp...
And here is a less advanced, but better priced corning one. What are your opinions on them? (the corning one doesn't specify maximum temp)

Bear in mind this just MY opinion and I'm no where near as experienced as Dr Bob , but of those two I'd buy
the Scilogex because of the stirring function and the greater wattage allowing me more room for future growth( read: in case the amounts need to get
bigger). But the Corning plate you listed can go to 360 degrees versus the 280 degree limit on the scilogex stir plate. Here ;the best choice depends
on the work you will be doing.

I have heard of Laboy, they make decent quality Chinese glassware, not heard of the other one, but they might be made in same factory or might be
crap, hard to know. With either, I would have the expectation that it is probbly fine for basic stuff, some of the plastic or rubber parts may be
very poor quality, but the glass is likely OK. This might be a good starting point, and then you can replace anything not good, broken, or add
whatever that kit is missing. Both are cheap for the price of a basic kit for 24/40, but unless you are doing complex stuff, they likely will be
fine for most chemistry. I have even used a few Laboy flasks at work, that is what some vendors sell now in the US. They are thinner glass, but
that works fine in most cases. There shipping is also very low or free. Plus if it is really bad, you can complain to Amazon and make a claim.

The one with the Vigreaux column will likely be more useful, it seems to have more stoppers and clips, too.
However, Laboy has a better reputation for quality, insofar as cheap Chinese stuff goes.
If you aren't doing a lot of vacuum distillation, you don't need the strongest glass. But most people never regret buying quality.

Reacware is good quality. Nanshin is the same company. I am not sure if the glass is the same: it could be seconds or it could be just a different
brrand forr maarket saturation.
Laboy seems to be a different outfit but who really knows.
I have quite a bit from reacware and have had nothing fail except a dropped flask. I also have a bit from other cheap suppliers. And I have only
heard good things about Laboy. I think either set will help you get started.

I Most likely wont be doing any vacuum distillations, and if i do, i can buy stronger glass.
