Coleman 502 gasoline stove


It only produces soot when the flame is burning yellow.
When it is fully up to temperature and operating correctly,
the flame is blue and there is absolutely no soot.

It goes yellow if the generator is clogged or fouled, or if
the fuel is old and spoiled. It does burn yellow like that
for a few minutes as it warms up when first started.

When it's working right, it's a clean, very hot, blue flame.

Look on Ebay for "Coleman 502 stove" to see it.

I do like the look of the Indian-made stirrer mantles linked above - I wonder if they're any good for the price?

Maybe you should 'take one for the team', vibbz and let us know! :)

Which links? That hotplate/stirrer in your post I can imagine being pretty good, actually - especially for the price. Kinda gives a vibe of some of the better Soviet stuff IMO - kinda built ugly, but sturdy and functional.

India's up and coming these days, and they might have started to get up there, and even better than the Chinese at some things like this.

Support Indian home industry! No, seriously - I think you should seriously think about getting one. *Much* better than that Butane tea lamp or whatever in your earlier post.

I'm seriously thinking about getting one of the Indian heating stirrer/mantles linked up thread when it's time for me to get one. :cool:

And I think there's not much home chemist from India.

That may be so, but you've got at least a couple of companies manufacturing affordable, semi-decent looking lab gear now and that's a good sign.

I bet there will be a lot more small chemistry companies popping up as India takes on China in becoming the world's premier supplier of chems/tech assembly etc.

I'm seriously thinking of springing for one of those Indian heating mantle/stirrers myself when I get my RBFs etc. - I'd be willing to take a punt on them at 80 EUR.

I already set up my lab and chemicals are also set.
I really need a decent heating source and I think this one is really good. I will buy it maybe in a few months .
I am also planning to upgrade my lab and stuff. My videos have to be made better too .

It's ugly but who cares ?
Power could be a little bit more but that price is hard to beat.

That said, I never regreted investing 500 Euros in my second hotplate. The first was a gift so no complains there either but a quality hotplate will make everything you do more pleasant and precise.

I also have a bunsen burner that runs on a camping gas bottle for whatever I need to do away from home but for this, any regular and cheap camping stove would have been enough.

With a little tinkering from someone who can hack electronics a bit, you might even be able to safely and quite easily soup up the power on that Indian Soviet-looking hotplate sometime down the road if you need more power.:cool:

Lol Soviet looking,but that's the best I can afford. Let me do more videos in YouTube so I think I can make enough donation or something to buy even that Soviet thing

Hey, I *like* the way it looks. :cool:

Good luck with your channel - it's really good to see more actual amateur chemistry on places like YouTube.

Is that blue and white bexco mantle hiding a Variac in that little box where the dial is.
Why would they need a bulky box hanging off the side when a tiny little circuit board will do.

That's a really nasty stuff. You don't want to mess with bexco mantles. That thing gets way too hot within seconds. To be honest it's not safe. I've seen it being used in my highschool lab and that thing shoot sparks out when it gets on.

That's a really good question - well noticed. :cool:

I did think that, especially in the image of the smaller BEXCO mantle, that the heat resistant lining looked really sloppily applied.

I wonder what they look like inside? I also wonder what they might have skimped on, or built sloppily and whether they're hackable? For 40 EUR for one delivered, I might take the risk if I get the cash.

It'd make a nice write up for the forum, at any rate - an unboxing, review and treardown of a cheap BEXCO mantle. :)

I am planning to get the antslab hotplate and stirrer I am collecting cash to get that. It's around 100 USD and I am not even close

Are there not also colleges/universities which might get rid of/sell cheaply surplus equipment that you could ask?

Also, why not ask AntsLab if they'd be willing to sponsor your YouTube channel by giving you a discounted hotplate?

You know, the more I think about it, if those BEXCO mantles are nice and simple inside (and I'm thinking they will be) - if they at least have stirring motors worth keeping, and the insulation - they shouldn't be to hard to hack. Maybe upgrade the power circuitry - more torque on the stirrer, more power (safely) to make more heat?

It'd make a great YouTube chemistry/electronics video anyway - brand new heating mantle with stirring for around 50 bucks delivered that can be easily hacked/upgraded? I'd watch the hell outta that. :cool:

EDIT: Hunh - the Ant's Lab hotplate is only US$60 - that's honesty a steal if it's any good at all. :)

Apologies for the double post, but it's quite long:

Ahh, damn - I knew it was too good to be true - the 350W 250C (quite underpowered as mentioned above) hotplate is USD 100, the 600W (pretty hefty powered) 350C hotplate is USD 210.

IDK about 250C with the 350W one - my old skool UK-made 30-35 year old 450W hotplate struggles to get much above 230C measured at the plate with a digital probe thermometer.

The AntsLab magnetic stirrer with no heater is USD 60.

They also do a pretty cool looking overhead stirrer for USD 185.

Still great prices if the equipment is as well-made as it looks like it might be IMO.

I'd like to start seeing these inexpensive Indian-made equipment being used by smaller and amateur chemists more than the Chinese stuff. You've had your time China, move over - now it's time for India to shine! :)

I honestly do - it should be perfectly good for stuff up to at least 200C - if you want/need to/can afford to get the 600W 350C model for USD210, then that should allow you to perform higher temperature stuff like, I dunno, distilling H2SO4 or whatever.

That overhead stirrer for 185 USD also looks pretty cool - they're not usually easy to find and/or cheap, and can come in handy in quite a few situations.

Did all the BEXCO mantles overheat/spark when you saw them at college, or was it just one or two? I'd like to take a closer look at one, especially what they've used inside, because they're insanely cheap. If they can be hacked/circuit bent/made safe easily and cheaply enough, then they're a great resource to have IMO.

That Ant's Lab seems like a pretty cool small supplier - they also sell Alumina heating crucibles, mortar and pestles and grinding balls. Some other Quartz and Platinum stuff as well. Nicely done whichever forum poster discovered them. :cool:
