Heating mantles from India
Ebay is replete with heating mantles from India. As an example, a 1L mantle with built-in temperature control, 1L size, with shipping, is in the
$80-90 range. I saw similar listings for mantles from China. In general, are Indian and/or Chinese heating mantles a good buy?
I'm sure many SM members have these mantles, and therefore have opinions on their value/usability. I would very much like to hear them.
Thanks in advance!

I am from India and I use Indian heating mantles of all sizes from 500 ml to 10 lit. (Some custom built too for 2 lit kettles).
Generally of good quality and sturdy design. prices range locally (without shipment) between INR 1000 to 4000 (US$ 15 to 60).

I like the older US ones in good shape and have bought many at good prices. Heating mantles will last forever if treated kindly. I tried getting
information on one from a manufacturer but as in the case of balances they balk at support info and try to make you buy new ones.

I have bought some kitchen equipment from India
and it appears to me that Indian products are simple and robust and cheap
Chinese products can be very cheap, high-tech, but not so reliable.
Based on superficial knowledge I would buy a heating mantle from India rather than China.
With modern manufacturing techniques and cost considerations,
in a commercial environment, repair is not an option due to labour cost.
My day job is repairing industrial electronic equipment
the main reason that we are in business is the poor investment in UK industry,
leaving production lines of decrepitating equipment needing occasional emergency repairs.
Repair of consumer items is not a good business to go into !

Yup! Usta know lots of guys in the electronic repair business. TVs, VCRs, Stereo equipment, pretty much anything.
Everybody made a decent living. And then, the world changed. Electronics became better and better, and cheaper and cheaper.
Last time I bought a DVD player, it was $40 bucks. It has operated flawlessly, for a decade.
Play CDs too, and it produces beautiful clean sound. No distortion, no Dolby required....nice.
Perhaps HiFi is somewhat diminished, as it isn't Vinyl, but it is plenty good enough.
Amplifier? No, not required. My TV produces beautiful stereo sound. Sounds so damned good, I sometimes mistakes soundtrack noises, for outside
street noises.
Electronics repair guys are going the way of Blacksmiths......and Payphones. Gotta find some new way to express their genius.

gsd | Would you say this is also true of Indian made lab equipment in general? What about their glassware?
Goodness knows it'd be nice to have another option for affordable flasks...maybe even Perkins triangles since china won't..

There are several Indian manufacturers who make excellent quality laboratory glassware. following 3 I have personally used and would highly recommend.
A point to be noted here is none of them makes there own borosilicate glass. Glass bulbs and Tubings are imported from either China, Eastern Europe or
Germany and all sorts glass items are made by glass blowing. All these companies do proper heat treatment and quality control.

For Overhead and Magnetic Stirrers, I would recommend:

Good, sturdy equipments, extremely affordable.

You can get details of several mantle suppliers here:
https://www.google.co.in/?gfe_rd=cr&ei=kym9VpLUI8fCuATai...
Some specific manufacturers are:
http://www.sakav.com/heating-mantle.html
http://www.sunlabexporters.com/heating-mantle.htm
http://www.ganeshscientific.com/heating_mantle.html
However I must say that I have not dealt with them personally.
You will have to ask for packing and forwarding costs to them to your locations.
also the current exchange rate is approx. 1 US$ = 67.5 INR

I certainly appreciate all of the input, but for now I am settling for 1 L and 100 mL mantles from eBay. With glass wool "stuffing" I think these
should cover my needs (still mostly undefined) from 25-50 ti 1000 mL.

I bought a 1L unbranded Indian heating mantle from Amazon a few months back. It works well, especially considering the price ($85). The only issue is
the input voltage, 250v instead of the 120v we have in the US, so I had to purchase a cheap adapter ($15).
