Second opinion on cheap heating mantle

Medyc - 8-3-2017 at 12:52

Hi guys,
Long time lurker, looking for an opinion on a cheap heating mantle I found on Alibaba (https://m.alibaba.com/product/60588406461/ZNHW-1000ml-Intell...). I'm not really looking for much from it. The scope would be occasional use this coming summer to quench my thirst in the lab (going into my final year of my medicinal chemistry honors program). If anyone has any experience with lab equipment from Chinese suppliers, or this mantle in specific I'd love your opinion,
Thanks.

Is that model suitable for your mains voltage ?

Is the power adequate ?
e.g. to boil off 1 litre of water in one hour requires 628 W of heating.

careful, i was going to buy a model for $58, turns out the shipping was about 150 and then there was another $80 fee because it was "magnetic and they needed to make sure that its ok to ship" if you actually get it for that price let me know because im looking for one too

Yes, otherwise I'd be linking a different model: ill be using 1000ml - 500ml capacity rbfs (500-250ml liquid per reaction) with 530W from this specific model and the power input is customizable at the point of order.
I'm just asking for peoples experience with Chinese suppliers through Alibaba and the quality of the products. Or any other cheap alternatives ($80-$150).

Similar to my experience. I asked for a quote. Their unit is ~$60 USD but the shipping cost and fees totalled $80 (still a very good price assuming decent quality). I'm currently trying to haggle the shipping cost; we'll see if a compromise can be reached. If so I'll keep you all updated as this could be a nice replacement for the aging units that many of us own.
