Since qualitative hot plates are apparently incredibly expensive, at least those I found, and heating things on a kitchen stove isn't really safe, I
was wondering if it was okay to use a heating mantle to somehow roughly heat up flat bottom containers?draculic acid69 - 20-4-2020 at 16:30
I agree with the post above;
. I use two ot the dimmer shown for my dual hotplate, 1500W and 500W
. I use one for my 380W heating mantle
For increased safety, and with a cooling fan for 1500W load in warmer climates, I suggest a slight upgrade https://www.ebay.com.au/itm/220V-4000W-SCR-Dimmer-Motor-Spee...
choose controller + case + fan
this was the first lising that I found - search for better pricing.SWIM - 21-4-2020 at 14:22
There are such things as heating mantles for beakers and even Erlenmeyers, but they only work for one size so they're kinda limited in use.
I'm sure there must be something where they're just what you need, but a hotplate is so much cheaper and more versatile.
If you want to evaporate things to dryness much then an electric skillet may be a good possibility.
They have thermostatic control, so you can set one for say 100 C, and the pan surface will maintain that temperature more or less so you won't crack
flasks if you leave them too long. https://www.homedepot.com/pep/Presto-121-sq-in-Black-Non-Sti...mackolol - 22-4-2020 at 12:15
Yea, I really recommend these ones. They're dirt cheap, in Poland one costs as much as good 500ml two necked flask. Despite their price, they're
great. I have one and it heats wayyy higher than my hotplate stirrer and way faster.
Everytime when I need high temperatures and not necessarily super good
temp control I go for it.
