Electric hotplate for boiling solvents

[w0mbat]

Would this hotplate (designed for food) be sufficient for heating up solvents (99% IPA, acetone, and MEK in particular)? Or should SWIM get something designed for chemistry, like this "explosion proof" one?

can't go wrong with Thermolyne or Corning.

*edit* laboratory hot plates are chem-resistant. although the first one would suit your needs, it isn't specialized for boiling solvents, and may not be chemically inert to organics.

i have several corning hotplates
they work great

For my purposes, would the first hot plate work for me if I were only 1) using it only for boiling IPA and 2) distilling solvents in a proper apparatus (i.e. if there were a minimal chance of spillage)?

If not, do you know any cheap places to but a corning or thermolyne Even ebay doesn't seem to have them for <$99

then yes.

ebay sometimes has plates for >99, like Thermo Scientific Cimarec models.
not stores, or buy it now. those fools always try to sell their items at ridiculously high prices

look at this one too

cool, thx. I guess the risk of explosion is miniscule, right (like when distilling acetone in a proper apparatus)? I like the idea of having a "normal" hotplate just because it's easier to explain in a pinch

luckily hot plates are not illegal and one neednt explain having one

SWIM is frugal and bought this hotplate at the local China-mart a year or two ago. So far bringing naphtha and heptane to a boil has not resulted in explosions.

How do you find the heat settings on this baby? Does the lowest setting bring it so high that it boils IPA, or does it have finer control? Just curious, thx for input.

that one is just 'turn it untill its hot' style...it boils water, but something like a quart takes awhile to boil...like twice as long as an electric stove. They will run a 10qt pressure cooker...probably bigger than that too but mine was a 10qt when I was using that hotplate. I cant really remember for sure, but i think at the lowest setting you can almost leave your hand on it.

edit- for the control its just on at the lowest setting and the knob is like a light dimmer, you can turn it up a little at a time.
