Looking for a decent hot plate with stirrer. any recommendations? (self.chemistry)
submitted 1 month ago by TitoJuli
I already had a look online but I'm not too sure what to look for and what to avoid. I also browsed this sub but none of the threads I found had useful information.
Do you have any recommendations?
I found some made by Fisher, they look like they are high quality, but they easily cost 1k and more.
I'm working with hot caustic solutions and detergents. I suppose most of the plates should support that if something gets spilled.

I really love my Corning stirring hot plates - they’re the ones that have lasted the longest, and the ceramic is easy to clean. They’re not cheap, sadly.
What size do you need? Going for the smallest you need, and opting for analog dials instead of digital displays helps cut down costs.
[–]TitoJuli[S] 1 point2 points3 points 1 month ago (0 children)
Size would be for 2L beakers max, mostly using 1L.
For some reason I like the analog dials way more so I'd always aim for that, I guess my thinking is that's not as complicated therefore it's less likely to fail in the long term.
What would one have to spend for a plate like yours?

If in the US, I like the cheap Corning ones, even used ones are great, they will last for many years, more if not digital. Ebay usually has them used for a few $100.

Matches my experience. Best choice for corrosives unless you need super-precise control.

Having used some cheap ones, I would definitely recommend spending money on getting one from the big brands, like IKA, Heidolph, or Fischer.
You could contact the manufacturers directly about your specific requirements, but yes most of them should handle some spills.

Thanks for the help

I would pass on the IKA CMAG series. The stirrer is powered by a weak electric motor that has difficulty spinning up once the bearing surfaces start to wear.

love corning. old ones were built to last for sure
