We use aluminum heating blocks on hot plates for all of our syntheses these days. I had them custom made by J KEM to fit our round bottoms. The up-front cost is a bit, but they are less than what I found for the coated ones. You can have them made with a thermometer hole to fit a thermocouple in to better control the temp.

I need to offer some options to replace oil (silicone or mineral) with a different material for heating baths. I’m also looking at heating block options and have a number of suppliers to review – cost may be an issue here.
Ideas? The Google has failed me this morning.
