I own a Corning PC-351 and I like it aside from the stir plate magnet,which seems to be a bit weak. I sometimes have trouble forming a vortex with my
1000 ml round bottom flasks, even with an oval shaped stir bar.
I notice that some brand of hot plates rate the stirring capacity of their hot plates. The IKA RCT, for example, is rated at 20 liters for "Stirring
quantity max. per stirring position (H2O)." Is this actually true? I don't need anywhere near 20 liters, but having a much stronger magnet would be
useful, especially when used RCTs aren't very expensive.Deathunter88 - 9-2-2020 at 12:53
Check your stir bar first, they get demagnetized over time. monolithic - 9-2-2020 at 14:37
