ok i got 1 hotplate that comes with a magnetic stirrer.. and tried and tested, 1 stirrer can only work with 1 beaker + stirrer bar.. unless the beaker and bar is very small, 3 cm max, it wont stir if there are more beakers.. hmmmmm need to keep the H2SO4 cool at 0C before pouring and then maintain mixture temp at 20C max. That means i need ice bath and that means i need something to hold water and ice with my beaker in it...
aluminium tray that is small enough for the hotplate and no choice, would have to do it 1 by 1 slowly.. unless i can secure another hot plate.. doubt it, no space in the fumehood...ok assuming 3 hrs per batch, i got 4 batch and thus 12 hrs and thus 2 days worth of 6 hrs each.. i need ice too, and thus cooler box..need to check with the lab for this..looks and sounds feasible
smoke on the water.
