*Turn heat off but keep stirring to prevent clumping pre-bead forming | |||
*Let cool in dropper before dropping | |||
*Move to Dr Fox's automated pumper when repeating bead synthesis | |||
*Use wide dish | |||
*PVA-Alg #2 done in wide dish, dropped with disposable dropper, turn off heat ~1 min before dropping | |||
*Don't fill disposable dropper all the way > cooling solution will come out | |||
