thanku!yes ive seen some kits from laboy as well 32 or 36?piece.there kits, the 3neck only went to 1000ml.i was looking for 2000ml so not sure?buying in pieces is probably more expensive,but kit does have its perks too.think kits were about 180usd,while buying a larger flask seperate is about 130usd.decisions decisions,chem sure is complicated,lol.......ok, im researching adapters still need to learn on that!
