The problem is we don't have a vacuum pump :)



I would think that the old vacuum aspirators we used in HS/college chem
class labs would provide sufficient draw-down.  They only require a
couple of gal/minute water supply, and a small sump-pump recycling water
into a tub could probably used if domestic water supply is not
available.  Cost < $20 with minimal shipping costs
