Define "high volume"?
If its under 150ml its almost not worth buying all the gear like a vac pump, stericup filters, septa tops, etc when you can just buy a few needles a big syringe and a couple filters. ( youll need the syringe and needles as well with the stericup.)
ya this is how im looking at it. Once i realized i had to get the pump and everything i just dropped that idea and went back to the basic method.
