took me forever. i remember the first 30ml took me 1 hour and it was hard work lol so i would say hour and a half for the 50ml. using a .45.
And Im not sure what you mean by pulling the other one?! i just filtered straight into a vial.
Im never using a standard syringe filter again. I need some info on the hand pumps please. Also will my unfiltered gear that i have left over be fine to filter at a later date? Thanks.
It's a theory of mine:
You use one syringe to push the oil throught the filter into the vial and in the same time another different syringe for pulling the air inside the vial, creating a vacuum in the vial and facilitating the aspiration of the oil.
