Well the syringe filter is a five bucks.
Sterile sealed vial 50ml. two fifty.
some syringes a few bucks
1 l grape seed oil. twelve bucks
better off just buying it prefiltered.
Or back in the day when i was in a bind i would bake a coffee mug (not true steriled)
Attach a coffee filter to top using rubber band.
Heat Grapesead oil bought from Vons in microwave
pour onto filter
use syringe to move GS oil from coffee cup to sealed sterile vial.
Again this is not the safest method but i did it four times and never got an infection.
