A Fina Farm ? (What filter size)

[Skullfucked1]

I have some filters ordered from someone else but I misplaced the few I had lying aroud so I need to get some FAST.
My question:
-25mm Whatman GD/X Syringe Filter?

They dont say if the filters are 0.45 micron or 0.22. I am assuming it is but I need to be sure. Thanks

Nobody can answer?

most places are 45 , unless noted otherwise.
but, this is not definitive, sorry bro

Most use .45 but I have read many recommendations to use .22. .45 will assure bacteriological sterility, but there is still the potential of other contaminants making it through.

The people reccomending it arent filtering with 0.22's. It is BRUTALLY slow. Maybe if you are doing 10cc at a time but the drip is so fine that even with 10ccs of plain oil it takes A LONG TIME.
