It would he pretty stupid to filter it... back into a vial of dubious quality...

Get some ultra spec vials.

Hey guys, don't worry, we're always here.
International shipping applies to the EU, Southeast Asia, and the UK.
For shipments from China, all products are shipped in one package and not in separate packages.

You people made clear in emails that you only ship to the USA. Is this not the case?

I’ve found the .22 35mm is way easier to push the oil thru than the 25mm discs.

Yes, between 25 and 35 that's almost close to 50% more surface area for the oil to move through

Actually, close to 100% more surface area if I remember my high school math from 30 years ago correctly.

Unfortunately I wasn’t paying attention when I bought the pack of 50 filters did I realize I got 25mm after delivery. Needless to say my forearms are getting a workout

Appreciate it. I should have been clearer: 50 pcs would be a good middle ground for me between 20 and 100.

The smaller the syringe you use, the less force you'll have to apply to the plunger. It might be less convenient, but dropping from a 10ml to a 5ml might be better. Just be careful not too apply too much force or you risk blowing out the filter. I used to use 20ml syringes, but got tired, literally, and dropped down to 10's.

The 35mm filters were easy with a 10ml syringe. I just need to get thru what i have . Don’t want to be wasteful
