Mundane question, but what kind of filter would you use for 10g or less of product?

I was going to get a whatman filter, .2um but they come in a range of sizes. Didn't know which one i should get, so somebody give me a recommendation :)

[Nottherealjfk]

Any should work. If I’m not mistaken, the sizes you are referring to are just the different diameters of the syringe filters.

Correct that’s what I was referring to. I didn’t know if it made a difference. Thanks for that!

You were able to get 10 pvdf .2 micron 25mm whatman syringe filters for $13? Where?

what? No. The size, .45 vs .22, represents the size of the pours in the membrane. You want a .22um. Bacteria sizes range from 0.2 - 2.0um.

Syringe Filter, Sterile Syringe... Sorry! Something went wrong! (https://www.amazon.com/dp/B07FJPP8FH?ref=ppx_pop_mob_ap_share)

I hope this was the right filter, it seemed like it was.

Those are pes not pvdf. You want to buy pvdf. Pes will work for the vent needle filter but not for the brew filter the BA and BB will break down the pes filter material

[teejey]

I think .22u ptfe will work as well. I got 30 of em for 20 bucks off Amazon . Make sure they are sterile. My first order came lose in a bag.

Well I don’t doubt you, but there was less than 1 ml of BA and BB combined.

How many ml can you filter through a single one?

Great question. I have no idea. I only pushed 20 ml thru this one

With the whatman pvdf I can filter over a 100ml with mct oil,ba, and bb. But if it has guaiacol I can only get around 50-60ml
