Thread: Please help - Bottle top filters - suggestions?

I’ve been using a filtering flask setup and it’s just a pain in the ass to deal with!! Any suggestions as to which bottle top would suffice would solutions/brews with up to 20% bb?


I know to stay away from PES. I’m thinking Millipore PVDF .22 bottle top filters.

What do you guys use?

man, I should’ve listened to another person in another thread about using bottle top filters!!!

Sometimes you gotta learn the hard way, I'm like that as well
This is why I tell you guys to buy pre-sterile equipment, much easier to deal with. I've done this for a very long time so I have plenty of experience. If you brewing bigger batches it's much cheaper and better to sterilize the vials yourself (or if you know someone close that can do it).

Only reason why I got the Buchner setup was because I can't get bottle top filters in my country and customs know what they are used for.

Yeah PVDF filters are compatible with both BA and BB. Be careful when filtering hot oil though. Let it cool down to like 30 degrees celsius.

Keep it simple bros!

so I’m still stuck as to whether to use the Zapcap-CR bottle top or the Millipore PVDF bottle top? Both being .22 of course.

Thoughts?

I'm not a fan of millipore in general. Those filters will do if you can't get anything else.
Haven't tried zapcap filters but a lot of the bros here use them.
I found this though:
"I purchased these zapcaps thinking they were the sterile ones but they are actually zap cap CR's which state on the package that they are not sterile. Other than that everything else on my order is working well. "

I used to like the nalgene filters but the plastic of the actual funnel can leak plastic sometimes. This can happen to the millipore filters as well. Don't know if it's the heat or the BB/BA that does it. This was long time ago though, and re-filtering the gear solved the problem.

Can you post some details on the Buchner setup never heard of it.
