I believe air venting just refers to one of the uses of a filter with ptfe membrane. They are sometimes used to pull moisture out of air as it passes through

You’re a good dude Ghoul. It’s nice you provide so much free information and harm reduction techniques. I appreciate the advice you’ve given me and my friends via PM and the time you’ve taken out of your day to help complete strangers. I misread you initially and I would like to publicly apologize for the mean and rude things I’ve said to and about you.

No need to apologize brother. Somebody's gotta keep me humble lol
I have always done well with Millipore PVDF, works great with EO and Guaiacol (When I used a lot of TNE). You just have to adjust the temperature and psi.
Nylon sucks, worst of the 3, blows right up, clogs and gets slow. I have never tried PTFE.
Millipore got better years back when they started making them thicker, handles more heat and psi than it did years back. Years back they were much more available as well. They used to crack and leak.
Glass media bottle instead of that plastic junk and a brake bleeder pump, plastic pumps are garbage!

Sir, what you just did... takes a big heart and a giant set of balls!
More people should act like this, I do my best to no matter what.
If you will check out some compatibility charts PTFE is the beat rated membrane for all silvents and chemicals.. according to all the searching I have done.. I have experienced nylon being slow as well... and those fucking plastic media bottle that come with bottletop filters has cracked in me before as well.. the best place for them is definitely the trash!!!
Peace
I keep hearing about PTFE, it has been a thought but I'm so use to and adjusted to Millipore for about 15 years now.
The tops used to crack and leak, it's why I shy away from cheaper models, but Millipore a few years back started making the clear plastic much thicker than in the past. They just keep jacking up the price and for about 4 years now only 2 places in the US sell them.
Amazon had them a few years back but at some point they become less available unless from GPZ or Med Labs.
Nalgene is the only brand I tried nylon, maybe other brands have better.
I am curious to what new companies out there are comparable to Millipore.
I guess what I meant by compatible is durability.
Millipore is made pretty strong while the cheaper options seem fragile.
Nothing spoils your day more than filtering the last 100mls of a 500ml batch via a bottle top setup , and then you see bubbles rising to the surface from the bottom plastic collection bottle.
I switched to glass a while back due to the manufacturing quality inconsistencies with the Merck stericup bottle top systems.
I have a few of the millipore sterocups 1000ml packed up.. i used a couple of them when I first started and I think they were the reason some of my gear come out cloudy, but i can say for certain. ... I figure i may use them for things with lower bb % like Test E and EQ. It is hard to find PTFE sterile bottle top filters... KS-TEK said they would nake some but it would be a coupke of months out.. that was about 2 months ago i never checked back with them. I've just been usung syringe filters and vialing everything up as I make it. I was doing bottletop filter and syringe filter but after I did some sterility testing both ways I found it to be unnecessary...
I don't have a cloudy issue with Millipore, BB at 20% no issue.
I have used EO and guaiacol, no issue. You'll have to lower psi and heat needs to be on the lower end.
But it sounds like PTFE is better.
Rude. Let's all hope our beloved source doesn't filter emails right after taking payment.
Anyway, I tried it with multiple proton accounts. So if they did filter me, they filtered my ip address+protonmail account.
Except then I used non proton mail and it went through just fine. Also I tried multiple different vpn addressess, countries, etc. Nothing went through and to this day still doesn't. Curious. Maybe they want some people to have to use unencrypted emails because theyre really cops and all this is all just a big sting operation.

I assume only the stuff from the EU warehouse is shipped inside the EU. How is it with getting stuff from the international warehouse into EU?
