Lol my first brew ever was today, results and pics in BrewPorn thread ;)

Though I don’t want to give actual advice on this one, you know, because it’s a pretty iffy thing... I’ll say this. I may or may not allegedly used non sterile .22 filters today and may or may not have ran isopropyl through it last night to air dry.

but that’s just what might be what I literally did the past 24hr so if you do that and It doesn’t work out then sorry bro’s. I just pinned .5ml too see in my rear delt
Did YOU pin your rear delt or your woman?

Not sterile

it says here that it is not sterile. would that be a problem?

There you go @Euricomiranda - you’ll want to allegedly sterilize it if you’re allegedly making gear ;)

not sterilized has never been a problem from all of my years reading reviews. There are always theories about it, but I can't recall one instance this has caused an issue. The filter obviously takes care of the oils sterility. As long as your oil transfers from the filter to a clean environment you will be perfectly fine imo. If I had to estimate a number, I would guess that I've seen well over 1000 vials used with zero issues with filtration like this.

One thing I would be sure of prior to exposing my filters to caustic substances is what they can handle regarding membrane breakdown. Just something to keep in mind

thank you my consecrated. I will sterilize using 90% alcohol

70% is actually better for sterilization I have heard, but of you have 90 already, that’ll be fine.

70% is what you want to use. 90% evaporates too quickly to be very effective at killing, 50% isn't potent enough but lasts on the surface.

Thanks for XKawn’s itinerary - super glad he gets to bypass the travel bans!

So even if it’s one of those enclosed syringe filters, you don’t think sterilization is needed? Granted, I don’t expect any bacteria to get in that likely area, but you never know. With a PTFE filter, that should be able to handle 70% isopropyl shouldn’t it?

When you're a rock start you can pretty much do as you please!

Essentially almost all membranes have a threshold with iso alcohol, and it's generally described as limited. The same applies for BA as well. One thing I've never been able to pin point is the legitimate meaning behind the term limited. In a few articles I've read regarding BA it's been generalized that 3% or less in a solution is acceptable but more than that and there could be membrane breakdown. I can't find relevant info like this regarding iso alcohol.

if one was to sterilize the filter you could use an autoclave, pressure cooker, or maybe even dry heat. The filters can withstand heat to a certain degree. Hopefully there are specs or msds data points that can help obtain this info.

My guess is that yes, there is a chance bacteria could be on that tip after the filter. There is always UV sterility for clean products, which I believe is how most items meet the "sterility requirements" in the first place once they are inside of plastic bags meant for resale.
 
To expand on bacteria being on the filter post membrane...

Keep in mind that bacteria has to live in oil with BA, with zero air. This doesn't help the bacteria in any way. The larger worry, imo, would be what the oil is being received into and then subsequently partitioned into after filtering. That's going to be the weak spot imo. That and the method of transferring the oils to their final destination (10ml vials)

Good stuff man!

that's why ptfe filters are preferable to pes filters right? i was reading through this thread somewhere and saw there was some kinda flaw with pes filters but i couldn't remember what it's catch was.
 
From my understanding, PTFE is the type that handles harder solvents

https://greenbioresearch.com/choose-right-syringe-filter-chemical-compatibility/ (How To Choose Right Syringe Filter -- Chemical Compatibility)

here there is compatibility to all chemical listed.. BB BA and others... in another charts i found ethyl oleate too and guaiacol (metoxy phenol)

PTFE aka Teflon is the best ✊
 
can i put the becker on top of a pan over flames and make my cook?

Not advisable tbh. Absolutely no water for starters. Just get a stirring hot plate. Easily controlled and mixes for you too
