Isopropyl alcohol for homebrew

There are equivalent guidelines for Europe (EP) and UK (BP)
They aren't widely available at all. Atleast not the eu equivalent. Don't know about UK. USP however was easier to find. But it's not correct that you need this.
 
Not really. USP is a US thing. And Europeans do just fine. You just need to get your stuff from a decent reputable vendor.
I'm convinced Amazon sellers slap on USP in the title of their listings for BB/mct, etc just to reach out to steroid homebrewers

I’m sorry I meant USP specifically for injections

USP is just the standardi

This has also got me to thinking about how people say they get pip or are allergic to a type of oil. What if it’s not the type but the oil just isn’t up to standard.
 
Thanks!
Sorry, i know how stupid my noob questions must be to you experienced guys. I will not make a move until I follow through with your advice.
Does the whatman 0.22 filter work in both directions? In the tutorials it says to draw up the homebrew into a syringe, place a whatman on the syringe, then empty the syringe out via the whatman into a sterile vial.
Can it be done the other way around? In the first step, draw up the homebrew into the syringe via the whatman. Because the homebrew is hotter, and easier to filter and move this way
Also is whatman the only way to go, or would any 0.22 syringe filter be okay, is there a reputable source
Syringe filters are one way only, you'll have a shit time trying to draw up your brew through a filter
 
Before filter important but not crazy. After filter is sterile, first time get sterile vials, fill and go. Read more on the details but after filter is what matters. BA keeps bacteria from growing.

If we were to simplify things, Pharmacopoeia standards just means filtered from impurities. You can buy non usp/ep/bp castor oil and filter it with a .45 μm filter and call it Pharmacopoeia grade.

Allergies are an immune response to a perceived threat that doesn't exist, that starts from an antigen. You can't filter antigens.
 
Drawing up with the filter will contaminate then filter and will just get pushed back out when you fill your vials. You need to do a lot more reading.
 
Are you sure
The type of syringe filters we use for filtering gear yes absolutely are directional only

There are different type of filters, some are made for filtering when drawing. We don’t use those. They don’t have the filtering capabilities we require to filter and sterilize gear.

If you do even just a tiny bit of reading you won’t need to ask these silly questions

The ones we use, you draw the solution into the syringe. Then you attach the syringe filter and press the solution through the filter and into a sterile vial.
 
Are you sure
I suggest you dedicate one hour a day reading or just do it during meals and you will cover all the bases needed to home-brew successfully.

It is not rocket science, anyone with basic reading comprehension can do it with enough trial and error.

Enough with this silly questions and do your proper research, by next weekend I guarantee you can brew a small simple batch yourself.

Good luck.
 
No offence, It's not a silly question. I've read a lot of tutorials and not one has warned that the syringe filters are one direction.

How do i tell if the syringe filters are directional

Thanks!

Have you read the sticky titled homebrewing bible. It will never ask you to filter from your beaker ever. If you follow the introductions to the letter, you will have no problems. The ancient basskiller instructions with old pictures also works, just google it or search the forums.

I don’t know how much more hand holding we need to do here, do I need to copy post the whole thread?

This is because no one is stupid enough to ask this question. It’s common sense
The amount of force required to push the solution through the filter Is so great that the oil needs to be warm so the viscosity is lower and many choose to use a calking gun to create more force than the hands can. You aren’t going to be able to draw much up with the suction of a syringe plunger if you were stupid enough to do it backwards.
Just Google “ how to use syringe filters” and it will explain everything and you won’t have to keep asking stupid questions.

Yes you’re asking silly questions. No you absolutely have not read much and if you have your not reading about brewing because you don’t even know the simplest of things.
You have been told to do some basic research and then come back. You know absolutely nothing and are bothering people with moronic questions. We are happy to help with questions but what you’re asking is completely stupid and shows you made zero effort other than lying about doing lots of research.
