.22um or .45 syringe filter?

[Cajun897]

what is more commonly used are you really taking a chance with a .45 or no?

 

[Docd187123]

0.22

Unless your a rebel who likes living life on the edge.... but in that case why filter at all.

Lol ok got it man no powder gets trapped right?

If you have powder going through the filter, you have issues....

Lol ok no hormone because it should have dissolved by then. Guess I gotta be a little more careful of what I say

 

[Wunderpus]

It will not "catch" the hormone in a .22. EVEN if it did, right, wouldn't you prefer to "lose" a bit of hormone and also grab all those nasty contaminants?

Not to totally hijack this thread, but I just bought new syringe filters and messed up and didn't get the individually packaged, sterile ones. Is there a way to sterilize them or just toss? I assume they would melt in the oven if baked like glassware, but I haven't googled it yet.

 

[master.on]

Only use 0.22 for homebrew
some pharma labs use 0.45 but only because they use clean rooms

Not at reasonable do

You can run a few ml of ba through them and let sit for a bit. At that point I'd either toss the first few ml of gear running through or filter it back into your beaker full of made product.

I thought ba didn't actually kill bacteria, just prevented, which still isn't the right word(deterred maybe), it from forming in the mixture.

It should do both it is alcohol. I did the same thing the first time I got some lol got a bag of 25 of them

This is absolutely true.
Look at the many reported cases of infection (from bacteria) despite the burning injection pain from high BA content.

How does alcohol not kill germs? Bb can also cause pip and so can shitty raws

Bc when you go to sterilize your gear you want to more than just "kill germs".

FDA has not cleared any liquid chemical sterilant or high-level disinfectant with alcohol as the main active ingredient. These alcohols are rapidly bactericidal rather than bacteriostatic against vegetative forms of bacteria; they also are tuberculocidal, fungicidal, and virucidal but do not destroy bacterial spores.

Alcohols are not recommended for sterilizing medical and surgical materials principally because they lack sporicidal action and they cannot penetrate protein-rich materials. Fatal postoperative wound infections with Clostridium have occurred when alcohols were used to sterilize surgical instruments contaminated with bacterial spores 497. Alcohols have been used effectively to disinfect oral and rectal thermometers 498, 499, hospital pagers 500, scissors 501, and stethoscopes 502. Alcohols have been used to disinfect fiberoptic endoscopes 503, 504 but failure of this disinfectant have lead to infection 280, 505. Alcohol towelettes have been used for years to disinfect small surfaces such as rubber stoppers of multiple-dose medication vials or vaccine bottles. Furthermore, alcohol occasionally is used to disinfect external surfaces of equipment (e.g., stethoscopes, ventilators, manual ventilation bags) 506, CPR manikins 507, ultrasound instruments 508 or medication preparation areas.

All my life I've been lied too....

Ba isn't gonna be a 100% but it will be something. Your a homebrewer. You will not be 100% sterile on everything, but we try to come as close as we can. Do you sterilize your working area? Hopefully you try and come as close as you can. You can choose to use the ba or not. Do you think the ba won't have any benefit or kill any unwanted bacteria?

When I brew its probably more sterile than most ugls I make sure everything is clean

Me too. I go an extra couple steps to make sure. Why not. I figure, think of the alternative.
