To be honest I haven't actually looked at them yet because I'm on a mobile but I will when I have time. I'm assuming they aren't sterile or they are unusable for filter hormone because of the price. All of the 10-20/packs that sell for $10-20 that I've seen are for cosmetic/vet/lab use.Despite them saying sterile, what if they didn't say that? Then what part of it isn't sterile? The outside of them? If the filter inside isn't sterile, then how do you safely sterilize it?
Seems kind of dangerous if the filter inside wasn't sterile. How could you be sure you completely sterilized it?
i'm asking because i really don't know shit about these filters, but i'm interested in learning their differences.
Descriptionwhat you fellas think about these syringe filters from amazon; $20 for 20 filters. Seem to be too cheap!
20 X Hydrophilic PES Sterile Syringe Filter, Diameter:25mm, Pore Size:0.22μm, Set of 20,for Ion Chromatography Solution Liquid Medicine Food Industry Beverage,Rapid Sterilization
Was planning on using these for filtering UGL finished oils.
Now you guys have me thinking twice about these filters because of low price of $1/piece. Amazon has other sterile filters listed for similar price. ie.
I will get some Whatman or Naglene syringe filters that are $3-5/piece. This way I will have a piece of mind and be sure refiltering of a UGL finished oils and my first brew has no quality issues due to bad filters.
Im hearing the same thing ...i always use 22um 25mm PVDF syringe filter...its the best for me..i actually order mines on ebay...maybe a no brand company but it never failed on me.I would stear clear of Naglene. Ive heard that they crack pretty easily.

Brother, when you show a picture with sexy gear vials with brand label and more than a handful of them, you know viewers are going to think you are likely selling gear. I totally see that coming. I am kinda jealous of your brew. Hoping to brew me some very soon but not nearly as much you though

Ok fellas, up till now ive just been filtering via syringe filter into sealed sterile vials. Can yall chime in on how you all go about sterilizing open vials and stoppers? I have a couple buddies that want some gear and i would like to put caps on the vials via a crimper tool. Not sure you can use that on a sterile vial that already has a stopper in it or can you?
You can pry the cap off and remove the stopper and then recrimp another cap once you replace the stopper but you will be forfeiting the low cost of open top vials. There are a few threads in here giving methods of sterilizing your glassware.

SterileAlso, do use a sterile syringe filter or non-sterile? Does it really matter?
Sterile
Why wouldn't you want to use a sterile filter? You want your gear to be sterile, right?
Oh okay, I didn't realize you were able to sterilize vials full of hormone in the oven after filtering, maybe I'm confused. Anyways, I stated the same thing, most bulk syringe filters on eBay/Amazon are non -sterile.Ye - obviously. If I were to buy an un-sterile I would sterilize in the over before use. I'm just having an hard time finding the whatman ones that i normally use under a quantity of 100. Honestly, just trying to see if there is an alternative to the Whatman that ppl here have had success with. @Lukesky152 stated he orders of ebay, most of the PVDF ones on there I saw are un-sterile.
