Lol. The filter is no different. When they say sterile, they are talking about the way it's packages. It comes in a sealed package as opposed to an unsealed.
It's not the actual filter that is sterile. So you are paying for them to seal the filter but as soon as you open it, and the air touches the outside it is the same one you can purchase for less.
Do you see what I'm saying? If you don't believe me, contact whatman and ask them.
For IM, once you solution passes thru the filter, inside the housing, is where it becomes sterile. The inside of that filter is no different whether it says sterile or unsterile. Do you think you would filter something to sterilize it in an unsterile environment?
There would be no point in filtering, if your filter could contaminate your solution. They are speaking of the way it's packaged and nothing else.
Read the sticky in this forum. I think it's the kitchen chemist cook book or one of them. It's covered in there as well.
When you are buying bottle tops, they are all sold as a sterile unit, but the only thing that really is sterile is the receiver bottle.
And how could the filter in a syringe filter remain sterile? As soon as you connect a syringe and push an unsterile solution thru it, it would no longer be sterile.
The filer membrane is what stops all particulates from getting thru, that is the sterilization process.
SO YOU DO NOT NEED TO BUT STERILE SYRINGE FILTERS. FOR ANYONE GETTING STARTED DO NOT WASTE YOUR MONEY ON THEM. THEY ARE SEELING YOU STERILE PACKAGING.
Contact whatman and they will give you the same answer.
