I have converted Fina twice and never had any problems. Check to make sure the filter isnt to tight on the syringe. I noticed when I did that the flow was really slow, but also make sure its not too loose otherwise you will lose some Tren.

Then again, better safe then sorry so why not spend the extra $8

yeah, make sure it is tight definitley. Also, use a 3ml, i know more loading the syringe etc, but you can put much more pressure on the oil, and it squirts out faster. I could barely get my oil to move in a 20ml syringe, let alone a 10 ml. But, again it must be tight. I learned my lesson after i accidently had 10mls all over me.

This is a good thread. I personally always buy extra filters. Not only can it be a bit of a bitch to get through the filter after you have already filtered 10-20 ml's but sterility then comes into question when you see how dirty that filter gets.

My thinking on that is you mine as well spring the extra couple bucks so that you can ease your mind about the sterility of your end-product.

I am going to make a copy of this thread available to the "Chemical" forum as well.

Anyone purchase their own materials instead of using a kit? Worth the effort?

Any of you guys know the psi rating on syringes when filtering???
