Whatman... .20 or .45 ?

[wolfman87]

so this seems pretty much half and half to me. some people are saying .45 is fine and some say that .20 is the way to go. some even say that .20 is for water bases only. i don't want to bake mine so i'll take the extra time and use a .20 anyway. however it would seem that a .45 would be fine and the ba would clear it of any harmful stuff if it was left on the shelf for a week or so.

both are good as i used both and both have their own quality

Great...I get to look like the perv here. To answer your question, the chick in scoobysgyms avitar is Chloe Jones.

.20 is much better

You really have to use the .45 for any oil based gear. The 0.2 is for water based like winny.

If you filter a water based winny suspension you will filter all the active ingredient out. You can only filter water based solutions where the active component is suspended. For instance if you made home made bac water or acetic acid solution for use with IGF.

That really depends on how pure the solid and what is mixed...

ive only ever used .2 and i use a caulking gun and two screws to hold the syringe in place. if im filtering a bit i normally tape around the sides of the filter for support so it dont go pop on me. it still takes a bit of time but thats better than an infection and down time from the gym.
i also make sure its very warm for increased viscosity.

I used the 0.45um Whatman and have had infection, the same product, I have filtered through 0.22um and no problems now ...
From now on, I am using 0.22um.

Yeah I am a fan of the 0.22um also. Sometimes I run it through the .45 first, then the 0.22 to make it easier to filter.

Double filtering is a waste of time.

I have used
. 2um and .45um and have never had problems with either with infections or what not. But if you want to be more safe go with the
. 2 but it's a bit getting over 50ml through a syringe filter
. 45um though I can do 100ml no problem
