i'm about to order some filters, but i noticed they come in 4 different sizes. so, i'm a little confused. they list: .20 .45 .45u and .2um i have they typical 3ml syringes, which size filter do i need?
also, how much can be ran through one filter? we have 2 open vials of test and 2 open vials of deca that all need to be filtered. should i get 2 filters, one for the ALL the test and one for ALL the deca? should i get 4 filters, one for each vial? or should i just get one filter, for everything? i'm guessing 2.
thanx
