filtering questions??

[quasimodo]

Need to make a new batch in the next few days, gonna make 4x 50ml test e and 2 x 20ml test e. If i use a 20ml syringe and put 20 ml through the whatman filter attacted to the 50ml vial, can i remove the syringe and draw up another 20 ml and continue filtering and remain sterile, can I also remove the filter from one vial and place to the next vial?? will this keep things sterile??

its esasier to filter with a 10ml.

leave the filter and needle in the vial. uncsrew it and attcah a needle to draw with. then take it off and attach it back to the filter in the vial.

and yes you can move the filter from one vial to another.
