Like what?Suspensions need quite different filtering method,than solutions.
This exactly i do..fist the water ..You need to filter separate the water and the melted api.
Probably you mean.I think you should try the syringe filter method,and filter it warm,but not hot,try 2ml at one time
1.filter the water+BA+tween 80 to the steril final vial
2.filter the melted api+solvent in
3.shake
Thank you my friend ..No need to warm the BA and the tw80 ,
you need to heat to very hot to melt the stano api,do it with BB only
