Hey guys, I started converting some fina last night but I've run into a bit of a problem. I've got everything pretty much pre-filtered and I'm pushing the tren through the Whatman filter into the final (sealed) vial.
So far I've got most of the tren in the vial but now I'm having a hell of a time pushing the last 4cc's or so through the filter. I have to push like crazy just to get a few drops at a time.
The question is this: Everyone talks about how easily these filters clog. How exactly would I know if the filter is clogged? I mean aside from the tren not going through very easily, does the filter look distinctively darker or caked with crud? I'm real curious because my tren was very clear after I'd pre-filtered it and it seems strange that it'd clog the Whatman filter so easily.
And just a thought, but does anyone think that it may be a pressure issue inside the vial that's causing the problem? In addition to the 18g needle through which I'm filtering the tren, I've got a 23g needle sticking out the top of the vial to balance out the pressure. Does anyone think that there just isn't enough air escaping out the 23g pin and that's why it's so difficult to push anything back into the vial? I'm starting to believe that is the problem because, whenever I unscrew the syringe from the filter, oil pushes back out the top of the Whatman from the pressure inside the vial. I'm considering swapping the 23g pin with an 18g to see if that helps. Also, am I risking infection if I just took the top off (these are the vials with the screw tops from finakits) and squirted the tren directly into the vial, then screwing the top back on again?
