FAQ for choosing the syringe filter to steroids powders home-brewing:
1) Es necesario tener un .22 Umm que una solución estéril o el .45 da resultados aceptables con respecto a los peligros de las bacterias ? Quisiera señalar que caliente la solución a 100° C antes de la mayoría del tipo de esteroide.
Necesario.. Hmmm.. No, La verdad es que no. Solía usar un .45 todo el tiempo con las conversiones de finaplix. A .22 is a smaller micron filter and will filter more minute particles and is required by National pharmacopoeia (not sure if the international is the same) in the filtration methods to depyrogenate injectable medicines
2) Which membrane are the best for a steroid based solution ? PVDF, Nylon, PES? Whant about PTFE and other membranes such as glass fiber ?
now here is where you will find many differences of opinions. – .22 micron PVDF Millipore filters – Many guys have also moved away from syringe filters to cup/vacuum type filter systems.
3) Why my filtration is soooo slow ? Because of the .22 um instead of .45 um ? or the use of other type of membrane ? or the non-Whatman filter are poor quality ?
The filtering is always going to be slower in a .22 filter than a .45, It’s a smaller membrane your filtering through. As for the clogging
4) Did you experience many differences between whatman filter and other cheaper filters ?
if you buy knock off type filters, then your going to get what you pay for.. I wouldn’t trust them..Have you seen what an abcess can do?? Trust the tried and true names. Whatman isn’t just the only one.
5) what is the quickest membrane ?
You should not be looking for the quickest, but the best for what your filtering.
6) What about the quality of filtration of the vacuum filtration all in one unity. I used PES membrane. At first it was good, but I let it overnight with vacuum and the next day I could see some part of the membrane has been dissolved in the solution. I threw all the product. Poor quality. Maybe you know better membrane for sterile unity because it needs less work.
Muchas personas se han trasladado al vacío filtrado con gran éxito. Como para su fusión. Viene de lo que su uso como un portador y productos químicos utilizados en el proceso de. EO derrita la goma y también algunas membranas de los filtros. EO vino de un día que vieron el portador en Virormone prueba prop y notó que era el portador y mayoría de las personas que ha utilizado esta prueba prop siempre la ha amado. Así que pensé por qué no utilizarlo en otras conversiones. Fue entonces también encontramos que se derretirá más común tabiques (the rubber piece in the top of the multi-use vial) used in the bottling process. Which is why you will only see the virormone testosterone in an amp form. Not in a multi-use vial.
It’s also why I don’t use it any longer.

Lot of labs or distributors are using the following vacuum filter or Autofil Bottle-Top Filtration snow . It’s more faster and convenient than syringe filter.
