Yeah, they definitely have sterile filters, and they certainly look good... I'm just concerned that the nylon filters (which I see for sale all the place, and with various kits) are being sold as sterile, and I can't find any reference anywhere other than those sites selling them that they are offered as sterile. And anyone know what an appropriate filter media would be for filtering hormones, disolved in ba, bb, and oil? The media available as sterile seem to be, with the same pore size (0.45µm):
Cellulose Acetate
Glass Microfibre
Polyethersulfone
Polyvinylidene Fluoride
Also, from looking at this, I notice that some companies are selling the 13mm filters... And what we (I) want are 25mm (since the 13mm seem to have a 10ml volume limit before they are spent).
