I try to keep things simple and basically idiot proof. I have been using these nalgene rapid flow disposable filters. Over I guess I like then EXCEPT the receiving vessel cracks when I use my little electric vacuum pump. They are just thin little hairline cracks but when the vacuum pump is running it sucks air up through the cracks. The cracks are always on the bottom and as long as the pump is on nothing leaks out. When I disconnect the pump then a small amount of oil does seep through the cracks. I of course immediately get my filtered product out of the vessel and into sterile vials.
I have decided that I need to go with bottle top filters that way I can use glass media bottles as the reception vessel. Glass shouldn't crack from the vacuum pump pressure. The bottle top filters still come as sterile single use units so I would only have to worry about sterilizing the media bottle. Sterilizing the bottle should be easy enough, clean, dry, put some ba in it and swirl it around until everything gets a good dose of ba and the dump it out and connect to the filter.
I just want to know if anyone has used the "Autofil" bottle top filters. All of the pictures are the front of the filter and I assume the nipple for the vacuum line is on the back because the Autofil stands have a rubber receptacle that looks like the nipple goes into it.
I need to know if I can still use my simple little vacuum pump with the Autofil filters or do I need to buy that ridiculously priced stand?
So can anyone help fill me in? Surely someone here has used the Autofil bottle top filters.
