* Yes, the .22um "150ml
Nalgene Rapid-Flow Disposable Filter Units" are both sterile and disposable/meant for single use for one compound.... Yes, I understand someone has already chimed-in and mentioned it previously....
* Yes, you can actually & easily run/filter over 150ml through the 150ml
Nalgene Rapid-Flow Sterile Disposable bottle top Filters as long as it's the same compound, etc...... I used them b-4 w/ great success.... Twas in a pinch on more than one occasion, & probably had easily 200-250ml of Test E. that needed to be filtered... I already had my own 250ml Glass Media Bottle w/ 45mm wide neck on hand + attached, so running through an additional 100ml of Test E. was no problem w/ that unit, etc....
Here are my question(s) for you?
Are you buying the "complete" Filtering unit w/ plastic media bottle inclusive too, or just the .22um bottle top filter? ALL "complete" units are sold w/ garbage plastic media bottles... Hence, once you start applying your vacuum pump pressure and suction, the plastic media bottle is guaranteed to crack, and you're screwed...Thus, you need to provide & should already own your own GLASS MEDIA BOTTLE(s)... Now, those .22um Nalgene Rapid Flow Bottle Top filters are actually sold w/ two different Neck sizes: 33mm, and/or 45mm widths.... Better know the neck size of your own glass media bottle, or you're screwed too... Yes, I've ordered the incorrect size b-4 as I had no clue years ago.... I personally only use the wider 45mm screw on neck size width via my glass media bottles as it gives more support to unit and base & avoids possible tipping over during the filtration process... Just FYI and food for thought....
