How do you guys mitigate the cost of Bac water

I am switching to vial spikes for Hospira since it lasts so long. I don't want to keep piercing the stopper and increase coring risk.

I don't like piercing the my daily vial until empty either.

Hmm?

intended for single-vial use and typically provides a microbial barrier for up to about 7 days when proper aseptic technique is followed, such as disinfecting the Clave connector with 70% isopropyl alcohol before each access. It is not specifically rated for 28-day use. The spike should remain attached to the same vial and be discarded after about 7 days, when the vial is discarded, or according to facility protocol, whichever comes first.

Key Features and Benefits

  • Needle-Free Access: Allows for multiple withdrawals from a single vial without using a needle, increasing safety.
  • Venting: Many spikes (e.g., PolySpike) contain a hydrophobic filter that automatically equalizes pressure, preventing vacuum buildup and making extraction easier

    .
    • Contamination Control: Protects against microbial contamination when used with proper technique.
    • Compatibility: Designed for different vial closure sizes, typically 13 mm, 20 mm, or 28 mm.
    • Usage Duration: Often intended for single-vial use, generally recommended to be discarded with the vial or within 7 days, according to facility
 
If you keep your bac 90 days after the first draw, and you’ll keep your reconstituted vials 10 weeks, that seems almost like keeping the same bac in use for 160 days.

I don't understand what I'm looking at here. Why are the room-temp no-air and the room-temp air apparently getting BETTER before they get worse? Is this where I find out that bac ages like wine to a point?

I'm far too lazy to conduct the analysis myself, but I suspect if that chart was redone to show 95% confidence intervals that the it would just be statistical noise. Nobody is seriously suggesting that new benzyl alcohol is forming spontaneously inside of these vials. 🙂

Yes, I am sure of that too - these are just basic tests with base data graphed out on very small sample sizes.

The plot really is a head scratcher, though. Seems odd that "first puncture" would be such a key event in terms of setting the trajectory between 90 and 120 days and seemingly override the different storage conditions and extraction rates between the vials. Without the methodology being spelled out, it does make me wonder if something could have changed with the testing equipment between day 90 and day 120. Perhaps (if analysis equipment was used) its annual calibration was performed between those dates or a different tech was working in the lab that day?

I just found out once opened Bac water vials have 28 days for use. Apparently it cant be frozen to last longer either.

I looked into 3ml bottles but apparently these are not safe for personal use.

How do you guys mitigate the prices?

Answering OP’s original question about price - with a decent organized mass purchasing initiative, you can get legit Hospira 30 ml for $8 including shipping. That’s 80 cents per 3 ml vial, negligible compared to those precious few mg of Chinese mystery powder nestled in the bottom of the vessel.
 
Sorry meant to say sterilise with an alcohol pad. The BAC bottle will suck in air to equalise pressure as you remove BAC but it contains 0.9% benzyl alcohol to inhibit bacterial growth
 
Hospira is good for 90 days with minimal degradation. Store it in a cool, dark place (cupboard)
 
the 28-day rule comes from manufacturer studies done under specific conditions, they tested it, it passed, that's all they can legally claim. Doesn't mean it degrades on day 29.

BAC water contains 0.9% benzyl alcohol precisely to inhibit bacterial growth. As long as you're using a clean needle every time, not injecting air back into the vial, and storing away from heat and light, 90 days is a very reasonable window. That's what I do.
 
So if bac is to be kept in a dark cabinet and fridge or freezer can deteriorate it, when some people freeze reconstituted tirz, why won't the reconstituted vial not deteriorate?

The trick is to store the BAC water inside of an old Pop Tarts box before putting it away, which will nullify the evil powers of your fridge/freezer.

Every time I draw from my Hospira BAC Water, I watch tiny air bubbles go in from one of the previous holes stabbed in from a prior draw. Can't avoid it. That said, I don't think air entering the vial has an effect on the contents in any case.

This is why storing Hospira in the fridge is fine. People can't think logically. There's nothing wrong with it, and it undoubtedly helps it to last longer. The package insert says to store at room temp. Because that's what they tested it at. Too many of us store it in the fridge for it to be a serious problem.

At the end of the day, we all have to do what we're personally comfortable with.
