the dead space question that gets asked weekly, answered properly. It is the sort of thing everyone half-believes and nobody writes down. Wrote the date on the vial as…
dead space is the most under-discussed thing on this board, and I am aware this is a minority view on this board. The whole calculation, once, with real numbers. You…
genuine question about insulin syringe that I am slightly embarrassed to ask. I am not trying to be the "source?" guy. I would just like a source. The whole…
mg/mL — 16 things I got wrong before I got it right. Not a hot take, just something I have not seen said plainly here. Wrote the date on the vial as well as the…

Genuine question, and the title is the question: does bacteriostatic water actually matter or is it forum lore at this point. Asked JEEP what volume they reconstitute…
The title is the argument: bacteriostatic water is doing more work than we give it credit for. Here is the rest of it. Started reconstituting everything to a round…
Slightly embarrassed to be asking this, but: bacteriostatic water — what am I missing here. Bacteriostatic water contains benzyl alcohol as a preservative, which is…
Thinking out loud about this: the dead space advice in here is 3 years out of date. The relevant figures are 3 years, and they come from the same log I have kept the…
proposal — a flair for reconstitution posts — posting the reasoning in public because a policy you cannot inspect is just a preference. Shook the first vial because…
the concentration table going round is off by a factor of ten, written plainly and without the jargon that usually swallows this topic. The lyophilised cake displaces a…
The title is the argument: unpopular opinion: most of what gets said here about dead space is guesswork. Here is the rest of it. The arithmetic in full: concentration…
we are measuring bacteriostatic water at the wrong time and calling it noise. It is the sort of thing everyone half-believes and nobody writes down. Adding more water…
Question in the title, detail here: does needle dead space actually matter at 2.5mg doses. Numbers, in the order they matter: 2.5mg. I keep a laminated card in the…
why does nobody talk about dead space. I would rather ask a basic question now than get this wrong quietly for two months. Wrote the date on the vial as well as the…

glbiochem.netthe dead space rule is doing its job and people should stop complaining. Comments open, and the wording is genuinely up for discussion. Bacteriostatic water contains…
Posting this as a discussion rather than a claim: the units question that gets asked weekly, answered properly. Shook the first vial because nobody told me not to. It…
three years of concentration threads, summarised so you do not have to read them — a position I have arrived at slowly and would like tested. Why "more water" keeps…
can we stop arguing about dead space until somebody posts a number. I would rather ask a basic question now than get this wrong quietly for two months. Adding more…

the units rule is doing its job and people should stop complaining. Short post, long comment section, probably. Research-use-only material is not approved for human…
Thinking out loud about this: 28 days at room temp after first puncture — where does that number come from. The numbers the title promised, since a headline without…
Slightly embarrassed to be asking this, but: how do you actually verify dead space. Asked WWB what volume they reconstitute to for their own stability testing and they…
Thinking out loud about this: reconstitution is the most under-discussed thing on this board. The failure modes I have actually seen posted here, in order of frequency.…
Asking properly rather than in a comment on somebody else’s thread: how much of what we believe about bacteriostatic water actually comes from units threads. Shook the…
The arithmetic and the technique. Bacteriostatic versus sterile water, reconstitution volume as a concentration choice, converting mg/mL into insulin-syringe units, dead space, swirl-not-shake, stopper coring, and how long a reconstituted vial is actually good for. Math errors get corrected fast and politely.
Independent HPLC and mass spec. The number you get is the number they found.
