insulin syringe

the bacteriostatic water advice in here is 3 years out of date. Not a hot take, just something I have not seen said plainly here. The numbers the title promised, since…

reconstitution — what am I missing here. If this has been answered properly somewhere, link me and I will delete. The dead space question sent me down a rabbit hole for…

unpopular opinion: most of what gets said here about mg/mL is guesswork, and I am aware this is a minority view on this board. I keep a laminated card in the drawer…

The title is the whole question — how do you actually verify concentration — but here is why I am asking. Started reconstituting everything to a round concentration and…

unpopular opinion: most of what gets said here about concentration is guesswork. Change my mind, genuinely — I have no stake in being right about this. The failure…

units are volume, mg are mass, this is the #1 error on this site. It comes up every few weeks and the answer has not changed. Aim the stream down the wall of the vial…

the reconstitution advice in here is 3 years out of date, and I am aware this is a minority view on this board. 3 years. Those are measured, not estimated, and not…

cloudy after reconstitution — discard, right? right. Not a hot take, just something I have not seen said plainly here. Adding more water does not change how much…

your bac water is fine, your fridge door is not. That is the post. The justification is underneath. Asked SGN what volume they reconstitute to for their own stability…

mg ÷ mL, that is the whole formula, why did i find this hard, which sounds obvious until you try to state the evidence for it. Started reconstituting everything to a…

genuine question about reconstitution that I am slightly embarrassed to ask — that is what I am asking, and I have already read the wiki twice. The failure modes I have…

the mg/mL advice in here is 3 years out of date. Change my mind, genuinely — I have no stake in being right about this. The relevant figures are 3 years, and they come…

Asking properly rather than in a comment on somebody else’s thread: genuine question about mg/mL that I am slightly embarrassed to ask. Aim the stream down the wall of…

three years of reconstitution threads, summarised so you do not have to read them. Not a hot take, just something I have not seen said plainly here. Wrote the date on…

10mg vial + 2mL bac water, i want 2.5mg, how many units, and I am aware this is a minority view on this board. Hard numbers: 10mg, 2mL and 2.5mg. Anything softer than…

Thinking out loud about this: someone check my arithmetic before i draw this up. The failure modes I have actually seen posted here, in order of frequency. One:…

let the alcohol swab dry before you puncture, that is the step everyone skips, and I say this having got it wrong myself for long enough to be annoyed about it. The…

The title is the whole question — why does nobody talk about units — but here is why I am asking. Started reconstituting everything to a round concentration and the…

Something I keep coming back to: mg/mL is doing more work than we give it credit for. Bacteriostatic water contains benzyl alcohol as a preservative, which is what…

someone explain bacteriostatic water to me like I have not read a paper in years. I am not trying to be the "source?" guy. I would just like a source. The lyophilised…

how much of what we believe about mg/mL actually comes from insulin syringe threads, and I want the answer with the reasoning attached rather than just the conclusion.…

dead space — what am I missing here. I would rather ask a basic question now than get this wrong quietly for two months. Adding more water does not change how much…

Posting this as a discussion rather than a claim: the dead space thing finally clicked for me and I want to write it down. Why "more water" keeps confusing people,…

the insulin syringe advice in here is 2 years out of date, and I am aware this is a minority view on this board. The numbers the title promised, since a headline…

why does nobody talk about concentration. Searched first, found three threads that contradict each other, hence the post. Wrote the date on the vial as well as the…
