help me understand lyophilised, I have read the wiki twice
help me understand lyophilised, I have read the wiki twice. Searched first, found three threads that contradict each other, hence the post.
Put a logger in three consecutive orders. Two never went above the range at all and the third spent four hours warm on a Friday. Cost me almost nothing to stop wondering.
A transit temperature logger records a distribution, and time above a threshold matters as much as peak temperature. That is the argument for logging rather than guessing.
Regional stock changes the question rather than answering it: shorter lanes mean less exposure and fewer variables, which is why the warehouse question is worth asking before ordering in summer.
That is everything I have. The rest is opinion and I have tried to keep it out.
best — the order this archive was captured in
You cannot infer potency from a temperature record. The record tells you what happened to the box; only a test tells you what happened to the material.
if you want to know, log it, otherwise you are guessing
ask what storage condition the stability statement was written against
a warm gel pack tells you the pack failed, not that the material did
transit temperature is a distribution, not a number
Small fix — refrigerated, not frozen, once it is in solution.
a summer lane and a winter lane are different lanes
Do you know what storage condition the stability statement covers?
Correction: that stability figure covers the lyophilised powder, not the reconstituted solution. Different claim entirely.
lyophilised powder is far more forgiving than the panic threads suggest
That is a lane problem rather than a packaging problem, and the fixes are different.
Left up and added to the lane table. Origin, destination and month were all included, which is all we ask.
Which lane, and had it been quoted at that transit time?
the excursion that matters is the one after reconstitution
write the reconstitution date on the vial
Yes — reconstitution date on the vial. It is the number you will want and cannot reconstruct.
This. A liquid gel pack on arrival tells you about the pack’s duty cycle, not about the vial.
I would not freeze it in solution. That is a different failure mode and a worse one.
the door shelf is the worst place in the fridge
Asked Homopeptide which lines they hold regionally and got a straight list back. That answered my summer ordering question completely.
Same. Door shelf is the worst place in the fridge and it is where everybody puts them.
