[Question] Australia — has anyone got a straight answer on lyophilised
Australia — has anyone got a straight answer on lyophilised — that is what I am asking, and I have already read the wiki twice.
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.
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.
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.
If two or three other people have done the same thing we might actually learn something. Alone it is an anecdote.
best — the order this archive was captured in
Gel packs are designed for a duty cycle. A liquid pack at the end of a longer-than-expected transit is a pack behaving as specified, not evidence of an excursion in the vial.
Asked GL Biochem which lines they hold regionally and got a straight list back. That answered my summer ordering question completely.
Small fix — refrigerated, not frozen, once it is in solution.
the excursion that matters is the one after reconstitution
Correction: that stability figure covers the lyophilised powder, not the reconstituted solution. Different claim entirely.
Lyophilisation removes the water that drives most degradation pathways. That is why the dry cake is comparatively robust and the reconstituted solution is not.
Agreed. The dry powder is the robust state; it is the solution that needs the care.
