Transporting a vial for a weekend away — a second dataset Writing it up because I had to work it out twice and would rather nobody else did.

Posting a small dataset on Transporting a vial. It is mine, it is uncontrolled, and the method is stated so it can be discounted appropriately.

What I would like is not agreement but a second dataset collected by someone with no stake in mine. If one exists I would rather read it than argue for this one.

Building on the opening post rather than restating it.

Transporting a vial sits at the boundary between what this community can usefully discuss and what it cannot, and I think it falls on the discussable side, narrowly.

On post #5 — agreed on the reasoning, with one qualification.

I think the Transporting a vial question is answerable and has not been answered, which is a more optimistic position than most of this thread.

Careful with the language on Transporting a vial. "Not detected" and "not present" are different findings and the first is a statement about the method.

Helpful, and short, which on this subject is harder than long.

Agreed on all of that, and I have nothing to add to it.

This follows post #32 rather than contradicting it.

Clarity is a weak test. A solution can lose a significant fraction of its active content to degradation or adsorption while remaining perfectly clear.

One case, stated as one case.

Visible particulate is a strong signal in the other direction: it is a reason to stop and ask rather than to filter and proceed.

Temperature excursions: if a vial sat at room temperature for a time, the question is whether the excursion was long enough to cause damage. Hours at room temperature is usually low risk. Days to weeks raises the risk. If you are unsure, contacting the supplier is more informative than guessing.

Adding this to the thread rather than to the wiki, because I am not confident enough for the wiki.
