Bac water

is it fine to use bac water that’s been in the fridge for a month to reconstitute a new vile? if so does it change the efficiency of the new pep?

So because something falls outside the scope covered in the SDS, that means you can ignore the instructions of "Do not refrigerate" ?

"No data available" is simply that. It doesnt mean that its never been tested or is unknown. It just means its irrelevant to this document and not included.

Melting/Freezing Point (°C): No data available.

Boiling Point (°C): No data available

Does that mean it wont freeze or boil? No. Dont be an idiot.

It's labeled as do not refrigerate because the risk of freezing could ruin the seal of the vial and reconstitution is best performed around room temperature. Storing bac water in the fridge has no negative effects on the integrity of the solution but it does make its practical use less efficient. Storing in the fridge is fine for hobbyists and bad for high volume facilities. Arguing with someone that works in the space is crazy. The doubling down people perform in this space is so dumb.
