Had a few questions
whats needed to stabilize a fresh batch?
and where's the best place to buy 15ml bottles & caps?
how long after caping the batch could it be tested?
thanks.

The makers guide covers most of this, but doesn't make any purchase source recommendations. We tried to share sources, but that only lead to those sources vanishing.

IIRC, if storing for a long time, unopened, about 2% w/v potassium carbonate prevents gas evolution (the beginning of decomposition), and greatly increases shelf life. That's called stabilization.

The best preservative is epoxidized linseed oil. At about 5% w/v, it acts as an acid scavenger, preventing noxious odors from building up. It also reduces the product's vapor pressure slightly.

Without ELO, baking soda (to neutralize acid) and 3a molecular sieve (to adsorb water from neutralization) would also preserve.

Activated alumina doesn't dust and make the popper cloudy like ms3 does, but the tiny clay particles are inert (it's a cosmetic thing), MS3 works better but makes things cloudy, AA doesn't dry as well but stays clear looking.

You can send a sample in whenever you like. The long equilibrium constant makes the purity Allison around a bit for 21 to 28 days though, you might want to wait. It'll cost about $1,000 USD to test, depending.

All of this is in the guide

I've mostly seen 15ml boston round (or similar) with phenolic cone insert caps

@Canuck Sb...I have a stand, separatory funnel and 2 lbs of Sodium Nitrite ACS grade....and a mag mixer....I'd give them to you FREE if we were close. I'm done making them. LRM's is better than mine....consistency is totally dependent on alcohol/reagent quality at the exact time you are using the reagents for synthesis. And there's no way you can guarantee quality of the alcohol. BTW, TCI Chemical refunded my 40 Bucks for my last purchase of pentanol. It took 3 months, but they never would have refunded me IF they didn't know the stuff loses purity over time.
