NaOH solution not stable
Your questions has two a two part answer.

(1) How would you get the $\ce{NaOH}$ out of a sealed bottle?

(2) A concentrated stock solution can be made for $\ce{NaOH}$. In the top of the bottle you use a drying tube stuffed with solid $\ce{NaOH}$ to remove $\ce{CO2}$ from air. On the bottom you have an outlet from which you pour the $\ce{NaOH}$. The gist is that $\ce{Na2CO3}$ is the least soluble carbonate. So most of the $\ce{CO3^2-}$ in the original solution participates. So if you let the solution sit for a couple of days it will be very stable. 

The point with the stock solution as outlined is that $\ce{Na2CO3}$ "sticks" to inside of the container and doesn't flow out with solution. (You don't shake bottle up like you do with tomato juice that you drink to resuspend the solids.)  

So for (1) it is high near impossible to make a $\ce{NaOH}$ solution without some $\ce{CO3^2-}$ in it. The $\ce{NaOH}$ itself has $\ce{CO3^2-}$ unless it is specially made, sealed in argon and so on. 

So your stock solution is concentrated. I boil some distilled water to get rid of $\ce{CO2}$ and seal it till it cools. I then take $10~\mathrm{ml}$ of my stock $\ce{NaOH}$ solution and dilute to $250~\mathrm{ml}$ (or whatever ratios) to get the desired concentration of $\ce{NaOH}$. (That I can check with KHP titration.)
