Arista Air-Evac Bottle - 1 Liter

This Air-Evac, accordion-style bottle utilizes a revolutionary accordion design that allows you to compress them down to the level of your liquid. 

This eliminates nearly all the air from the bottle and minimizes wasteful oxidation.

PRO TIP: A variety of environmental factors can reduce the effectiveness of the seal on any plastic bottle. If you experience this, it is recommended to use plumber's tape on the bottle threads. This will fill in gaps, create a more perfect seal, and keep your bottle collapsed to your desired level.
