Every drop counts

The SaniSure® Cap2v8® Last Drop is a rigid dip tube specifically designed to reach the bottom of any container. Last Drop positions itself directly into the bottom corner or outside edge of a bottle, allowing for the return of every last drop.

The Cap2v8® Last Drop also provides an additional advantage for bottle mixing by positioning itself out of the way from a stir bar.

Customize your assembly

The SaniSure® Cap2V8® Closure Systems range can also be tailor-made to your application. Tubing sizes, lengths, and accessories can be adjusted upon request. Reach out to us to learn more.
