How to Remove Cotton From Nitroglycerin Bottles

Cotton is placed in nitroglycerin tablet bottles to protect the tablets during shipping. The cotton in the bottle actually degrades the nitroglycerin. The nitroglycerin tablets in the bottle emit a vapor during storage. The cotton draws in the vapor and reduces the potency of the tablets. To extend the shelf-life and effectiveness of your nitroglycerin you must remove the cotton the first time you take a tablet.

Instructions

1. Open the bottle when it is time to take your first tablet.

2. Pull the cotton out with your fingertips.

3. Take out a tablet and close the bottle quickly.

4. Discard the cotton in the trashcan.

5. Wash your hands.
