Container Transpiration

Summary of Findings

Through this study, the following conclusions were drawn:

• Transpiration occurs around the bottle opening and not through the bottle as previously thought.
• Taping the bottle has no influence upon the transpiration rate.
• Bottles that are half full and opened periodically have the highest transpiration rate.
• Opening the bottle periodically greatly increases the transpiration rate.
• Smaller bottles transpire faster.
• 30 ml bottles can not have a 1 year expiration date if certified to an uncertainty of ≤ ±0.6 % relative.
• Transpiration Controlled Technology™ (TCT)¹ totally eliminates transpiration.

Studies involving different bottle construction materials and 'bottle vapor space' have also been conducted and will be published at a later date.

1. Transpiration Controlled Technology (TCT) - a patented technology that virtually eliminates transpiration loss, greatly increasing a standard's shelf life. Developed by Inorganic Ventures for the optimal storage of standards after packaging.
