Savillex Technical Note: CO2 Ingress Testing on Purillex PETG Square Media Bottles

When utilizing standard laboratory bottles for freeze/thaw applications, one risk is sidewall paneling. Bottles panel for several reasons, including material selection, inadequate sidewall thickness, product shape/design, air egress due to poor closure/seal design, or inadequate closure application during use. In our experience, air egress is the most common cause of paneling and leakage.

Thanks to their lightweight, shatter-resistant nature, PETG (Polyethylene Terephthalate Glycol) bottles are an ideal option for scientists looking to avoid the issues that lead to paneling and leaking. They also boast exceptional gas barrier properties, making them an excellent choice for pharmaceutical and biologics manufacturing applications.

In this technical note, we review the performance of Savillex Purillex® PETG Square Media Bottles after multiple freeze/thaw cycles at -85°C/room temperature and subsequent leak testing. Fill out the brief form to view and download the associated technical note!
