UniStore™ Sterile PETG Erlenmeyer Flasks

United Scientific UniStore™ Sterile PETG Erlenmeyer Flasks are designed for sterile mixing, storage, and solution handling in research, production, quality control, and life science laboratories. Made from clear PETG polyethylene terephthalate glycol, these flasks provide excellent visibility and easy-to-read graduations while offering a shatterproof alternative to traditional glass vessels.

Each flask is sterilized by gamma irradiation, produced in a 100K clean room environment, and leak proof tested to support reliable performance in controlled workflows. The included vented cap features a 0.20 µm hydrophobic PTFE membrane for continuous gas exchange, making these flasks well suited for culture, media, and biological solution applications.
