UniStore™ Vented Cap Erlenmeyer Flasks

United Scientific UniStore™ Sterile PC Erlenmeyer Flasks are designed for mixing, containing, and storing solutions in sterile laboratory workflows. Made from crystal-clear PC, these flasks offer excellent visibility, easy-to-read graduations, and shatterproof performance that makes them a dependable alternative to glass.

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

With a temperature range of -80°C to 130°C (-112°F to 266°F), UniStore™ PC Erlenmeyer flasks offer broader temperature compatibility than PETG options, making them well suited for demanding lab environments.
