The Corning 431446 Aseptic Transfer Cap is a vital accessory tailored for the 2L polypropylene Erlenmeyer flask, designed to facilitate sterile transfer processes in laboratory settings. This innovative cap is particularly beneficial in environments where maintaining aseptic conditions is paramount, such as in cell culture, microbial research, and biopharmaceutical production. Its compatibility with Corning 850 and 1700 cm² plastic disposable roller bottles further enhances its versatility, making it an indispensable tool for researchers and laboratory professionals. The user-friendly design of the cap allows for efficient liquid transfer while significantly reducing the risk of contamination, ensuring the integrity of your experiments.

Crafted from high-quality polypropylene, the Corning aseptic transfer cap is engineered with a venting port that features a 50 mm diameter vent filter, utilizing a 0.2µm pore PVDF membrane. This design ensures optimal airflow while effectively preventing contamination. The liquid transfer port is equipped with a rigid polypropylene dip tube that extends to the bottom of the flask, allowing for complete liquid retrieval. Each cap is individually double bagged and sterile (10-6 SAL), providing users with the confidence needed for stringent aseptic conditions in their laboratory work.
