PALL 4250 Acro 50 Vent Devices with PTFE Membrane - 0.2 µm, hose barb (72/pkg)

The Pall 4250 Acro 50 vent device is designed for sterile air and gas filtration in laboratory and bioprocess applications, such as venting bioreactors, fermentation vessels, and storage containers. It helps prevent contamination while allowing proper airflow.

The 0.2 µm hydrophobic PTFE membrane provides highly efficient removal of bacteria and fine particulates from air and gas streams. It is also chemically resistant, making it suitable for aggressive solvents and harsh laboratory environments.

This model features a stepped hose barb connection, allowing it to fit a range of tubing sizes (typically 1/4" to 1/2" inner diameter). This flexibility makes it easy to integrate into existing lab setups and process lines.

Yes, these vent devices are autoclavable and reusable, allowing sterilization at standard lab conditions (e.g., 121°C). This helps reduce operating costs while maintaining sterile filtration performance.

The Acro 50 design includes a large filtration area (~19.6 cm²) and durable polypropylene housing, which provide high airflow rates, strong pressure resistance, and consistent performance during demanding applications.
