Breaking Down the Features of Pall Acro 50 Vent Filters, Pall Life Sciences 4400, Pack of 18

Specifications

The Pall Acro 50 Vent Filters, Pall Life Sciences 4400, Pack of 18 are engineered with meticulous attention to detail, ensuring optimal performance in critical applications. The core of their efficacy lies in the hydrophobic PTFE membrane with a precise 0.2 µm pore size. This pore size is crucial for ensuring effective filtration of bacteria and particulates, maintaining a sterile environment.

The filter housing is constructed from polypropylene, a material known for its chemical resistance and ability to withstand high temperatures, making it ideal for autoclaving. Each filter boasts an effective filtration area of 19.6 cm², which, combined with the large surface area of the membrane, allows for high flow rates. The filters are designed to handle a maximum operating pressure of 4.1 bar (60 psi) at ambient temperatures, providing a robust safety margin for most laboratory applications.

The stepped hose-barb connectors are a thoughtful design element, offering versatility by fitting tubing with an I.D. from 1/4″ to 1/2″ (6.4-12.7mm). This adaptability simplifies setup and reduces the need for multiple connector types. The maximum operating temperature is rated at 130°C (266°F), comfortably accommodating standard autoclaving procedures. The overall dimensions, with a diameter of 7.3 cm (2 7/8″) and an overall length of 8.2 cm (3 7/32″), contribute to their efficient integration into existing lab infrastructure. The product is conveniently packaged as a Pack of 18, offering excellent value for routine laboratory needs.

Performance & Functionality

In terms of pure functionality, the Pall Acro 50 Vent Filters, Pall Life Sciences 4400, Pack of 18 excel in their primary role: providing reliable, sterile venting. The 0.2 µm PTFE membrane delivers exceptional particulate and bacterial retention, which is non-negotiable for sensitive experiments. Its hydrophobic nature ensures that water-based solutions are not drawn through, preventing contamination of the gas stream.

The large surface area is not merely a spec; it directly translates to practical performance. It means faster filtration and venting, reducing the time required for experiments and processes. This efficiency is vital when dealing with time-sensitive biological cultures or when purging culture vessels with sterile gas. The consistent flow rate, even under pressure, is a clear strength.

A minor point for consideration might be the connector type. While the stepped barb is versatile, for very specific or rigid tubing setups, an adapter might be needed, though this is a rarity given the broad range it covers.
