Breaking Down the Features of Pall Acrodisc Sterile Syringe Filters with Supor PES Membrane 32mm, Pack of 50

Specifications

The Pall Acrodisc Sterile Syringe Filters with Supor PES Membrane 32mm, Pack of 50 come with a set of specifications designed for optimal performance in biological and laboratory applications. The Pore Size is listed at 5 µm, a critical specification that determines the size of particles and microorganisms that will be retained. This size is ideal for applications like sterilizing cell culture media or clarifying solutions where larger cellular debris needs to be removed but smaller molecules must pass through.

The Diameter of the filter is 32mm, which is a significant feature. A larger diameter means a greater filtration surface area compared to more common 25mm filters. This increased surface area directly translates to higher throughput and faster flow rates, reducing the time required for sample processing, especially with larger volumes.

The material used is a Supor polyethersulfone (PES) membrane, known for its excellent flow characteristics and low protein binding. This is crucial for biological samples, as it minimizes the loss of valuable proteins and other biomolecules during filtration. The housing is described as modified acrylic, which is chemically resistant and durable.

The product comes in a Pack of 50 units, providing a substantial quantity for regular laboratory use. The Pall No. 4650 is the manufacturer’s internal designation for this specific product configuration. The Color of the housing is Green, serving as an immediate visual cue for the 5 µm pore size.

These specifications are not just technical details; they are the foundation of the filter’s performance. The 5 µm pore size ensures the removal of bacteria and larger cellular components, crucial for sterility. The 32mm diameter significantly boosts efficiency, making it ideal for processing larger volumes quickly. The choice of Supor PES Membrane is key for preserving sample integrity.

Performance & Functionality

The Pall Acrodisc Sterile Syringe Filters with Supor PES Membrane 32mm, Pack of 50 excel in their primary function: providing sterile and particle-free filtrates. The Supor PES Membrane delivers on its promise of high flow rates, making tasks that typically involve slow, tedious filtration significantly faster. This efficiency is particularly noticeable when filtering viscous liquids or larger volumes, where other filters might clog prematurely.

A key strength is the assured sterility. Each filter is individually packaged and sterile-certified, eliminating the risk of contamination from the filtration process itself. The low protein binding characteristic of the PES membrane is another significant advantage, ensuring that valuable biological components are retained in the filtrate rather than adsorbing to the filter material. This translates to more accurate experimental results.

The only area where one might seek improvement is if an even finer pore size were required. While 5 µm is excellent for many sterilization tasks, applications requiring the removal of viruses or smaller colloids would necessitate a different pore size. However, for its intended purpose, the Pall Acrodisc performs exceptionally well, often exceeding expectations for speed and efficiency.
