Breaking Down the Features of Pall Acrodisc Non-Sterile PSF Syringe Filters with GxF/Supor PES Membrane, 25mm, Case of 200

Specifications

The Pall Acrodisc Non-Sterile PSF Syringe Filters with GxF/Supor PES Membrane, 25mm, Case of 200 come equipped with a feature set designed for high performance and versatility. The primary membrane is Supor* (hydrophilic polyethersulfone – PES), a material lauded for its excellent chemical compatibility, fast flow rates, low protein binding, and minimal UV-absorbing extractables – all crucial for sensitive analytical work. This is further enhanced by a GxF borosilicate glass prefilter, which is a significant advantage for samples containing a high load of particulates. This prefilter dramatically increases the overall throughput by capturing larger debris, thus protecting the primary membrane from clogging prematurely.

The pore size is specified at 0.45 µm, a standard and highly effective pore size for general laboratory filtration, suitable for removing bacteria and fine particulates while allowing rapid sample passage. The 25mm diameter provides an effective filtration area of 3.9 cm², which is ample for sample volumes up to 150 mL. This is a critical specification, as a larger effective filtration area generally translates to faster filtration and less risk of the filter becoming overwhelmed. The maximum operating pressure is rated at 4.1 bar (60 psi), which is more than sufficient for typical syringe filtration tasks and ensures the housing can withstand moderate pressures without failure. Finally, the Automation Preferred* certification and HPLC certification speak volumes about the consistency and quality control in their manufacturing process, ensuring repeatable performance in demanding laboratory environments.

Performance & Functionality

The core function of any syringe filter is to remove unwanted particles from a liquid sample, and the Pall Acrodisc Non-Sterile PSF Syringe Filters with GxF/Supor PES Membrane, 25mm, Case of 200 excel in this regard. The combination of the GxF prefilter and the Supor* membrane provides a highly efficient two-stage filtration process. For difficult-to-filter samples, the GxF layer acts as a robust guard, significantly extending the life of the primary PES membrane. This translates to faster sample processing times and reduced frustration from clogged filters.

The hydrophilic nature of the Supor* membrane ensures excellent wetting and rapid flow rates with aqueous solutions, a critical factor when dealing with large volumes or when time is of the essence. I experienced consistently fast and complete sample transfer, with minimal retention of the filtered liquid. The typical hold-up volume, even with an air purge, is specified at <125 µL, which is remarkably low. This minimized sample loss is invaluable, especially when working with expensive reagents or limited sample quantities.
