Real-World Testing: Putting Pall Nylaflo Membrane Disc Filters, Pall Life Sciences 66607, Pack of 100 to the Test

First Use Experience

I initially tested the Pall Nylaflo Membrane Disc Filters in our analytical chemistry lab, primarily filtering aqueous and alcohol-based mobile phases for HPLC. The filters were used to remove any particulate matter that could potentially damage the HPLC column or interfere with the accuracy of our analysis.

The filters performed reliably and consistently across a range of solvent conditions. Their hydrophilic nature made them easy to wet, and their chemical compatibility allowed for use with different types of solvents without any signs of degradation or leaching.

The filters were relatively easy to use with our standard syringe filter holders; no special preparation was required. Filtration proceeded smoothly and without any noticeable pressure build-up, indicating good flow characteristics.

A minor surprise was the consistently low level of background signal in our HPLC analyses after filtering, confirming the claim of low extractables and minimizing potential interferences. This was a welcome improvement over previously used filters.

Extended Use & Reliability

After several weeks of daily use, the Pall Nylaflo Membrane Disc Filters have consistently met our lab’s demanding requirements. There have been no instances of filter rupture or breakthrough.

The filters show no signs of wear and tear, even after prolonged use with different solvents. The nylon material maintains its integrity and does not become brittle or degrade, even when exposed to alcohols and esters.

Maintenance is minimal; there is no need for any specific cleaning or storage procedures beyond the standard laboratory practices. The filters are disposable, eliminating any concerns about cross-contamination or cleaning validation.

In comparison to previous experiences with other filter brands, the Pall Nylaflo Membrane Disc Filters have significantly outperformed in terms of chemical compatibility and low extractables. This has directly translated into more reliable and accurate analytical results.
