To filter or not to filter in HPLC? Now, that’s a question.

May 1, 2019 · Preparing HPLC samples using traditional syringe filters often results in the loss of some sample in the syringe. This can make it difficult to get a reading and so you might just decide to save the trouble and not to use the filter at all. This is one of the reasons why we developed the Whatman Mini-UniPrep and glass-based Mini-UniPrep G2

PTFE Syringe Filters - Pall Corporation

The PSF syringe filter has larger effective filtration area compared with the older traditional model, 3.9 cm 2 compared to 2.8 cm 2. This gives the PSF syringe filter a much improved throughput and flow rate. PTFE PSF syringe filters are available with a multi-layered glass fiber prefilter (GxF) above the PTFE membrane.

Syringe Filters - Pall Corporation

Syringe filters are single use, self contained, filtration devices that are typically used to remove contaminating particulate from liquids or gasses. When selecting the correct syringe filter for an application there are a number of factors to consider, these include: Filter and housing materials Pore size Effective filtration area Hold-up volume

Syringe Filters - Sigma-Aldrich

Disposable syringe filters are commonly used for fast and efficient filtering. Selection should be by application. Sterile syringe filters are used to sterilize solutions or clarify sterile solutions, while nonsterile syringe filters are used for general filtration and sample purification.
