The nonwoven polypropylene prefilters (with nominally-rated pore sizes) are constructed with 100% polypropylene, and exhibit similarly low extractables and broad chemical compatibility. Although technically hydrophobic, the polypropylene prefilters are easily water wetted at modest differential pressures.The filters can tolerate pH from 1 to 14

syringe filter membrane performance. Generally, 0.45 µm porosity filters are used to remove particulates from samples and mobile phase solutions. For sterile-filtration, a 0.20 µm porosity filter can be used. Application / Sample* Recommended Filter First

The membranes in Nalgene analytical filter units and funnels are CN (Cellulose Nitrate – a mixed cellulose ester with a predominance of cellulose nitrate material); 0.2 µm for trapping small bacteria and particles, or 0.45 µm pore size for standard microbial QC work.

From each sample filtered by 0.45-μm pore diameter filter, 900 μL was taken and deposited in a 1-mL muffled amber vial. As the ionic strength of the sample must be equated with the ionic strength of the mobile phase, 100 μL of 0.6 M acetate buffer was added. It

Ensuring the correct filtration membrane has been selected from different types of filter materials is often overlooked in routine laboratory sample filtration. Here, we explore different filtration properties and how to take a preventative—rather than reactive—approach
