Description

PALL AP-4425 Acrodisc PSF Syringe Filter with Supor® Membrane - GxF/0.45 µm, 25 mm (50/pkg 200/cs)Syringe filters are used in analytical chemistry applications to remove particulate contamination prior to analysis. Filtering a sample prior to sample injection into analytical instrumentation will help protect sensitive parts of the instrument from particulate build up and reduce system downtime. Sample filtration using syringe filters containing 0. 45 m (HPLC) or 0. 2 m (UHPLC) pore size membranes will also extend the life of chromatography columns

Syringe filters are used in analytical chemistry applications to remove particulate contamination prior to analysis. Filtering a sample prior to sample injection into analytical instrumentation will help protect sensitive parts of the instrument from particulate build-up and reduce system downtime. Sample filtration using syringe filters containing 0.45 μm (HPLC) or 0.2 μm (UHPLC) pore size membranes will also extend the life of chromatography columns by preventing particulate from blocking the flow path between the column packing.

Supor membrane is ideal to use for the filtration of general aqueous samples. The GxF/Supor membrane configuration features a a GxF multi-layer glass fiber prefilter, providing two to four times the throughput of standard prefilter devices. The multi-layer prefilter captures particulate rated from > 40 to 1 μm.

Great functionality

Great q-tips. They are soft and easy to use. My only complaint was how they were shipped. They shipped with no box at all. Just a label slapped on it.
