2. Decide an appropriate pore size. The pore size of a filter, stated in microns (aka micrometers or µm), is determined by the diameter of particles retained by the filter or by a bubble point test. • Nominal ratings are the pore size at which a particle of defined size will be retained with an efficiency below 100% (typically 90-98%)
KChrom disposable syringe filters provide fast and efficient filtration of aqueous and organic solutions. These syringe filters are made with a wide variety of different membrane filters with a polypropylene housing. They are available in non-sterile varieties and in a wide range of different p

Aijiren 0.45um Sterile PES Syringe Filter is ideal for ion chromatographs, tissue culture filters and protein, nucleic acid and high temperature liquid filtration.
a subsample was filtered over a 0.45-mm syringe filter, and the Zn concentration was determined with inductively coupled plasma optical emission spectrometry (ICP-OES, Perkin Elmer, Avio 200) after appropriate dilution. The pH was meas-ured on the remainder of the suspension. In the first two methods, deionized water was used as extrac-

Sep 02, 2021 · Sample filtration has been shown to be an important tool for improving the results from LC-MS. In part 1 of this two-part blog series, we review the results of some recent studies that looked at the improvements made possible by sample filtration with syringe filters prior to HPLC, and how to obtain these improvements without introducing other unwanted errors and effects.

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.
