Laboratory syringe filters are used to remove particulate matter and impurities from samples prior to analysis. They are commonly used in a variety of laboratory applications, including filtration of:
Biological samples: For example, to remove bacteria and other microorganisms from culture media, protein samples, or DNA solutions.
Environmental samples: For example, to remove particles and contaminants from water samples or air samples.
Chemical samples: For example, to remove solid particles or impurities from solvents, reagents, or buffer solutions.
Syringe filters are designed to fit onto a standard syringe and consist of a housing, which holds a filter membrane, and a female luer-lock inlet and a male luer slip outlet. When the sample is drawn through the syringe filter, the filter membrane captures any particles or impurities in the sample, while allowing the filtered solution to pass through and be collected in a separate container.
Syringe filters are available in different materials, pore sizes, and configurations, depending on the application and the type of sample being filtered. It is important to select the appropriate filter for the sample to avoid loss of sample or damage to the filter membrane.
