Cell and syringe filters are laboratory consumables that are used to remove particulate matter from liquid samples. They are commonly used in cell culture and bioprocessing applications to ensure that the samples are free of debris and contaminants before further analysis or downstream processing.

Cell filters are designed to remove cells and debris from liquid samples. They typically consist of a membrane that is placed in a housing and are available in a variety of pore sizes to accommodate different cell sizes and types. The most common types of cell filters are made of materials such as cellulose acetate, polycarbonate, or nylon and they have different pore sizes that can trap cells or debris of specific size. Some have a low binding surface or are coated with a substance to retain certain type of cells or macromolecules.

Syringe filters are similar to cell filters, but they are used to filter smaller volumes of liquid, typically in the range of a few milliliters to a few hundred milliliters. They are typically used with a syringe and consist of a housing that contains a membrane with a pore size that is appropriate for the intended application. The common type of syringe filter are made from polycarbonate, nylon or mixed cellulose esters and are available in a variety of pore sizes, shapes and diameters.
