Supor® hydrophilic polyethersulfone membranes offer higher fluid flow rates, lower protein binding, lower extractables, and greater strength than other cellulosic (acetate, nitrate) membranes. Provide some of the highest water flow rates and fluid filtration capacities of any sterilizing grade membrane filter. Nonsterile, except for 28147-979, which is gamma-irradiated.

Supplier: Cytiva

Recommended for microbiological culturing and sample preparation, these cellulose nitrate membrane filters offer very narrow pore size distribution and low levels of extractables.

Supplier: Cytiva

Whatman™ Uniflo™ syringe filters are well suited for rapid, routine syringe filtration of small volume samples up to 100 ml in laboratory sample preparation.

Supplier: Cytiva

These premium syringe filters combine the benefits of a multi-layered prefiltration device with an automation-certified filter housing. The polypropylene housing has been designed to withstand high operating pressures. Some models feature a GxF borosilicate glass prefilter, which provides two to four times the throughput of standard glass fiber prefilter devices, allowing for quick and easy filtration of difficult-to-filter samples.
