Pall Polysulfone Filter Funnel 200mL, 25mm - 1/Pk - 4203

Pall Corporation brings decades of membrane filtration expertise to water, beverage, and pharmaceutical microbiology workflows. A filter funnel draws an entire liquid sample through a seated membrane disc, gathering everything the membrane retains onto one surface for analysis. Dead-end filtration through the disc yields a particle-reduced filtrate while holding a uniform rated pore across the membrane and concentrates captured material on the membrane surface. Reproducible recovery of the retained organisms and particulates follows, ready for colony counting, gravimetric weighing, or instrumental analysis.

Key Characteristics

• Dead-end filtration through the disc delivers a clarified filtrate
• Standard disc format suits routine analytical filtration
• Seated membrane retains particulates and microorganisms at the surface
• Uniform rated pore gives consistent retention across the membrane

A clean particulate separation keeps your aqueous sample preparation dependable. Consistent aqueous clarification keeps your sample preparation moving as a dependable step in your aqueous sample prep.
