Filter Funnel, 3-Piece, 70mm, 400 ml Reservoir, 1 Pk
Whatman SKU: 1950-027

Whatman 3-Piece Filter Funnel 400mL, 70mm - 1/Pk - 1950-027

Whatman manufactures under Cytiva's quality infrastructure, drawing on a filtration heritage that spans laboratory, environmental, and industrial applications. Each funnel concentrates the organisms and particulates a sample carries onto the membrane face, leaving them ready to lift onto a plate or balance. High dirt-holding capacity sustains throughput on turbid water samples while clearing turbid samples ahead of a finer membrane and retains debris through depth rather than a single surface. Reproducible recovery of the retained organisms and particulates follows, ready for colony counting, gravimetric weighing, or instrumental analysis.

Key Characteristics

• Withstands elevated temperatures for demanding sample preparation
• Binder-free options keep extractables low for gravimetric work
• High dirt-holding capacity sustains throughput on particulate-laden samples
• Borosilicate glass microfiber clarifies turbid samples through depth retention
• Serves as a prefilter that protects finer downstream membranes

A clean particulate separation keeps your aqueous sample preparation dependable. Consistent aqueous clarification keeps your sample preparation moving across the buffers and reagents your methods rely on.

• Sediment-Laden Water - High dirt-holding glass microfiber sustains throughput on sediment-heavy environmental water samples.
• Particulate Clarification - The depth matrix removes suspended debris from turbid samples before instrumental analysis runs.
• Total Suspended Solids - Pre-weighed glass fiber discs capture suspended solids from water for gravimetric determination.
• Turbid Sample Prefiltration - Glass microfiber clears heavy particulate loads ahead of a finer analytical membrane below.
• Wine and Juice Clarification - Glass microfiber removes haze-forming particulates from wine and juice samples before analysis.
• Sample Pretreatment - Coarse glass microfiber protects downstream membranes from premature blockage on challenging samples.
