Filter Funnel, 3-Piece, 70mm, 210 ml Reservoir, 1 Pk
Whatman SKU: 1950-017

Whatman 3-Piece Filter Funnel 210mL, 70mm - 1/Pk - 1950-017

Whatman manufactures under Cytiva's quality infrastructure, drawing on a filtration heritage that spans laboratory, environmental, and industrial applications. Built around a membrane held at its base, the funnel routes the whole sample across that membrane and into the flask below. Glass microfiber captures particulates through its fibrous depth for clarification and prepares challenging samples for fine filtration. Concentrating each sample onto a single membrane underpins the membrane filter technique behind regulated water and beverage microbiology.

Key Characteristics

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

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. Consistent aqueous clarification keeps your sample preparation moving as a dependable step in your aqueous sample prep.

• Total Suspended Solids - Pre-weighed glass fiber discs capture suspended solids from water for gravimetric determination.
• Sample Pretreatment - Coarse glass microfiber protects downstream membranes from premature blockage on challenging samples.
• Particulate Clarification - The depth matrix removes suspended debris from turbid samples before instrumental analysis runs.
• Sediment-Laden Water - High dirt-holding glass microfiber sustains throughput on sediment-heavy environmental water samples.
• 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.
