Filter Funnel, 3-Piece, 47mm, 36 ml Reservoir, 1 Pk
Whatman SKU: 1950-004

Whatman 3-Piece Filter Funnel 36mL, 47mm - 1/Pk - 1950-004

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 while carrying heavy particulate loads before blinding and clears turbid samples ahead of a finer analytical membrane. Concentrating each sample onto a single membrane underpins the membrane filter technique behind regulated water and beverage microbiology.

Key Characteristics

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

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification.

• Sediment-Laden Water - High dirt-holding glass microfiber sustains throughput on sediment-heavy environmental water samples.
• Wine and Juice Clarification - Glass microfiber removes haze-forming particulates from wine and juice samples before analysis.
• Particulate Clarification - The depth matrix removes suspended debris from turbid samples before instrumental analysis runs.
• Sample Pretreatment - Coarse glass microfiber protects downstream membranes from premature blockage on challenging samples.
• 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.
