Filter Funnel, 3-Piece, 25mm, 16 ml Reservoir, 1 Pk
Whatman SKU: 1950-002

Whatman 3-Piece Filter Funnel 16mL, 25mm - 1/Pk - 1950-002

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. The glass fiber matrix traps suspended solids across its thickness and clears turbid samples ahead of a finer analytical membrane. For the analyst, a consistent membrane seat turns each sample into a countable, weighable, reviewable result.

Key Characteristics

• Serves as a prefilter that protects finer downstream membranes
• Withstands elevated temperatures for demanding sample preparation
• High dirt-holding capacity sustains throughput on particulate-laden samples
• Binder-free options keep extractables low for gravimetric work
• 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. Consistent aqueous clarification keeps your sample preparation moving from the first sample of the day through the last.

• Sediment-Laden Water - High dirt-holding glass microfiber sustains throughput on sediment-heavy environmental water samples.
• 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.
• 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.
• Turbid Sample Prefiltration - Glass microfiber clears heavy particulate loads ahead of a finer analytical membrane below.
