Filter Funnel, 3-Piece, 90mm, 200 ml Reservoir, 1 Pk
Whatman SKU: 1950-009

Whatman 3-Piece Filter Funnel 200mL, 90mm - 1/Pk - 1950-009

Whatman manufactures under Cytiva's quality infrastructure, drawing on a filtration heritage that spans laboratory, environmental, and industrial applications. Filter funnels seat a membrane disc across the base of the funnel so a full sample passes through in one contained step. The microfiber layer protects downstream membranes from premature blockage while holding a large debris load through the run and retains debris through depth rather than a single surface. Across routine monitoring programs, that clean separation supports defensible colony counts and traceable particulate determinations.

Key Characteristics

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

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.

• Turbid Sample Prefiltration - Glass microfiber clears heavy particulate loads ahead of a finer analytical membrane below.
• 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.
• 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.
• Wine and Juice Clarification - Glass microfiber removes haze-forming particulates from wine and juice samples before analysis.
