Filter Funnel, 3-Piece, 70mm, 115 ml Reservoir, 1 Pk
Whatman SKU: 1950-007

Whatman 3-Piece Filter Funnel 115mL, 70mm - 1/Pk - 1950-007

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. Glass fiber clears turbid samples ahead of a finer analytical membrane while retaining debris through depth rather than a surface and holds a large debris load to extend filtration runs. 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
• Serves as a prefilter that protects finer downstream membranes
• Borosilicate glass microfiber clarifies turbid samples through depth retention

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. Consistent aqueous clarification keeps your sample preparation moving across the buffers and reagents your methods rely on. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.

• 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.
• Particulate Clarification - The depth matrix removes suspended debris from turbid samples before instrumental analysis runs.
• Wine and Juice Clarification - Glass microfiber removes haze-forming particulates from wine and juice samples before analysis.
• 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.
