Whatman 3-Piece Filter Funnel 530mL, 125mm - 1/Pk - 1950-012

Whatman applies over a century of filtration media expertise, manufacturing under the quality standards that established its products as global laboratory references. A filter funnel draws an entire liquid sample through a seated membrane disc, gathering everything the membrane retains onto one surface for analysis. Glass fiber clears turbid samples ahead of a finer analytical membrane while carrying heavy particulate loads before blinding and captures particulates through its fibrous depth for clarification. Concentrating each sample onto a single membrane underpins the membrane filter technique behind regulated water and beverage microbiology.

Key Characteristics

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

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.

• Sample Pretreatment - Coarse glass microfiber protects downstream membranes from premature blockage on challenging samples.
• Wine and Juice Clarification - Glass microfiber removes haze-forming particulates from wine and juice samples before analysis.
• Total Suspended Solids - Pre-weighed glass fiber discs capture suspended solids from water for gravimetric determination.
• Sediment-Laden Water - High dirt-holding glass microfiber sustains throughput on sediment-heavy environmental water samples.
• 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.
