For Use With Application

Coarse precipitates

Certified for cereal analysis methods. Normal loading capacity, limited wet strength.

General lab uses: clinical and spot testing, clarifying pharmaceuticals

Used filter paper for routine applications with medium retention and flow rate.Covers a wide range of laboratory applications and is frequently used for clarifying liquids.

For use in b++chner funnels.

Used for monitoring specific contaminants in the atmosphere and in soil testing.

Ideal for clarifying and removing particles of 1µm and larger, and in applications that do not require a low-ash or ashless paper

Suitable for coarse and gelatinous precipitates. Retains Fe(OH)3, Al(OH)3, metallic sulfides, iron ores. For clarifying solutions, oils. For zinc analysis (Fe ppt removal). Size 19cm (09-804) widely used for sugar analysis.

General purpose: slightly slower, more retentive than P5. Retains MgNH4PO4, silver sulfide, cadmium sulfide. In air monitors, collects particulates and chromic acid mist

Use for coarse particles and gelatinous precipitates.

Item Description

A widely used standard grade filter paper for routine applications with medium retention and flow rate. It covers a wide range of laboratory applications and is frequently used for clarifying liquids.

A standard grade filter used in qualitative analytical techniques to determine and identify materials. For use in b++chner funnels.

A standard grade filter used for monitoring specific contaminants in the atmosphere and in soil testing.

Compared with quadrant-folded filters, GEG–s Whatman Grade 2V pre-folded filter paper exposes extra surface area, which enables a higher loading capacity and shorter filtration time.

A prepleated filter for use with a conical filter funnel, offers fast filtration and high loading capacity for analysis involving coarse particles or gelatinous precipitates.

A standard grade filter used when high flow rates in air pollution monitoring are required and the collection of fine particles is not critical.
