        Qualitative Filter Papers

        GVS Qualitative Filter Papers are the standard for laboratory filtration.

        Using the highest quality material, GVS Qualitative Filter Papers have enhanced mechanical strengths, quality level, and reliability.

        These filter papers are used for qualitative analysis.

        Qualitative filter papers are made of refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100%, which gives them a number of diverse filtration properties.

        The ash content of less than 0,06% is not reduced by post-treatment.

        Properties

        GVS provides a wide range of solution for all application needs:

        GRADE 01 - Medium filtration

        The most widely used filter paper. Medium retention and flow rate. This grade covers a wide range of laboratory applications and is frequently used for clarifying liquids. Traditionally this grade is used in qualitative analytical separations for routine laboratory work as well as rapid filtration of fine precipitates such as lead sulphate, calcium oxalate (hot) and calcium carbonate. In agriculture, it is used for soil analysis and seed testing procedures. In the food industry, Grade 01 is used for numerous routine techniques to separate solid foodstuffs from associated liquid or extracting liquid.

        GRADE 02 - Medium-slow filtration

        GVS provides a wide range of solution for all application needs:

        Slightly more retentive and absorbent than Grade 01 and therefore with a moderate to slow filtration speed. In addition to general filtration GRADE 02 is used for monitoring specific contaminants in the atmosphere, filtration of fine precipitates, soil testing, it is often used as a folded filter in an analytical funnel.

        GRADE 03- Medium-slow filtration (thick)

        Medium to low rate of filtration with double the thickness comparing with GRADE 01. Fine particle retention and excellent loading capacity. The extra thickness gives increased wet strength and allows a higher solute loading. Preferably used for liquids hard to clarify, essences, oils, tinctures, particularly useful for use in Büchner-funnels.

        GRADE 04- Very fast filtration

        Very high rate of filtration with excellent retention of coarse precipitates such as metal hydroxides and sulphides or gelatinous substances. Preferably used as rapid filter for various organic metal precipitates, routine cleanup of biological fluids, food industry analysis, air pollution monitoring (high rates and the fine particles collection is not critical).

        GRADE 05- Very slow filtration

        Lowest rate of filtration and maximum degree of fine particle filtration or retention. Preferably used as a clarifying filter for cloudy suspensions and water and soil analysis. Particularly used in difficult filtration conditions and extra fine-grained precipitates such as barium sulphate, cupreous oxide, often specified for clarification of wine.

        • GRADE 02: Monitoring specific contaminants in the atmosphere; Filtration of fine precipitates such as lead dioxide, calcium fluoride, nickel sulphide and zinc sulphide; Soil analysis
        • GRADE 03: Particularly useful for use in Büchner funnels; Preferably used for liquids hard to clarify, essences, oils and tinctures
        • GRADE 04: Coarse and gelatinous precipitates such as iron hydroxide, aluminium hydroxide and chromium hydroxide ; Silica determination in steel and iron analysis ; Food analysis ; Monitoring of air pollution when the collection of fine particles is not critical ; Routine clean-up of biological fluids or organic extracts
        • GRADE 05: Filtration in very difficult conditions ; Filtration for extra fine-grained precipitates such as barium sulphate, cupreous oxide often specified used for clarification of wine
