Cellulose Qualitative Filter Paper Discs, Grade 05, 3um Retention, 110mm, Very Slow, 100/Pk
GVS SKU: FP110DXS05QALC01

Featuring a refined cellulose medium made from pure cotton linters with an alpha-cellulose content of nearly 100%, this Grade 05 qualitative filter paper delivers the lowest filtration rate and the maximum degree of fine particle retention in the GVS qualitative range. Each 110mm disc provides a nominal particle retention of 3um and a very slow flow rate, making it well suited to difficult filtrations where capturing extra fine-grained precipitates is essential. The low ash content of less than 0.06% means the medium introduces minimal contamination during analytical work.

Key Cellulose Media Characteristics

• Naturally hydrophilic cellulose constructed from refined pulp and pure cotton linters with nearly 100% alpha-cellulose content
• Grade 05 offers the maximum degree of fine particle filtration and retention within the qualitative range
• Very slow flow rate suited to difficult filtration conditions and extra fine-grained precipitates such as barium sulphate and cupreous oxide
• Low ash content of less than 0.06%, not reduced by post-treatment
• Qualitative grade intended for analytical techniques used to determine and identify materials

Key Construction Characteristics

• Cellulose filter paper supplied as 110mm diameter discs
• Nominal particle retention of 3um with a very slow flow speed
• Nonsterile, packaged 100 discs per box

This medium maintains consistent retention performance for clarifying cloudy suspensions, water analysis, and soil analysis. The very slow flow rate maximizes capture of the finest precipitates, helping preserve sample integrity through demanding gravimetric and clarification steps.

• Clarification of Cloudy Suspensions The very slow Grade 05 medium clarifies cloudy suspensions and difficult-to-filter liquids by capturing the finest suspended particles.
• Water and Soil Analysis Provides reliable retention of fine particulates for water and soil testing applications.
• Fine Precipitate Recovery Retains extra fine-grained precipitates such as barium sulphate and cupreous oxide encountered in analytical work.
• Wine Clarification Often specified for clarifying wine where removal of very fine particles is required.
• Qualitative Analysis Used in qualitative analytical techniques to determine and identify materials.
• Difficult Filtration Conditions The lowest filtration rate in the qualitative range handles challenging samples requiring maximum fine particle retention.
