Grade 1 Qualitative Filter Paper, Standard, 150mm Circle, 100/Pk SKU: 1001-150

Qualitative Filter Paper - 1001-150

Pre-filtering turbid samples before instrumental analysis needs a paper grade that removes interfering particles while maintaining reasonable flow rates. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. Together, from fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Standard construction delivers adequate wet strength for conventional filtration while maintaining economical cost for routine applications.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.

Maintaining accreditation requires documented traceability at every step, and the grade specifications above support your audit readiness. In practice, standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
