Grade 0790 1/2 Application-Specific Filter, Folded, 185mm, 100/Pk SKU: 10301647

Qualitative Filter Paper - 10301647

Pre-filtering turbid samples before instrumental analysis needs a paper grade that removes interfering particles while maintaining reasonable flow rates. Uniform pore distribution across the sheet area ensures consistent particle capture from center to edge during gravity filtration. As a result, from fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.

Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. With this in mind, broad grade availability lets you match retention, flow rate, and thickness to each specific application in your method library. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
