Grade 2589 a Filter Paper for Technical Use, Sheet, 580x580mm, 100/Pk SKU: 10343687

Qualitative Filter Paper - 10343687

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Smooth surface finish allows clear visual assessment of retained solids and supports clean separation of precipitates from filtrate. In turn, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• 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.
• Wet-strengthened construction provides the mechanical durability needed for technical filtration applications under sustained vacuum.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Particle retention rating of Medium defines the separation threshold for the application, determining which solids are captured and which pass through.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. For this purpose, predictable retention and flow rate from a pure cellulose matrix give you a dependable filtration baseline for routine sample preparation. 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.
