Grade 93 Qualitative Filter Paper Wet-Strengthened, 125mm, 50 Envelopes of 25 Circles, 1250 Pk SKU: 1093-126

Qualitative Filter Paper - 1093-126

General clarification and sample preparation workflows require a cellulose filter paper with predictable performance across varying sample types. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. Together, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Basis weight of 65g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
• 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.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.

Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. In these cases, standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
