Qualitative Filter Paper - 1213-270
Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. Lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.
Key Filter Paper Characteristics
- Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
- Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
- Resin treatment provides the tensile strength to resist tearing under vacuum, even when processing large sample volumes.
- Particle retention rating of 30um defines the separation threshold for the application, determining which solids are captured and which pass through.
- Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. In particular, 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.
