Qualitative Filter Paper - 1114-240
Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. Consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.
Key Filter Paper Characteristics
- Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
- Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
- Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
- Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
- Particle retention rating of 25um defines the separation threshold for the application, determining which solids are captured and which pass through.
If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. With these demands in mind, wide retention range availability across the qualitative grade family lets you optimize each application in your sample preparation workflow. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
